叶绿素

It is said that C〓 alkylthiophene probably originated from fatty acids and C〓 alkylthiophene probably derived from phytol side chain of chlorophyll. The research suggested that fatty acids such palmitic acids transformed into petroleum components more easily at lower temperature than phytol side chain of chlorophyll which transformed massively at 300℃.

据分析C〓烷基-噻吩可能源自脂肪酸，而C〓烷基-噻吩可能源自叶绿素的植醇侧链，这似乎表明，藻细胞中的脂肪酸类比叶绿素的植烷侧链更易于在较低温度下向石油组份转化，而后者在300℃时则大量转化。

The results showed that the NPK2 level increases content of chlorophyll , raises net photosynthesis rate, stomatal conductance and water use efficiency notably and reduce Chl-a/Chl-b ratio, transpiration rate, intercellular CO2 concentration in A. chinensis Planch cv "81-5" leaves.

结果表明，NPK2处理可以增加猕猴桃叶绿素含量，显著提高光合速率、气孔导度和水分利用效率，降低叶绿素a/b值、叶片蒸腾速率和胞间CO2浓度。

The contents of Chla and Car were sensitive to low temperature stress, it seems that they were vulnerable to low temperature stress and partly decomposed. Relatively, the content of Chlb changed little. The ratio of Chla/b had positive linear correlation with temperature, which meant the photosynthetic ability of podocarpus fleuryi Hickel seedlings declined under winter low temperature stress.

叶片中叶绿素a和类胡萝卜素含量对低温胁迫反应较为敏感，容易遭受低温胁迫而部分地分解破坏，含量下降，而叶绿素b则相对变化较小，Chla／b值呈现与温度的线性正相关，显示了长叶竹柏幼苗在冬季低温胁迫下光合能力的下降情况。

There were high positive correlations between activity of root and photosynthetic rate of flag leaf, ZRs content and activity in root, ZRs content and photosynthetic rate in flag leaf respectively.

根系活力的下降速度和叶片的叶绿素下降速度相比，根系活力的下降大于叶绿素的下降，根系活力的衰退先于叶片的功能衰退。

The inner praline and infiltration and adjust matter of soluble sugars small molecule increased.

在盐胁迫下，番茄叶片中叶绿素、Chla和Chlb的含量整体变化呈下降趋势，高盐胁迫下叶绿素a/b值呈上升趋势。

Duchesnea indica、Ranunculus repens、Potentilla flagellaris、Glechoma hederacea have the charactistic of sprouting early in the spring and growing rapidly.

叶片的解剖结构、气孔密度和光合曲线都能很好的反映植物的耐荫性，而叶绿素含量及叶绿素a/b可以作为一个参考指标。

该性状的表达是由于阶段性叶绿素代谢异常所致，它不仅与叶绿素含量有关而且与 POD、CAT、SOD等几种酶活性之间存在一定关系

When the concn. of NaCl was lower than 200 mmol/L, the contents of chlorophyll in saltbush leaves had no significant increment in CK and treatments with Spd and Spd+DCHA and when the concn. of NaCl was 400 mmol/L, their chlorophyll contents were increased significantly.

NaCl浓度低于200 mmol/L时，对照和Spd、Spd+DCHA处理的滨藜叶片中的叶绿素含量增加不显著，NaC l浓度为400 mmol/L时，它们的叶绿素含量增加显著。

Different temperatures, the chlorophyll content of several plant Sedum change, with increasing temperature and chlorophyll content decreased.

不同温度下，几种景天植物的叶绿素含量发生了变化，随着温度的升高叶绿素的含量降低了。

F. pumila had the strongest capacity to adhere to walls, and it formed a quite good covering landscape by means of a large quantity of adventitious roots. Furthermore, it was tolerant to shade, and the effects of shading on its growth and landscape covering were very small. P. heterophylla had the rapidest growth and covering speed, and it adhered to walls by adhesive discs, but was defoliated in winter or after a long period of shading. The other three vines climbed walls using adventitious roots, and their adhering capacities were all relatively poor. However, E. fortunei still formed a relatively good covering due to its rapid growth and emerald leaf colour. After shading for four months, leaves of F, pumila, C. grandiflora, and P. serpens became thin, and accordingly their leaf weight per unit area significantly decreased. Shading also reduced chlorophyll contents of C. grandiflora and E. fortunei but enhanced those of F. pumila and P. serpens, It did not influence leaf thickness, leaf weight or chlorophyll content of P. heterophylla. Whether shaded or not, the relationship between Pn and PAR for each species could be expressed as y=alnx+b, and furthermore there was a significant (P.01) correlation between them. Pn and LCP values for all five lianas also significant (P.01) correlated. Shading reduced LCP values of P. heterophylla, C. grandiflora and E. fortunei but increased LSP of F. pumila.

结果表明，1薛荔对墙体附着力最强，它依靠大量的不定根吸固在墙体上，形成很好的覆盖效果，而且薜荔耐荫，遮光对其生长与覆盖的影响很小；爬墙虎的生长与覆盖速度最快，它主要依靠吸盘吸固墙壁，但在冬季或长时间遮光后出现明显落叶现象，影响其覆盖景观；其他3种都依靠不定根沿墙面攀援，附着力相对较差，但扶芳藤由于生长较快，叶色终年保持翠绿，也能形成相对较好的覆盖效果；2遮光4个月后，薛荔、凌霄和蔓九节的叶片变薄，相应地这3种植物单位面积的叶片重量都显著减轻；遮光还使凌霄和扶芳藤的叶绿素含量减少，使薛荔和蔓九节的增加，但对爬墙虎的叶片厚度、叶重和叶绿素含量都不产生明显影响；3无论遮光与否，5种植物的Pn与PAR之间的关系都可用y=alnx+b表示，并且都达极显著相关，Pn与光补偿点之间亦呈极显著相关；遮光还使爬墙虎、凌霄和扶芳藤的LCP下降，并使薛荔的光饱和点升高。
