Although many people have opinions concerning the vigo f'rd-ferbtofo'laqe
plant cultivars, direct comparisons of growth or rooting rates are lacking.
This type of information is important in breeding programs, where attempts are
often made to increase vigor of plants which will be propagated asexually;this
is especially important in the genus Aglaonema. This study was conducted to
test the rooting ability of six commercial Aglaonema cultivars and one parental
breeding line (Aglaonema crispum 'Chartreuse Halo') which was selected for its
leaf size and apparent vigor.
The seven cultivars used in this study (Table 1) had been maintained at
the Agricultural Research Center Apopka. Twenty cuttings with 5-6 leaves were
harvested from each cultivar on March 19, 1982. The basal cut was made in the
middle of the node below the oldest leaf. Cuttings were placed in a rooting
medium of equal parts peat moss and perlite which was maintained at a constant
26-270C with an electric heating cable. Misters were set to run for 15 seconds,
every 15 minutes from 8:30 a.m. to 5:30 p.m. daily. A total of 140 cuttings was
placed in a propagation bench, in a randomized block design, and left for 6 weeks
at which time the total number of roots (longer than 1 cm) per cutting was count-
ed and the longest root was measured (cm).
Aglaonema crispum 'Chartreuse Halo' produced a mean number of 21.3 roots
compared to 17.1, 15.1, and 14.4 for A. 'Silver Queen', A. x 'Manila', and A.
x 'Abidjan', respectively (Table 1). Aglaonema 'Fransher' yielded a mean of
4.4 roots per cutting. Most cultivars had an average longest root length
in the range of 6-8.0 cm with the exception of A. modestum which had an
average of 14.4 cm. Aglaonema 'Fransher' had a mean root length of 3.8 cm.

z20 cuttings per cultivar in a 1:1 peat/perlite rooting medium held at 26-270C
with an electric heating cable. Experiment initiated March 19, 1982.
Although it did not produce the largest number, A. modestum yielded roots
which were consistently much longer (although thinner) than any other cultivar.
Aqlaonema 'Chartreuse Halo' rooted the best overall followed closely by A. x
'Silver Queen', and two other hybrids A. x 'Manila', and A. 'Abidjan'. Aglaonema
'Chartreuse Halo' has been a good plant for breeding studies even though it lacks
sufficient foliar color to be a widely used commercial cultivar. Results from
this study indicate that attempts to combine its vigor with better foliar color
should continue. The fact that the next three best rooting plants were hybrids
indicates the value of hybridization for increasing vigor of Aglaonema.
