库源调节对油茶叶片碳水化合物含量及其酶活性的影响
Effects of Sink-source Manipulation on Carbohydrate Content and Enzyme Activity of Camellia oleifera Leaves
摘要
Abstract
By means of changing leaf-fruit ratio, the effects of sink-source manipulation on soluble sugar, starch content and enzyme activities with 5-year-old Camellia oleifera were studied. The results showed that a signif-icant increase in soluble sugar and starch content was found in no fruit group(T1),but its related enzymes activi-ties was significantly lower than those in other groups. The soluble sugar and starch content increased slightly with the improvement of remained leaf number and showed a positive correlation. Activities of sucrose synthase (SS), sucrose phosphate synthase (SPS) had a single-peak curve and reached a maximum at T3, T4group respectively. Meanwhile,the invertase and starch phosphorylase increased gradually with the increasing of source and sink. The research showed that the carbohydrate content and its enzyme activities in C.oleifera leaves was affected remarkably when the sink-source relationship was changed. Whereas, the leaf-fruit ratio that could improve the single fruit weight,seed-producing percentage and fruit yield needed to be further studied.关键词
