low irradiance中文什么意思
例句与用法
- Generally speaking , leaf nitrogen content per unit leaf area increased under high irradiance and was significantly higher than those under low irradiance
损伤处理可使植株叶单位叶面积n含量降低，而单位叶重n含量却比未受损植株高。 - For the factor of light intensity , three light intensities were applied : full irradiance ( 100 % ) , intermediate irradiance ( 43 . 5 % ) and low irradiance ( 6 . 74 % ) ; for the factor of leaf loss , plants were given defoliation ( 70 % of total leaves removed ) and non - defoliation treatment
光照强度设置了3个光照水平：全光照( 100 ) 、中度光照( 43 . 5 )和低光照( 6 . 74 ) ；叶损失处理设置了70去叶处理和未去叶处理两个水平。 - Plants partitioned more biomass to the underground parts at high irradiance and more biomass to leaves at low irradiance . biomass partitioned to roots and leaves of plants at intermediate irradiance went between those of plants at high and low irradiance . defoliation of plants led to an increased partitioning of biomass to leaves , but the results were different at different time
总体来说，在高光照水平下，植株加大了对根的生物量分配，在低光照水平下增加了对叶的生物量分配，中度光照条件下植株对根和叶的分配则处于两者之间；叶组织损失使植株加大了对叶的生物量投资，不同处理阶段结果有所不同；在低光照条件下，叶损失植株对叶的生物量分配显著高于高光照下的叶损失植株。 - The temperature stress made the cells optimal irradiance range narrow and also made their sensitivity to irradiance . study on the daily variation of photosynthesis in different weather in four seasons in a year was carried out , too . the results showed that the daily variation curves of s1 , s2 and s3 were two - peak curves in high irradiance , and the higher the irradiance was , the earlier the first peak appeared . in the weather with low irradiance ( for example , in cloudy day ) , the photosynthetic rate varied with the irradiance changing
四季温室不同天气(晴天、多云天气和阴天)螺旋藻光合速率日变化测定结果显示，在光照较强的天气(如晴天) ， s _ 1 、 s _ 2和s _ 3的光合速率日变化曲线呈双峰曲线，且光照越强，峰值出现越早；在光强较弱的天气，光合速率随光强的升降而升降。 - The quantity of increased leaf efficiency contributed to the aboveground biomass gain after defoliated are different at different irradiance . at the initial stage , the increased leaf efficiency of defoliated plants contributed more to biomass increment of aboveground under higher light level than those under lower irradiance . as the treatment time extended , the contribution to growth of increased leaf efficiency of plants under intermediate light level went beyond those under full irradiancy
( 2 )叶受损的植株叶效率显著高于未受损植株；光照强度越高，植株的叶效率越高；受损植株增加的叶效率在不同光照条件下对生长的贡献大小不同，处理初期，全光照下叶损失植株增加叶效率对地上部分的生物量增加贡献大于中度光照，大于低光照下植株，随处理时间的延长，中度光照下的植株增加叶效率对生长的贡献逐渐超过了全光照下植株。
