- 摘要:
- 选用改良丰产剂2号与在薄皮甜瓜上常用的防落素、吡效隆以及丰产剂2号进行比较试验,测定薄皮甜瓜的坐果率、产量、畸形果发生率及成熟果实中可溶性糖、有机酸和维生素C含量,并进行方差分析。结果表明:在薄皮甜瓜坐果率、前期产量、总产量和平均单果重方面,改良丰产剂2号不仅极显著地高于对照,而且高于防落素、吡效隆和丰产剂2号;在畸形果发生率方面,改良丰产剂2号低于吡效隆和防落素,高于对照和丰产剂2号;在品质方面,改良丰产剂2号处理的薄皮甜瓜果实可溶性糖含量高于其它处理,维生素C含量高于防落素、吡效隆和对照,有机酸含量高于吡效隆和对照。
- Abstract:
- A comparing experiment of several plant growth regulators was engaged. The improved No.2 high-yield agent,selected by formula screening test, was compound plant growth regulator. PCPA and Forchlorfenuron were commonly used for thin-peel melon.The No.2 high-yield agent had perfect application effect on tomato. Several indexes of the thin-peel melon were investigated: fruit setting rate, yield and deformed fruit rate;soluble sugar, organic acids and vitamin C in mature fruit. Analysis of variance of the results was made.The results showed that, in fruit setting rate, early yield, total yield and average weight of single fruit of thin-peel melon, improved No.2 high-yield agent was not only very significantly higher than the control, but also higher than PCPA,Forchlorfenuron and No.2 high-yield agent. In deformed fruit rate, improved No.2 high-yield agent was lower than PCPA and Forchlorfenuron, higher than the control and No.2 high-yield agent. Compared with Forchlorfenuron,deformed fruit rate had a significant reduction. In quality, the improved No.2 high-yield agent treated thin-peel melon had higher soluble sugar content than other treatments; vitamin C content higher than PCPA, Forchlorfenuron and control; organic acids content was higher than Forchlorfenuron and control.
