光补偿点的英文
light compensation point
例句与用法
- Light compensation point
光补偿点 - The special species s . platensis in inner mongolia has the highest value of the content of pigments , the biggest net photosynthetic rate , the highest lightcom - pensation and lightsaturation . has the lowest value of the respiration ( 24 )
内蒙古特有的钝顶螺旋藻s1的光合色素含量、最大净光合速率、光补偿点、光饱和点都最高，呼吸速率最低（ 24 ） 。 - The results show : ( 1 ) the light compensation point and light saturation point of s1 s2 and s3 were in range of 12 ~ 27 mol / m2 s and 180 ~ 360 mol / m2 s , respectively , and they changed with the irradiance . ( 2 ) both light compensation point and light saturation point of s1 were higher than those of s2 and 83 , and s1 showed greater capability against high irradiance than s2 and s3 . ( 3 ) the optimal temperature of the three strains were 25 , 35 and 30 , respectively , and they had temporal effect . ( 4 ) respiratory rate rose as the temperature rising , and at about 40 , it reached the peak
结果表明： ( 1 ) s _ 1 、 s _ 2 、 s _ 3的光补偿点和光饱和点的变化范围分别为12 27 mol m ~ 2 ? s和144 360 mol m ~ 2 ? s ，二者可随光照环境的变化而变化，其中s _ 1的光补偿点和光饱和点均高于s _ 2和s _ 3 ，且表现出强于其余两个藻种的抵御强光辐射的能力； ( 2 )三个藻种的最适温度分别为25 ， 35 ，和30 ，具有时间效应； ( 3 )呼吸速率随温度的升高而升高，最大值出现在40附近；温度低于25 ， s _ 1的光合速率最高，呼吸速率最低，表现出很强的低温适应性； ( 4 )螺旋藻的光合特性可随光照环境的变化而变化，光强增强，可使螺旋藻的最适光照范围增大，抵御强辐射的能力增强； ( 5 )螺旋藻受到温度胁迫时，其最适光照范围变窄，对光强的敏感性增加。 - The light saturation points , compensation points and dark respiration rates of t . media cv . hicksii seedlings go down while the contents of chlorophyll and the ratios of chlorophyll a and b increase along with the weakening of light intensity of the growing environment , but their co2 compensation points and photorespiration rates go up
遮荫使曼地亚红豆杉幼苗光饱和点、光补偿点及暗呼吸速率降低，但光呼吸速率和co _ 2补偿点升高，叶绿素含量增大而叶绿素a b减小。
