查询词典 photosynthesis

High temperatures may lead to enzyme inactivation or the unbalancing of components of metabolism; for example, in plants, respiration may proceed faster than photosynthesis, leading to death, however, the most frequent effect of high temperature on ectotherms is dehydration.

此外，植物体内C/N平衡、生长调节物质和己糖激酶对光合基因表达水平的调控等多个方面也会对光合适应产生影响。

Photosynthetic physiology index and diurnal change of photosynthesis, in 5 Rhododendron delavayi cultivars, such as jean de marle montague, Bule bell, which were introduced from Shijiazhuang, Hebei Province were studied. The photosynthetic light -response curve of different cultivars was also simulated.

H and M c are wetter than middle soil water content, belongs to mesophytes; The optimal water niche of Mosla scabra, on photosynthesis is more wetter than that of M.h and Me, the optimal water niche between mesophytes and hygrophytes, and leaning to hygrophytes; The photosynthetic water condition of M.d is arid environments, and its ecotype exits between mesophytes and xerophytes, and leaning to xerophytes.5 M.h and M.s are locating between shade plants and sun plants, while M.c and M.d obviously belong to sun plants.

杭州石荠苧与华荠苧光合的最适水分条件是中等偏湿，其水分生态类型应属于中生植物；石荠苧光合的最适水分条件比杭州石荠苧与华荠苧光合的最适水分条件要求更湿，其水分生态类型介于中生和湿生植物之间，更偏向湿生；小鱼仙草光合作用的水分生态条件是干旱条件，其水分生态类型介于中生与旱生植物之间，更偏向旱生。

The results showed that mild alkali stress (pH 6.0~6.5) promoted plant growth, while severe high pH inhibited both seed germination, photosynthesis and root elongation.

结果表明：pH值过高会抑制种子萌发；随着pH值的逐渐增加，根的相对生长量和幼苗叶绿素含量均呈现先增加后减少的趋势；同时，根尖生长素含量随着pH值升高呈现先增加后减少的趋势，表明生长素含量变化可能在植物对碱胁迫的响应中，尤其是在根伸长过程中起着重要作用。
