1) Midday rest
光午休
2) midday depression
光合午休
1.
The re- sults indicated that hybrid F_1 had lower lipid peroxidation degree,higer activity of scavenging active oxygen,and lower degree of midday depression of photosynthesis,as was compared with its parents.
对冬小麦生育后期 F_1个体的杂种优势进行了研究,初步表明旗叶叶片衰老时,膜脂过氧化程度较低,内源活性氧清除系统仍维持较高活性,以及光合午休程度较低是 F_1杂种优势的两个生理表现。
3) Midday depression of photosynthesis
光合午休
1.
The results showed that:(1)There was typical midday depression of photosynthesis but no photoinhibition phenomenon or cotton leaves both in moist condition and in arid condition.
结果表明:(1)不同土壤水分条件下棉花叶片均出现"光合午休"现象,但均未出现光抑制;干旱条件下引起棉花"光合午休"以非气孔因素为主,湿润条件下非气孔因素和气孔因素先后共同起作用。
4) midday depression
午休
1.
The curve of diurnal net photosynthetic rate(Pn) variation of Yingshuang had two peaks and its obvious phenomenon of midday depression was the circadian representation.
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。
5) midday depression of photosynthesis
午休
1.
It was found that during the tested 4 growing stages, the Pn of F 1 showed a curvilinear change with one peak without midday depression of photosynthesis.
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.
But the internal leaf CO_2 pressure increased instead of decreasing and the stomatal limitation decreased during the time of midday depression of photosynthesis.
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。
6) take one's nooning
吃午餐;午休
