添加佐剂对CPPU处理的翠冠梨果实生长与品质的影响

为了减少CPPU引起的不良效应,探讨了在CPPU溶液中添加不同佐剂对翠冠梨果实生长及品质的影响。结果表明,盛花后第2周用20mg/L CPPU处理可以促进果实膨大,提高单果质量,并延迟果实成熟。CPPU单独处理增加畸形果比率,而添加0.1% Triton或者PVAC作为佐剂则可减少畸形果的发生,并增强CPPU处理效应,因此,在CPPU使用过程中不应忽视佐剂的作用。

Effects of CPPU with supplementary agent on the growth and fruit quality of Cuiguan pear cultivar

It has been reported that CPPU induces malformation in part of fruit when it was used to promote fruit enlargement. In order to eliminate the by-effect of CPPU,various supplemental agents were added to CPPU solution to test their effects on fruit growth and quality of Cuiguan pear cultivar (Pyrus Pyrifolia Nakai cv. Cuiguan). The results showed that fruit growth was promoted in heavier weight and later maturation by 20 mg/L CPPU treatment 2 weeks after full bloom. It is suggested that CPPU treatment prolonged fruit expansion period,which resulted in maturation delayed. CPPU treatment increased the malformed fruit percentage,but,if suitable agents such as 0.1% Triton or PVAC added the malformed effect was dramatically decreased and the promotion on fruit growth became further significant,implying that the role of agents in CPPU application should be paid more attention to.
