Update On APIRS


The Aquatic, Wetland and Invasive Plant Information Retrieval
System (APIRS) continues to grow and change with the rest of the electronic
information world, although some things stay the same.

We continue to collect, catalog and make available published literature on the
subjects of aquatic, wetland and invasive plant biology, ecology, management,
conservation, utilization and much, much more. During the past year, almost 2,000
new items were cataloged and entered into the database, which now contains almost
47,000 items. As many of you already know, APIRS went online three years ago
and is heavily accessed by users around the world via the World Wide Web. To use
the APIRS database online, go to http://aquatl.ifas.ufl.edu/ and follow the
instructions. Some people still prefer to have literature searches performed for them.
During the past year, approximately 300 custom bibliographies were prepared for
over 200 patrons. Bibliographies can be prepared and sent to users via electronic
mail or the postal service, usually the same day of the request. To request a
personalized literature search and bibliography, contact Karen Brown at kpb@gnv.
ifas.ufl.edu Although a lack of funding is an ever-present problem, for now
database services continue to be available free of charge.

The Freshwater Aquatic Fruit: Water chestnut

by Syed Hasib Ahmad, Advisor, Aquaculture & Fisheries, Institutional Finance &
Programme Implementation Dept., Government of Bihar, India, and Arun Kumar
Singh, Senior Lecturer, B.D.E. College, Magadh University, Patna, Bihar, India



Water chestnut (Trapa bispinosa) is an edible aquatic plant that grows
abundantly in the lakes of Kashmir. At Wular Lake it is said to yield 4-5 million kilograms
(approximately 4,000-5,000 tons) of nuts annually. These are scooped up from the bottom
of the lake in small nets and constitute almost the only food for at least 30,000 persons for
five months of the year. Water chestnut has been commercially cultivated in many parts of
India from the most ancient times, particularly in the eastern and southern regions. Water
chestnut is also known as water nut, horn chestnut, bull nut, and buffalo-head fruit. The
plant is commercially cultivated in tropical parts of the world such as Pakistan, Sri Lanka,
Indonesia, and Africa. The plant is abundant in Indonesia, southeast Asia, the southern
part of China, and in the eutrophic waters of Japan, Italy and tropical America. It has
become naturalized in a few places in the eastern United States, apparently through its use
as a decorative aquatic plant.


Waiter chestnut


SThis annual floating-leaved aquatic
,/ x herb belongs to the natural order
S" Trapanaceae, family Trapaceae. The genus
--....* 4r*il Trapa comprises some 30 species that
S.. -exclusively grow in eutrophic water.
Trapa natans Linn. var. bispinosa Makino
is a native of China. The Chinese name of
the nut is Ling Ko, meaning "spiritual
horn." Ling Ko is found all over China. It




is harvested and consumed during the mid-
autumn festival in September to celebrate
the overthrow of the Mongolians during
the Yuan Dynasty in ancient China. Trapa bispinosa Roxb. grows in India and also in
Ceylon. The nut has two (sometimes four) short slender spines in place of the pronounced
horns of the Chinese plant. The fruit with two spines is known as Trapa bispinosa Roxb.,
and the four-spined fruit is known as Trapa quadrispinosa Wall. There is also a four-
spined European species, Trapa natans, commonly known as Jesuit nut, water caltrops, or
water chestnut. These nuts are of a slate brown color whereas the Chinese nut is black.
Based on the color of the husks, water chestnut is categorized into three types: completely
green, completely red, and green blended with red.

About 2/3 of the water chestnut plant floats just beneath the water surface and thus forms a
thick mat in the water column. Only its upper leaves float over the water surface in an
artistic radial pattern with swollen, air-filled petioles that keep the upper part of the plant
afloat. The reddish green leaves are villous on the dorsal side, and 6-8 cm in size. The
submerged leaves (occurring on young plants and not shown in drawing) are laterally
dissected into capillary segments.

Trapa has no primary root. The plant stem remains in the water and has one node of about
3-5 cm in thickness. The submerged stem bears two types of adventitious root. Those near
the base of the stem fix the plant to the muddy substrate. The rest are free-floating fibrous
roots borne in pairs below the leaf bases and are unusual in being green and
photosynthetic.

