本试验就喷施多种植物生长调节剂对番茄畸形果发生的影响进行了研究，结果认为：ＧＡ３、Ｂ－９、乙烯利３种植物生长调节剂不仅显著地提高了番茄畸形果（尤其是乱形果中顶裂果、混发果）的发生率，而且还加重了畸形果的发生程度及增加了畸形果的类型。其中ＧＡ３的影响最大，Ｂ－９次之，乙烯利的作用较小。２，４－Ｄ和ＰＣＰＡ则显著地降低了畸形果的发生类型和发生程度。ＰＰ３３３有减轻畸形果发生的趋势。在本试验的施用浓度下，ＩＡＡ、ＮＡＡ、ＢＡ、ＣＣＣ等４种植物生长调节剂对番茄畸形果的发生无显著作用。
In this study, the effects of spraying a variety of plant growth regulators on the occurrence of tomato malformations were studied. The results showed that GA3, B-9 and ethephon not only significantly increased tomato malformations (especially Chaos-shaped fruit in the top of the crack, mixed fruit) the incidence, but also increased the incidence of deformities and increased the type of deformed fruit. Which GA3 the greatest impact, B-9 times, the role of ethephon smaller. 2,4-D and PCPA significantly reduced the incidence of deformities and the degree of occurrence. PP333 has the tendency to reduce the occurrence of deformities. In this experiment, four plant growth regulators, IAA, NAA, BA and CCC, had no significant effect on tomato malformation.
