苹果树上用植物生长调节剂控制营养生长常对果实有不利影响,并需高剂量。PP333是一种强烈的营养生长延缓剂,但它有效减弱生长的剂量并不明显抑制果实的生长。与 B9和CCC不同,PP333灌施于土壤,施用于主部或注射到树体均有效,而叶面喷施则无效。 PP333对植物有长期效应,其所引起
Apple trees with plant growth regulators to control vegetative growth often adversely affect the fruit, and the need for high doses. PP333 is a strong growth retardants, but its effective dose to reduce growth does not significantly inhibit fruit growth. Unlike B9 and CCC, PP333 is applied to the soil, applied to the host or injected into the tree, and foliar spray is ineffective. PP333 has a long-term effect on the plant which causes it