The flowers are axillary, white in color, with a solitary peduncle. They open above the
surface of the water towards the afternoon. After pollination, the flowers submerge to
facilitate fruit formation. Fruits appear in September in the State of Bihar, and continue up
to December and January, fully ripening in the cold season.

The plant bears edible nuts in hard-shelled fruits which resemble the head of a water
buffalo with its two large curved horns. The fruit has four angles and two out of four
develop in the case of Trapa bispinosa. The fruit is a bony one-seeded nut having very
unequal cotyledons and a top-shaped drupe. The fleshy pericarp covers a large 2-4 horned,
stony endocarp. When ripe, the nuts fall to the bottom of the pond where they remain all
winter as they must be kept moist to retain their viability.




Cultivation
Ponds which are otherwise unsuitable for fish culture are being utilized for farming of this
fruit crop. It is best grown in shallow perennial ponds which hold abundant water
throughout the year.

Trapa can germinate under a wide range of water depths and grows best at .5-1 m. The
maximum water depth should never be more than 1 m, though the plant can grow to a
depth of around 3 m. The plant requires full sunlight and the water level should be full by
August. The pond water must have a high organic content and should be free of high
concentrations of salts. Neutral to somewhat alkaline pH are best for proper growth of the
plant.

In India, the traditional palm tree toddy collector known as "Pasi" by caste and also the
fisher community are engaged in cultivating and marketing of water chestnut. Two
methods are used in cultivation: natural seeding from previous crops, and preparation and
transplanting of seedlings. After the harvest of the seed crop, disease-free, healthy and
large sized fruits are selected for raising in the nursery. While selecting fruits for seeds,
spines of the spinous variety are cut with sharp knives to prevent damaging the outer shell
of seeds during curing and storage.

Selected seeds are stored only after curing with a special technique. The seeding material
should be kept in large barrels or in earthen pitchers which are filled with freshwater and
left undisturbed for two to three days. Afterwards water is changed daily for at least 5-6
days. This is one of the most essential operations. The practice is continued until the hard,
thick outer skin of the fruit rots and the loose coating of the seed detaches from the fruits
and the thin, stony, inner coat is visible. The curing of seed material is done at room
temperature and is completed in about 35-40 days. The objective of curing the seeds is to
prevent spoilage due to rotting of the loose outer shell of the fruits.

Seeds so cured can easily be stored in the same earthen pitcher or barrel, but without water
and covered with a moist cloth or gunny bag to provide high humidity and low
temperature. These containers are kept in a cool, shady place and can be stored for up to 3-
4 months, without affecting seed viability. The seed nuts procured from 1/100 of a hectare
of a normal crop are sufficient to raise seedlings for one hectare.

During the months of March-April, just after the seeds have started germinating, they are
broadcast into small nursery ponds or in small, shallow ditches having 45-60 cm of water.




Before broadcasting, the seeds are coated with a layer of soil on the opposite face of the
germinated portion in order to add extra weight on the non-germinated face and to assure
that after broadcasting, in the manner of a shuttle-cock, the seeds will settle at the bottom
with the germinated face up and the coated face down. They also can be manually sown.
The stem starts emerging and gradually spreads out. During the months of June-July,
seedlings are lifted from the nursery pond and transplanted into larger ponds, ditches, or
reservoirs. For transplantation, the uprooted stems are cut into several smaller pieces.
Some growers fasten 3-4 seedlings together in a bunch, which is thrashed into the pond
bottom by feet.

Lateral shoots commonly known as suckers can be detached from the main mother seed
nut for transplanting. Single seeded water nuts can develop 20-30 and sometimes even up
to 50 such lateral suckers. Each of these laterally developed suckers may very well be able
to send out 5-10 further shoots after transplanting. From sowing to later such formations
takes about 40-50 days. Shoots also arise from the nodes, forming roots and new plants.
Thus, within a month or so, the entire water area gets covered with the luxurious growth of
brownish-green leaves.

Fertilizing the pond with urea is a common practice. This is applied at the rate of 40-50 kg/
ha of pond surface area in two installments at fortnightly intervals, with the first dose
about 20 days after transplanting. The application of 40 kg of nitrogen, 40 kg of
phosphate, and 60 kg of potash per hectare produces better results.

