【摘要】 以香蕉李 (PrunussalicinaLindl.)成年树为试材 ,用N - (2 -氯 - 4-吡啶基 ) -N′ -苯基脲(CPPU)、赤霉素 (GA3)和复合果树促控剂 (PBO)等 3种生长调节剂于上年采果后 1个月、当年谢花期和幼果期进行喷布处理 .结果表明 ,以外源生长调节剂处理花期、幼果期的香蕉李 ,其生理落果大为降低 ,果实的含糖量增加 ,果实品质得到一定程度改善 ,叶片叶绿素含量也有所提高 ,叶片可溶性糖含量有所降低 ,其中以GA3及CPPU处理效果最好 .更多还原

【Abstract】 The effects of 3 plant growth regulators (CPPU,GA 3 and PBO) on fruit set, yield and quality of Prunus salicina Lindl.cv.xiangjiaoli were studied. The results showed that all above growth regulators increased the fruit set rate,yield and quality. Of those, the effects of PBO were the best.更多还原
