PENGARUH ZPT TERHADAP KUALITAS BUAH MANGGIS
Abstrak: The objectives of
this experiment was to examine the influence of polyamine, gibberelline and
harvesting times to inhibit ripening process and to maintain postharvest
quality on mangosteen. The method applied was randomized block design with two
factors and three replications. First factor was harvesting time consisting of
14, 15 and 15 weeks after anthesis. Second factor is chemical concentration
consisting of control (aquadest), GA3 (150, 200, 250 mg/l), polyamine (0,3; 1
and 3 mM). The result showed that spermidine application at 1 mM was more
effective to maintain the postharvest quality of mangosteen, the fruit remained
soft and the climacteric peak was longer than that of control. Gibberelline
application showed unsightly result compared to control. Mangosteen fruits with
harvesting time of 15 and 16 weeks after anthesis had better perfomance than
those of harvesting at 14 weeks after anthesis, the fruit was remained soft and
the weight lost was less.