Pests of water chestnut include the beetle, Galerucella birmanica, which is reported to
consume up to 40% of the leaf tissue. Insect pests are controlled by shaking the plants
vigorously under water, by hand-picking, and by dusting or spraying exposed parts of the
plants. Snails are another destructive pest, particularly during the later stage of growth.
Growers remove the snails by hand. Rats also eat nuts and vegetative parts of the plant.

Harvesting of fruit is from September/October through December/January. The entire crop
is harvested in four installments at intervals of 8-10 days because the fruits ripen in
batches. At the time of harvesting, the size, softness of the pulp, greenness of color, and
easy separation of the outer hard cover are the most important characteristics taken into
consideration. Each fruit is plucked by hand after lifting the plants from the surface of the
water. The plant is then put back in position for the next batch of fruits to ripen during the
8 day interval. Quantitatively, the maximum yield is obtained on the second and third
installments of harvesting operations.




In traditional culture, the yield from 1 bigha (4 bigha=l hectare) of pond area, on average,
ranges from 2.4-2.6 quintals (quintal=100 kg. or 220 lbs.). With the application of
inorganic fertilizer and pest control measures, an average yield of 10-12 quintals/bigha has
been obtained.

The commercial marketing of water chestnut has not been fully investigated. Water
chestnuts are sold fresh on the pond bank, or in local markets, where prices and profits
tend to be low.

Editor's Note: All Trapa species are prohibited in the state of Florida. Trapa natans,
introduced to New York State in the late 1800s, now infests sites throughout the
northeastern United States. The plant has aggressive growth habits and forms extensive
surface mats, restricting both recreational and commercial uses of infested water bodies. It
is reported that seeds may remain viable for up to twelve years, making eradication of the
plant especially difficult. Research continues on control methods for this species.

The Chinese water chestnut, Eleocharis dulcis, is grown legally and successfully in
Florida as a food crop. Confusion is frequent since both plants share the same common
name of water chestnut.

Volume 18 number 1 Summer 1998 AQUAPHYTE ONLINE Summer 1998 The Freshwater Aquatic Fruit: Water chestnutby Syed Hasib Ahmad, Advisor, Aquaculture & Fisheries, Institutional Finance & Programme Implementation Dept., Government of Bihar, India, and Arun Kumar Singh, Senior Lecturer, B.D.E. College, Magadh University, Patna, Bihar, India Water chestnut (Trapa bispinosa) is an edible aquatic plant that grows abundantly in the lakes of Kashmir. At Wular Lake it is said to yield 4-5 million kilograms (approximately 4,000-5,000 tons) of nuts annually. These are scooped up from the bottom of the lake in small nets and constitute almost the only food for at least 30,000 persons for five months of the year. Water chestnut has been commercially cultivated in many parts of India from the most ancient times, particularly in the eastern and southern regions. Water chestnut is also known as water nut, horn chestnut, bull nut, and buffalo-head fruit. The plant is commercially cultivated in tropical parts of the world such as Pakistan, Sri Lanka, Indonesia, and Africa. The plant is abundant in Indonesia, southeast Asia, the southern part of China, and in the eutrophic waters of Japan, Italy and tropical America. It has become naturalized in a few places in the eastern United States, apparently through its use as a decorative aquatic plant. This annual floating-leaved aquatic herb belongs to the natural order Trapanaceae, family Trapaceae. The genus Trapa comprises some 30 species that exclusively grow in eutrophic water. Trapa natans Linn. var. bispinosa Makino is a native of China. The Chinese name of the nut is Ling Ko, meaning spiritual horn. Ling Ko is found all over China. It http://plants.ifas.ufl.edu/aq-w98-7.html (1 of 5) [6/6/2008 2:10:57 PM]

