Leaf chlorophyll content的意思|示意

Photosynthetic rate and chlorophyll content of flag leaf declined sharply, and leaf stomatal resistance increased rapidly in late period of senescence.

衰老后期，根系活力、叶片光合速率和叶绿素含量快速下降，叶片气孔阻力增加。

The photosynthetic rate is low because of the chlorophyll content of leaf is low in earlier stage;

前期由于叶片叶绿素含量低，光合速率也低；

Chlorophyll content had no significant relation with the net assimilation rate, but was related to the nitrogen content and the specific leaf weight.

叶绿素含量与净同化速率间没有显著关系，但与含氮量和比叶重有关。

Leaf N/ chlorophyll content and SPAD value increased with the increasing N fertilizer, and the lower leaves were more sensitive to the soil N supply than the upper leaves.

下位叶比上位叶对土壤氮的供应状况更为敏感，随着施氮量的增加，水稻叶片氮素含量、叶绿素含量、SPAD值相应的增加，而下位叶的增幅更明显。

With increasing inundation duration, the leaf proline and MDA contents and SOD activity increased after an initial decrease, while the leaf chlorophyll content decreased gradually.

随着淹水时间的增长，脯氨酸含量、MDA含量和SOD活性均先下降后上升，叶绿素含量则逐渐降低。

The content of leaf MDA decreased, but chlorophyll content, photosynthesis rate and stomatal conductance recovered rapidly with leaf stages after imazethapyr spray.

结果表明，随着叶龄的增大，施药后鸭跖草叶中丙二醛（MDA）含量变化量下降，而叶绿素含量、光合速率及气孔导度恢复越快。
