五十年代初开始茶树光合作用研究以来,光合作用测定技术得到了不断的改进,从田间半叶法和同化箱法发展到室内离体测定法。离体法测定光合作用可以排除田间环境条件差异的影响,利于进行比较研究,然而它却受到离体时间和室内贮放时间差异的影响。不同时间离体的枝条,其内含光合产物不同。法国植物专家Bousigault(1968)认为,照光叶片由于同化产物的积累而使得叶片光合产物下降。离体枝叶在室内贮放过 Since the beginning of the research on the photosynthesis of tea plant in the early 1950s, the determination of photosynthesis has been continuously improved, ranging from the field half-leaf method and the assimilation box method to the in-vitro determination method. In vitro determination of photosynthesis can exclude the impact of differences in field environmental conditions conducive to comparative studies, but it is subject to in vitro and in-house storage time differences. The detached shoots at different times contain different photosynthetic products. Bousigault (1968), a French botanic expert, argues that photosynthetic products in leaves are reduced due to the accumulation of assimilation products. Detached leaves stored in the room too
