5个品种光合日变化表明,浙农139与乌牛早、龙井43在8:00-14:00的光合速率有极显著的差异;净光合速率的日变化出现单峰型和双峰型,迎霜呈双峰型日变化,其出现午休的现象是茶树自身生理节奏的体现;在弱光高温环境下,温度在35℃以上时茶树的光合作用受到抑制,这种抑制是温度影响下的气孔限制和非气孔限制共同作用的结果。
3) midday depression of photosynthesis
午休
1.

利用Li 64 0 0光合测定系统对抗虫杂交棉鲁棉 1 5号杂种 (F1)及其父本 (M)、母本 (F)光合日变化的研究表明 ,F1的光合日变化在测定的 4个生育阶段皆呈单峰曲线 ,未出现午休 ,其净光合速率 (Pn)在铃期前一直高于M和F ,铃期界于M和F之间 ,表现出极强的光合能力 ,这是杂种F1生长势强、产量高的重要生理基础。
2.

实验结果表明,大豆叶片的光合午休现象主要是因为大豆叶片的羧化效率、光合能力,RUBP再生能力的下降以及CO_2补偿点升高造成的。
