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。 In order to reduce the adverse effects caused by CPPU, the effects of adding different adjuvants to CPPU solution on the growth and quality of Cuiguan pear were also discussed. The results showed that treatment with 20 mg / L CPPU for 2 weeks after full bloom promoted fruit enlargement, improved fruit quality and delayed fruit ripening. CPPU alone increased the rate of abnormal fruit, and add 0.1% Triton or PVAC as adjuvant can reduce the occurrence of abnormal fruit, and enhance the CPPU treatment effect, therefore, should not be ignored in the use of CPPU adjuvant role.
