STORAGE OF DIEFFENBACHIA SPRAYED WITH BA

There is increasing interest in shipment of foliage l lat bo 2-4
weeks, since plants that can endure darkness for 4 weeks can be transport ed
by ship to most parts of the world. BA, 6-benzy1ldidhmViivaod-y]'(,
prolongs storage life of plants and delays senescelTCe-y-retarding-Gh4-
phyll and carotene degradation, essential components for photosynthesis.
Previous work suggested BA could be useful in maintaining plant quality of
Dieffenbachia stored for up to 30 days in the dark. The following experiment
was conducted to study effects of BA sprays on Dieffenbachia stored in the
dark.

Dieffenbachia maculata 'Perfection' were grown for 3 months in 8 inch
containers in a shadehouse receiving 1200 ft-c maximum light intensity and
1 level teaspoon of 19-6-12 Osmocote (1) before treatments began. The
experiment consisted of a 3x2x2x2 factorial with BA levels of: 0, 50 and 100
ppm sprayed 1 or 4 days prior to placement in coolers of 55 or 650F for 2 or
4 weeks. The first spray was applied December 11, 1981, with the remaining
plants sprayed December 14, 1981; all plants were placed in coolers
December 15 and removed 2 or 4 weeks later. Plants were then placed in rooms
where they received 125 ft-c from Cool White fluorescent lamps 12 hours daily,
watered as needed and graded March 17, 1982.

A BA spray of 25, 50 or 100 ppm was reported to reduce deterioration of
Dieffenbachia while stored for 30 days. Results of this experiment showed a
slight benefit. Plant grade remained the same for all treatmentsof BA, but a
spray of 100 ppm reduced the average number of leaves damaged from 3.6 to 2.6
(Table 1). BA does show promise as a material that prolongs plant quality
while in the dark, but proper production practices and proper storage during
shipping appear to be the most important.
