摘要
以６～１０ 年生的几个枇杷品种为试材，进行ＧＡ＋ ＣＰＰＵ 不同的浓度、使用时期和时期组合试验，结果表明：用ＧＡ１ ０００ ｍ ｇ·ｌ－ １处理花蕾，再用ＧＡ１ ０００ ｍ ｇ·ｌ－ １＋ ＣＰＰＵ２０ ｍ ｇ·ｌ－ １在花后１ 月下旬、２ 月下旬、３ 月下旬分期喷果３ 次，是增大无核果和防止无核果落果的重要措施；无核果率１００ ％ ，无核果单果重与对照正常果单果重差异不显著，其果肉厚、可食率均极显著高于对照，生理病果较少；可溶性固形物含量极显著低于对照，果形指数显著大于对照，成熟较迟。
Resultsofexperim entshow ed thatspraying GA 1 000 m g·l- 1 atthe flow er bud stage, and then spraying GA 1 000 m g·l- 1+ CPPU 20 m g·l- 1 in the last 10 days of January,February and March separately w as crucialim portance for enhancing the seedless fruit grow th and prevent fruit drop.The percentage of seedless fruits w as reach 100 % .No significant difference w as ob- served in the single fruit w eightbetw een the seedless fruit and the control.The thickness offlesh and edible rate oftreated fruit w ere extrem ely higher than control(in P= 0.01 level),the physio- logicaldisease of fruit w ere less,but the totalsoluble solid content w as significantly low er than control,the fruit L/D ratio w as larger than control,and the m aturation w as delayed.The problem concerning above treatm entw as discussed.
