据《Hort Science》(2012年11月)的一篇研究报道,来自麻省大学的研究人员评估了脱落酸(ABA)和ABA结合苄基腺嘌呤(BA)对巴特利特(Bartlett)梨的疏果效果。开花期、谢花期和果实直径10mm时施用ABA500mg/L都能起到明显的疏果作用,果实直径10mm时施用几乎全部落果。研究人员还评价了A-BA50mg/L和500mg/L在果实直径10mm时施用的疏果效果,结果呈二次分布并高度显著。50mg/ABA也能起到疏果作用。果实直径10mm时BA
According to a study by Hort Science (November 2012), researchers at the University of Massachusetts evaluated the effect of abscisic acid (ABA) and ABA in combination with benzyl adenine (BA) on Bartlett pear Thinning effect. Flowering, flowering, and fruit diameter of 10mm ABA 500mg / L can play a significant role in thinning fruit, fruit diameter of 10mm when applied almost all fruit drop. The researchers also evaluated the thinning effect of A-BA at 50 mg / L and 500 mg / L at a fruit diameter of 10 mm, with secondary and highly significant results. 50mg / ABA can also play a role in thinning fruit. Fruit diameter 10mm BA
