• 叶绿素

  Poor light resulted in lower SLW,photosynthetic rate,chlorophyl a/b ratio,and higher LAI. And the more the shading,the lower photosynthetic ability and yield were.

  田间光照不足导致大豆叶面积指数增加，比叶重减小，光合速率和叶绿素a／b值降低，且荫蔽越严重，光合能力越弱，产量越低。

生物学

• 叶绿素

  At the same time, the concentration of chlorophyl a and b increase significantly in the leaves of Broussonetia papyrifera seedlings.

  同时构树幼苗叶绿素a和叶绿素b的含量显著增加,进而净光合速率增加。