Volume 18 number 1 Summer 1998 is harvested and consumed during the midautumn festival in September to celebrate the overthrow of the Mongolians during the Yuan Dynasty in ancient China. Trapa bispinosa Roxb. grows in India and also in Ceylon. The nut has two (sometimes four) short slender spines in place of the pronounced horns of the Chinese plant. The fruit with two spines is known as Trapa bispinosa Roxb., and the four-spined fruit is known as Trapa quadrispinosa Wall. There is also a fourspined European species, Trapa natans, commonly known as Jesuit nut, water caltrops, or water chestnut. These nuts are of a slate brown color whereas the Chinese nut is black. Based on the color of the husks, water chestnut is categorized into three types: completely green, completely red, and green blended with red. About 2/3 of the water chestnut plant floats just beneath the water surface and thus forms a thick mat in the water column. Only its upper leaves float over the water surface in an artistic radial pattern with swollen, air-filled petioles that keep the upper part of the plant afloat. The reddish green leaves are villous on the dorsal side, and 6-8 cm in size. The submerged leaves (occurring on young plants and not shown in drawing) are laterally dissected into capillary segments. Trapa has no primary root. The plant stem remains in the water and has one node of about 3-5 cm in thickness. The submerged stem bears two types of adventitious root. Those near the base of the stem fix the plant to the muddy substrate. The rest are free-floating fibrous roots borne in pairs below the leaf bases and are unusual in being green and photosynthetic. The flowers are axillary, white in color, with a solitary peduncle. They open above the surface of the water towards the afternoon. After pollination, the flowers submerge to facilitate fruit formation. Fruits appear in September in the State of Bihar, and continue up to December and January, fully ripening in the cold season. The plant bears edible nuts in hard-shelled fruits which resemble the head of a water buffalo with its two large curved horns. The fruit has four angles and two out of four develop in the case of Trapa bispinosa. The fruit is a bony one-seeded nut having very unequal cotyledons and a top-shaped drupe. The fleshy pericarp covers a large 2-4 horned, stony endocarp. When ripe, the nuts fall to the bottom of the pond where they remain all winter as they must be kept moist to retain their viability. http://plants.ifas.ufl.edu/aq-w98-7.html (2 of 5) [6/6/2008 2:10:57 PM]

Volume 18 number 1 Summer 1998 Cultivation Ponds which are otherwise unsuitable for fish culture are being utilized for farming of this fruit crop. It is best grown in shallow perennial ponds which hold abundant water throughout the year. Trapa can germinate under a wide range of water depths and grows best at .5-1 m. The maximum water depth should never be more than 1 m, though the plant can grow to a depth of around 3 m. The plant requires full sunlight and the water level should be full by August. The pond water must have a high organic content and should be free of high concentrations of salts. Neutral to somewhat alkaline pH are best for proper growth of the plant. In India, the traditional palm tree toddy collector known as Pasi by caste and also the fisher community are engaged in cultivating and marketing of water chestnut. Two methods are used in cultivation: natural seeding from previous crops, and preparation and transplanting of seedlings. After the harvest of the seed crop, disease-free, healthy and large sized fruits are selected for raising in the nursery. While selecting fruits for seeds, spines of the spinous variety are cut with sharp knives to prevent damaging the outer shell of seeds during curing and storage. Selected seeds are stored only after curing with a special technique. The seeding material should be kept in large barrels or in earthen pitchers which are filled with freshwater and left undisturbed for two to three days. Afterwards water is changed daily for at least 5-6 days. This is one of the most essential operations. The practice is continued until the hard, thick outer skin of the fruit rots and the loose coating of the seed detaches from the fruits and the thin, stony, inner coat is visible. The curing of seed material is done at room temperature and is completed in about 35-40 days. The objective of curing the seeds is to prevent spoilage due to rotting of the loose outer shell of the fruits. Seeds so cured can easily be stored in the same earthen pitcher or barrel, but without water and covered with a moist cloth or gunny bag to provide high humidity and low temperature. These containers are kept in a cool, shady place and can be stored for up to 34 months, without affecting seed viability. The seed nuts procured from 1/100 of a hectare of a normal crop are sufficient to raise seedlings for one hectare. During the months of March-April, just after the seeds have started germinating, they are broadcast into small nursery ponds or in small, shallow ditches having 45-60 cm of water. http://plants.ifas.ufl.edu/aq-w98-7.html (3 of 5) [6/6/2008 2:10:57 PM]

