摘要
随光量子流密度由低到高的变化,西洋参CO_2同化率曲线呈现为3个阶段,具有明显的光抑制现象。西洋参的光饱和点为90μmolm^(-2)s^(-1)。4小时以内的强光照对西洋参光合CO_2同化率的抑制是可以恢复的。本文对山区西洋参生产中的光合潜力问题进行了讨论。
With the variation of photon flux density from low to high, the curves of co_2 assimination rate show three parts in Panax Quinque folium. It has obvious light inhition. Its light saturation point is 90 μmolm^(-2)s^(-1). The inhibition of co_2 assimination rate could return if the time of strong light shining is less than four hours. The dcvelpment of photosynthetic potentiality has been disscusscd on the products of P.Quinqur folium in mountains.
