| 2. | The effects of mj on chlorophyll a and chlorophyll b had the same trend as the chlorophyll content . 2
Mj对苹果叶片中叶绿素a 、叶绿素b和叶绿素总量的影响趋势一致，促进叶绿素a的降解程度比叶绿素b明显。 |
| 3. | Soz fumigation shifted the maximal absorbance peak of chlorophyll a from 677 . 7 nm to 672 . 1 nm and the maximal fluorescence peak of chlorophyll b from 667
So2熏气处理引起qp / tch1 、 etr tch1首先上升，处理30天左右以后处理开始下降，到处理100天时其下降达到最大。 |
| 4. | Enhanced uv - b radiation greatly decreased the content of photosynthetic pigments : chlorophyll a , chlorophyll b , and total chlorophyll . supplemental uv - b radiation induced the antioxidant system change
Uv - b明显降低紫萍光合作用色素(叶绿素a 、叶绿素b及总叶绿素)含量，这将导致光合作用下降。 |
| 5. | The content of chlorophyll ( chlorophyll a and chlorophyll b ) , photosynthesis rate , transpiration rate , intercellular co2 concentrations , and stomatal conductance was all reduced under water stress at different development stages
不同生育时期水分胁迫下使叶绿素含量、光合速率、蒸腾速率、细胞间隙co2浓度、气孔导度都有不同程度降低。 |
| 6. | 3 : chlorophyll content : low - temperature can restrain the biosynthsis of chlorophyll and destroy its structure . the contents of chlorophyll a , chlorophyll b and chlorophyll a + b in controls were significantly lower than in transgenic seedlings . the ratio of chlorophyll a / b had the similar result
低温处理后，对照中叶绿素a 、叶绿素b 、叶绿素a + b总含量均显著低于转基因苗，叶绿素a b的比值反映叶绿体中类囊体膜的垛叠程度，对照的叶绿素a b的比值低于转基因苗。 |
| 7. | Both reduced irradiance and defoliation caused decreased slm ( specific leaf mass ) . ( 4 ) generally , chlorophyll content and chlorophyll concentration increased with reduced light levels , the ratio of chlorophyll a to chlorophyll b of defoliated plants was higher than those of controlled plants , while in latter period , the results were contrary to that of the former period
( 4 )叶绿素含量和浓度总体上都随光照水平的降低而升高，叶绿素a / b在高光条件下显著大于低光水平下的植株，叶损失植株的叶绿素a / b值处理初期小于未受损植株，处理后期则大于未受损植株。 |
| 8. | Elevated [ co2 ] treatment resulted in the larger accumulation of carbohydrate ( soluble sugar and starch ) in leaves of anthurium andraeanum lind during short - term experiment , but the difference of three treatment groups is no striking during long - term experiment . chlorophyll content , chlorophyll a / chlorophyll b ratio in leaves increased , while soluble protein decreased in elevated [ co2 ] during experiments . elevated [ co2 ] led to the increase of rubp carboxylase activity and the decline of glycolic acid oxidase activity during short - term experiment , but the rubp carboxylase activity decreased after 60 d , the glycolic acid oxidase activity increased after 90 d
高浓度co _ 2处理的红掌，叶片中的叶绿素含量增加，叶绿素a叶绿素b升高，但可溶性蛋白含量下降，并且随着处理时间的延长，可溶性蛋白含量的下降更为明显，处理150d时， t1 、 t2的可溶性蛋白含量与ck相比分别下降了36 . 7 、 28 . 2 ；高浓度co :处理的前30d ，高浓度c02抑制了go活性， rubpc活性升高:处理以记时，高浓度coz处理组的rubpc活性降低， go活性仍然低于对照;处理以月后，高浓度co :处理组的rubpc活性低于对照，其中t2的rubpc活性显著下降，而go活性升高。 |
