摘要: 对三个甜樱桃品种二年生幼树叶面喷施多效效62.5×10-6,125×10-6,250×10-6,500×10-6,1000×10-6,及土施0.1,0.3,0.5,1.0,1.5g/m2。结果表明,125×10-6以上的浓度都强烈地抑制树体营养生长。土施后第二年仍能很强地抑制枝条生长,而且明显地促进花芽形成,加速了花芽形态分化的进程。但过高剂量使促花作用减弱。叶面喷施的植株。在施后的第二年,不再有抑制生长的效果,其补偿生长量随施用浓度的加大而增加。B 92000×10-6当年也有明显的抑制效应,但低于250×10-6多效唑的控制量。

Abstract: Experiments were carriedout on Rainier, Bing and Van cherry trees to investigate the effect of paclobutrazol on vegetative growth and flower formation of young cherry trees.Results indicated that both foliage spray with concentration higher than 125×10-8and soil drench with dosages above 0.1g/m2 effectively inhibited shoot growth.Carry-over effect was observed in the soil application treatments.Besides, application of paclobutrazol promoted flower bud induction and development.The inhibitory effect induced by foliar sprayed paclobutrazol eliminated the compensatory growth.It seems that, the more the shoot growth is inhibited, the more significantly the compensatory growth is registered.

Key words: Sweet cherry trees, Paclobutrazol, Chemical control, Flower 1ud differentiation
