CPPU对温州蜜柑着果和果实品质的影响

CPPU不同浓度和处理时期对尾张温州蜜柑着果有显著影响,以CPPU5mg/L在尾张温州蜜柑谢花后处理的着果率显著高于对照和CPPU20mg/L处理,而与CPPU10mg/L处理差异不显著。CPPU5mg/L在谢花后处理的单果重和可溶性固形物含量与对照差异不显著,果皮较薄。CPPU10mg/L在谢花后处理的着果率高于第一次生理落果结束时的处理,单果重显著重于对照,可溶性固形物含量与对照差异不显著。

Effect of CPPU on Fruit Setting and Fruit Quality of Owari Unshǔ

Effect of different treatment in concentration and period of CPPU on fruit-setting of Owari unshǔwas ob served.The setting rate under treatment of5mg /L of CPPU after withering of flowers was markedly higher than con trol and treatment of20mg /L of CPPU,but the difference between treatment of5mg /L and10mg /L of CPPU was not remarkable.There were no significant differences of per fruit weight and soluble solids between treatment of5mg /L of CPPU after withering of flow ers and on the con trast,the fruit peel was thinner.The setting rate under treatment of10mg /L of CPPU after withering of flowers was higher than treatment after the first physio logical pre mature drop and the per fruit weight was significantly high er than control.But the content of soluble solids between the treatment and control had no significant differences.
