摘要
通过对百棉1号、中棉所41、新棉99B和鲁棉研21共4个棉花栽培品种的光合速率、气孔限制值、水分利用率、光响应曲线及相关参数研究,得出结论:棉花的光合作用没有午休现象,具有较高的光合速率、光饱和点,较低的光补偿点和暗呼吸速率,且光合速率不受气孔因素的影响,从而为棉花提供较多的物质积累而高产稳产。
Abstract
Photosynthetic rate, stomata limit value, water use efficiency, response curve of light and relevant parameter of four cotton cultivars were studied in this paper. The results indicated that there were high photosynthetic rate and light satu- ration point, with low light compensation point and dark respiration rate during cotton photosynthesis. "Noon Break" phenome- non did not exist at all. In the other hand, photosynthesis which can provide abundant matter accumulation for high and stable yield of cotton could not be influenced by the stomata limit value.
