| 摘 要： | 光合作用是植物重要的生理过程之一,是植物物质生长的基础1],对植物生长发育具有重要意义.光合作用的强弱取决于树木的遗传性和环境条件的影响,由于光合作用与树木生长地环境条件的密切关系,光合强度在引种驯化中常作为评价树木适应性的重要指标.树木对某一地区的适应性,是其对该地区各种环境条件的生理生态反应的综合表象.

| Abstract: | The diurnal variation of photosynthesis of Phyllostachys edulis cv.pachyloen was studied by LI-6400,as well as those of photosynthetic photon flux density(PPED),CO2 concentration in air(Ca),relative humidity(RH) and air temperature(Tair) were measured,and the relationships between the diurnal of Pn,Tr and climatic factors were analyzed by correlation coefficient path coefficient and decision coefficient analysis.The results were as follows:in the typical spring sunny days under natural conditions,the curve ... |
