1) 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。
2) 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。
3) take one's nooning
吃午餐;午休
4) 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。
5) midday depression
午休现象
1.
The feedback response of stomata to the change of environmental humidity could be used to explain the midday depression of stomatal c.
气孔对环境湿度变化响应的反馈机制可用来解释土壤干旱条件下气孔和光合的午休现象,以及气孔导度和水流导度之间的相关关系;而气孔对环境湿度变化响应的前馈机制,则可用来解释气孔导度对大气-叶片间水汽饱和差的滞后反应。
