“早生旭”苹果的大枝,将其上的花在开花前全部琉除,或全部保留,在花后综合施用BA50mg·l~(-1)或B9 2000mg·l~(-1)。BA和琉果增加连续开花的能力,而B9无效。投有那个处理对短枝叶面积有稳定的效果。“元帅”苹果在盛花后5、14和22天重复喷布GA_(4+7)可使短枝内的附属物发育和花芽形成减少。在盛花后42夭喷布一次GA_(4+7) 150mg·l~(-1)可减少短枝附属物形成和开花百分率,但其效应不如早期反复喷布GA_(4+7) 50mg·~(-1)那样显著。在盛花后42天喷布GA_(4+7)时加上BA150mg·l~(-1)可以增加附属物形成,但不能扭转成花下降的情况。“旭”苹果树在盛花后22天喷布BA50mg·l~(-1)可增加附属物形成的数目,但不影响连续开花能力。
“Early Asahi ” big branch of apple, the flowers on the flowers before flowering in addition to all, or all retained after the combined application of BA50mg l ~ (-1) or B9 2000mg l (-1). BA and fruiting bodies increase the ability of continuous flowering, while B9 is ineffective. There is a stabilizing effect on the area of short branches and leaves. “Marshal ” Apple repeats spraying GA 4 (4 + 7) 5, 14 and 22 days after flowering can reduce appendage development and flower bud formation in the spur. After 42 days of full bloom, GA 4 (4) 7 and 150 mg · L -1 could reduce the formation and flowering percentage of spur appendages, but the effect was not as good as that of GA 4 (4 + 7) 50mg · ~ (-1) as significant. Spraying GA_ (4 + 7) at 42 days after flowering added BA150mg · l ~ (-1) to increase appendages, but did not reverse the decline of flowering. “Asahi ” apple trees sprayed with BA50mg · l ~ (-1) at 22 days after flowering increased the number of appendages formation, but did not affect the continuous flowering ability.
