1·The upper leaves are smaller and with lower photosynthetic rate.
上部叶片较小且光合速率较低。
2·Decreased relative humidity induces decreased net photosynthetic rate.
相对湿度降低，净光合速率也降低。
3·The result showed: In water stress, the Pn (photosynthetic rate) decreased.
结果表明，水分胁迫使欧李光合速率下降。
4·Photosynthetic rate of tulip behaved linearity decreased in anaphase of tulips.
郁金香后期光合速率呈线性陡降。
5·The net photosynthetic rate was in accord with both stomatal conductance and water potential.
净光合率的提高与气孔导度及水势的提高有一致趋势。
6·The peanut treated with BN could increase LAI and photosynthetic rate, which provided high yield.
喷施BN可以增大花生叶面积指数，提高光合效率，为花生高产奠定基础。
7·After plant infect with the virus, a photosynthetic rate of leaf of different leaf-age will lower.
植株感染病毒后，不同叶龄的叶片光合速率都会降低。
8·The photosynthetic rate and excretory ability affected the nitrogenase activity in the rhizosphere.
水稻的光合作用及报分泌能力影响根际固氮活性。
9·With proper rate of sulphur fertilizer application, the photosynthetic rate of soybean was increased.
适当的施用硫肥能提高大豆光合作用强度。
10·Low temperature and low light intensity were limited factors for photosynthetic rate in leaves of Panax ginseng.
低温和低光照强度均可成为人参叶片光合速率的限制因子。
