【摘要】 本试验观测了生长季修剪和环剥对藤稔葡萄果实生长发育动态及叶片光合作用的影响。结果表明 ,修剪和环剥促进了果实的生长发育 ,果肉细胞体积、果实纵横径、干鲜重均显著增加 ;糖酸含量的变化速率也明显加快。环剥对果实发育前期的促进作用更为显著。生长季修剪对叶片的光合作用有良好影响 ,不仅增加了叶绿素的含量 ,还提高了光合速率、气孔导度 ;而环剥的影响恰与之相反。通过分析还发现 ,环剥和对照植株叶片光合中午降低时发生了非气孔限制更多还原

【Abstract】 Effects of pruning and girdling in growth season on the variation of fruit development and leaf photosynthesis of’Fujiminori’grape were studied in this experiment. The result proved that fruit growth was promoted,that is to say, cell volume , fresh weight ,dry weight ,length ,diameter of fruit were all promoted with pruning and girdling; variation of sugar and acid contents were also promoted . Fruit development was promoted by girdling in earlier stage more significantly. Pruning in growth season has good effects on photosynthesis of leaf,as a result ,content of chlorophyll was increased , photosynthesis rate and stomatal conductance were advanced; while girdling has adverse effects. After analyzing, we also find that in occurred non-stomatol limitatio in leaf on girdled and controlled shoot while photosynthesis of leaf dropped in noon.更多还原
