4个椰子品种光合、蒸腾作用日变化特征及影响因素
Daily Changes of Photosynthesis and Transpiration Rate of Four Cultivars of Coconut and the Influencing Factors
摘要
Abstract
Yellow Dwarf Coconut, Aromatic Dwarf Coconut, Hainan Tall Coconut and Wenye 78F1 at the stage of active fruiting were used as the research materials. The daily changes of transpiration rate, net photosynthesis rate and the interaction of influencing factors as temperature, humidity, intensity of illumination, CO2 concentration were studied. The result revealed that the net photosynthesis rate and transpiration rate of different varieties were with similar two-peak changing tendency, Hainan Tall Coconut with higher transpiration rate and net photosynthesis rate than Aromatic Dwarf Coconut and Wenye 78F1, Yellow Dwarf Coconut with the lowest values compared to the others. The eonelation analysis revealed that the net photosynthesis rate was mainly influenced by the intensity of illumination and leaf temperature. Air humidity and leaf temperature were the main factors that affected the transpiration rate.关键词
