Effects of Leaf Picking and Paving Reflecting Film on Photosynthetic Characteristics of Leaves in Setting Fruit Position in Cabernet sauvignon Grapes
摘要
Abstract
[Objective] The aim was to study the effect of picking leaves,paving reflecting film and leaf picking combined with paving reflecting film on photosynthetic characteristics of leaves of Cabernet sauvignon grapes. [Method] With 7-year-old C. sauvignon grapes as the test materials,3 treatments of picking the leaves around the fruit,paving the silver reflecting film and leaf picking combined with paving reflecting film were set up and the conventional management plants were taken as the CK. The leaf photosynthetic rate (Pn),stomatal conductance (Gs),intercellular CO2 concn(Ci). and light intensity of 4 treatments were measured,resp.. [Result] The treatments of picking leaves and paving reflecting film all increased the Pn of leaves in setting fruit position of grapes. Compared with CK,Pn of leaves with picking leaf treatment was increased by 28.3%,and that with paving reflecting film treatment was increased by 72.6%. Compared with the treatment of paving reflecting film or picking leaves,there was no significant additive effect with paving film + picking leaves treatment. There was a certain influence of paving reflecting film and picking leaves treatment on leaf Gs and the effect of picking leaves was great. There were some differences on the Ci. of leaves at different times in all treatments. [Conclusion] In general,paving reflecting film had a better effect than that of leaf picking.关键词
