光合能力 meaning in English
photosynthetic capacity
Examples
- Leaf area is the best measure of the photosynthesizing capacity of the plant .
叶面积是测定植株光合能力的最好尺度。 - The experimental results showed that chlorophyll content and photosynthetic rate of irrigated sugarbeet seedlings were increased under the drouthy springtime , especially high photosynthesis of leaf was kept during growth anaphase
摘要春季干旱条件下，苗期灌溉处理可以提高甜菜叶片叶绿素含量和光合速率，尤其对于生育后期保持叶片较高的光合能力有明显作用。 - When inadequate n was added , the chloroplast structure in mesophyll cell was damaged in ear leaf , the amount of carbohydrate decreased in mestome sheath , and excessive n - redistribution and n - transportation to grain from vegetative mass appeared , which resulted in earlier leaf senescence . excessive n application led to too high activity of nitrate reductase , excessive vigorous nitrogen metabolism and too much exhaustion of carbohydrate in ear leaf , which resulted in the lack of enough carbohydrate in the lower leaf , meanwhile , the expansive chloroplast grana lamellae in leaf mesophyll cell and starch grain without nuclear in mestome sheath cell was observed , which led to the decrease of chlorophyll content and photosythetic capacity in maize leaf , then the early senescence occured
氮肥用量不足导致穗叶叶肉细胞叶绿体结构性差，维管束鞘细胞碳水化合物累积减少,营养体氮素再分配率大而引起叶片早衰；而过量供氮则导致生长后期硝酸还原酶活性过高，氮素代谢过旺，消耗了大量碳水化合物，以致下位叶不能得到充足的碳水化合物供应而提早脱落，同时叶肉细胞叶绿体片层结构膨胀，呈“肉汁化”特征，维管束鞘细胞淀粉粒大量消耗，无核淀粉粒出现，从而叶片叶绿素含量下降，光合能力降低而出现早衰。 - Compared with common methods for measuring the photosynthesis rate based on consumption of co2 , the technique in this thesis can be used to quantify the plant photosynthesis capability with less interferences of the environment . we thus conclude that df is an excellent indicator for evaluating plant photosynthesis ability under its biological status
研究结果表明:植物叶片延迟荧光强度和现有的便携式光合速率测定仪在实验室条件下测得的光合速率具有很好的相关性，能较真实的反映植物在所处生理条件下的光合能力。 - In the ranges of high light , pn of cydobalanopsis multinervis was higher under full light treatment and pn of michelia foveolta was higher under one layer shading . 2 . photosynthetic diurnal variation of cydobalanopsis multinervis and michelia foveolta under different shadings . the curves of photosynthetic diurnal variation were changed by shading in cyclobalanopsis multinervis and michelia foveolta , pn of cyclobalanopsis multinervis was decreased obviously during daytime
就光响应曲线而言，低光强范围内遮荫处理的2树种幼苗表现出较强的光合能力，在较高光强范围内，多脉青冈在全光照处理下的净光合速率有明显优势，而金叶含笑在一层遮荫处理下的净光合速率较高。
