关于棉株不同年龄,不同部分及几种不同情况下的光合强度以及棉叶对光照条件的适应问题,我们曾作过初步报导[1、2]。本文拟进一步对棉株光合性能有关的几个指标加以分析探讨。研究工作主要是在1959及1960年进行的,研究的棉花品种仍为岱字15号,测定净光合及呼吸强度的方法仍为稍加修改的 pH 指示剂法[1、2]。
We have made preliminary reports about the photosynthetic intensity of cotton plants at different ages, different parts and several different situations, and the adaptation of cotton leaves to light conditions [1,2]. In this paper, we will further analyze the photosynthetic performance of cotton plants related to several indicators. The research work was mainly carried out in 1959 and 1960, and the cotton variety under study was Dai Dai No.15. The method of measuring net photosynthesis and respiration intensity is still a slightly modified pH indicator method [1,2].
