环剥处理对'金艳'猕猴桃叶片和果实的影响
Effects of Different Girdling Treatments on Leaf and Fruit of'Jinyan'Kiwifruit
摘要
Abstract
[Objective]The effects of different girdling treatments on photosynthetic characteristics,physiological and biochemical indexes of kiwifruit leaves,fruit yield and quality were explored,in order to screen suitable girdling method.[Method]'Jinyan' kiwifruit was used as the test material,single-layer 360° and double-layer 240° girdling with width of 5 mm and 9 mm were carried out at the rapid ex-pansion period(10 days after flowering)and the rapid dry matter accumulation stage(80 days after flow-ering)of 'Jinyan',and no girdling was used as the control(CK).The photosynthetic characteristics of leaves at 35 days after girdling and the leaf physiological and biochemical indexes,fruit yield and quality at fruit ripening stage were measured,and the principal component analysis method was used to compre-hensively evaluate different girdling treatments.[Result]Girdling could significantly reduce the net photosynthetic rate,stomatal conductance and transpiration rate of 'Jinyan' kiwifruit leaves,increase the intercellular CO2 concentration and the contents of soluble protein,soluble sugar and soluble starch in leaves.Twice girdling could further deepen the negative feedback on leaf photosynthesis.All treatments increased the yield per plant and single fruit weight to varying degrees,especially T7,T8,and T4.T7,T6 and T5 significantly increased the soluble solids and dry matter content of fruit by 11.92%-15.62%and 7.92%-12.10%,respectively.Except T1,T2 and T8,other treatments significantly increased the ascorbic acid content of fruit by 5.56%-13.89%,with T6 being the highest,followed by T7.[Conclusion]Twice girdling at 10 d and 80 d after anthesis could provide sufficient nutritional guarantee for the growth and development of 'Jinyan' kiwifruit at different key stages,promote the utilization of car-bohydrates in fruit,and improve fruit yield and quality.T7 had the best effect on improving quality and increasing yield.关键词