PAGE 9

Volume 18 number 1 Summer 1998 Before broadcasting, the seeds are coated with a layer of soil on the opposite face of the germinated portion in order to add extra weight on the non-germinated face and to assure that after broadcasting, in the manner of a shuttle-cock, the seeds will settle at the bottom with the germinated face up and the coated face down. They also can be manually sown. The stem starts emerging and gradually spreads out. During the months of June-July, seedlings are lifted from the nursery pond and transplanted into larger ponds, ditches, or reservoirs. For transplantation, the uprooted stems are cut into several smaller pieces. Some growers fasten 3-4 seedlings together in a bunch, which is thrashed into the pond bottom by feet. Lateral shoots commonly known as suckers can be detached from the main mother seed nut for transplanting. Single seeded water nuts can develop 20-30 and sometimes even up to 50 such lateral suckers. Each of these laterally developed suckers may very well be able to send out 5-10 further shoots after transplanting. From sowing to later such formations takes about 40-50 days. Shoots also arise from the nodes, forming roots and new plants. Thus, within a month or so, the entire water area gets covered with the luxurious growth of brownish-green leaves. Fertilizing the pond with urea is a common practice. This is applied at the rate of 40-50 kg/ ha of pond surface area in two installments at fortnightly intervals, with the first dose about 20 days after transplanting. The application of 40 kg of nitrogen, 40 kg of phosphate, and 60 kg of potash per hectare produces better results. Pests of water chestnut include the beetle, Galerucella birmanica, which is reported to consume up to 40% of the leaf tissue. Insect pests are controlled by shaking the plants vigorously under water, by hand-picking, and by dusting or spraying exposed parts of the plants. Snails are another destructive pest, particularly during the later stage of growth. Growers remove the snails by hand. Rats also eat nuts and vegetative parts of the plant. Harvesting of fruit is from September/October through December/January. The entire crop is harvested in four installments at intervals of 8-10 days because the fruits ripen in batches. At the time of harvesting, the size, softness of the pulp, greenness of color, and easy separation of the outer hard cover are the most important characteristics taken into consideration. Each fruit is plucked by hand after lifting the plants from the surface of the water. The plant is then put back in position for the next batch of fruits to ripen during the 8 day interval. Quantitatively, the maximum yield is obtained on the second and third installments of harvesting operations. http://plants.ifas.ufl.edu/aq-w98-7.html (4 of 5) [6/6/2008 2:10:57 PM]

Volume 18 number 1 Summer 1998 In traditional culture, the yield from 1 bigha (4 bigha=1 hectare) of pond area, on average, ranges from 2.4-2.6 quintals (quintal=100 kg. or 220 lbs.). With the application of inorganic fertilizer and pest control measures, an average yield of 10-12 quintals/bigha has been obtained. The commercial marketing of water chestnut has not been fully investigated. Water chestnuts are sold fresh on the pond bank, or in local markets, where prices and profits tend to be low. Editors Note: All Trapa species are prohibited in the state of Florida. Trapa natans, introduced to New York State in the late 1800s, now infests sites throughout the northeastern United States. The plant has aggressive growth habits and forms extensive surface mats, restricting both recreational and commercial uses of infested water bodies. It is reported that seeds may remain viable for up to twelve years, making eradication of the plant especially difficult. Research continues on control methods for this species. The Chinese water chestnut, Eleocharis dulcis, is grown legally and successfully in Florida as a food crop. Confusion is frequent since both plants share the same common name of water chestnut.

E-mail: grodowm@exl.wes.army.mil CD -Banks and Buffers A guide to selecting native plants for streambanks and shorelines A CD for Microsoft Windows, produced by the Tennessee Valley Authority This CD consists of a 14-page color booklet and a disk which is the "Riparian Plant Selector", a database of 117 species of native trees, shrubs, vines and herbaceous plants. It contains more than 400 color photographs and a listing of more than 400 nurseries. The guide is specifically designed for the Tennessee Valley, which includes parts of Virginia, North Carolina, South Carolina, Tennessee, Georgia, Alabama, Mississippi and Kentucky. To use the plant selector, the user answers questions as to the site in which the plants would grow, tolerances for water, light and pH, as well as whether the user wants to plant plants that have wildlife value or commericail value. Then the plant selector presents a list of plants that match site conditions and personal preferences. Order from TVA Water Management Library, 1101 Market Street, SCT 7B Chattanooga, TN 37402-2801.
