查询词典 chlorophyll

The results showed: 1 Alfalfas grown for different lengths of time had considerable influence on photosynthetic characteristics of which the most important was stomatal conductance followed by transpiration rate and the chlorophyll relative content. 2 Diurnal variation in Pn and Tr had two peaks, and an obvious midday depression. 3 The net photosynthetic rate was significantly positively correlated with photosynthetic radiation, stomatal conductance, the relative chlorophyll content, and transpiration rate. The net photosynthetic rate was significantly negatively correlated with intercellular CO2 concentration.

Quenching of chlorophyll fluorescence decreased and Non-photochemical Quenching of chlorophyll fluorescence increased for both alfalfas under drought stress. Generally speaking, qP decreased less and qN increased more in the high drought-resistance alfalfa than in the low drought-resistance alfalfa, suggesting that when under drought stress, the electron transport activity and photosynthetic apparatus was damaged less in the alfalfa with high drought-resistance than in the alfalfa with low drought- resistance.

PSⅡ光化学淬灭系数、非光化学淬灭系数的变化表现为干旱胁迫下两种紫花苜蓿qP值降低、qN值升高，总体上抗旱性强的紫花苜蓿qP降低的幅度低且qN升高幅度大，表明抗旱性强的紫花苜蓿PSⅡ反应中心电子传递活性受到的影响小，光合机构的损伤程度低。

利用SPAD-502叶绿素检测仪和常规方法对贵州兰花7个种的21个品种叶绿素含量进行了比较分析。

With the prolongation of the time of Pb and Cd stress, the chlorophyll content of the clones and families were induced to first increase and later decrease, except that NEF14 and NEF12 were downtrend at all times. With the increasing of Pb and Cd concentration the chlorophyll content decreased fastly in the latter stress period. The downtrends of NE60 and NEF14 which were stress-resistence were small.

随胁迫时间的延长，杂交鹅掌楸无性系和家系(但NEF14和NEF12一直呈下降趋势)的叶绿素含量先升后降，随着Pb、Cd处理浓度增大，在胁迫后期叶绿素含量下降越明显，抗性较强的NE60无性系、NEF14家系降幅较小。

Simulated water stress experiment on the five-leaf stage of maize growth with different concentrations of polyethylene glycol in nutrient solution was performed to study the effects of water stress and rewatering on chlorophyll content,chlorophyll fluorescence kinetic parameters,photosynthetic parameters and soluble sugar content.

At the late stage of stress (10 d), the chlorophyll degradation of own-root was accelerated, salt ion destroyed chlorophyll photosynthetic structure, the Pn, Tr and Gs of own-root plant were still significantly decreased, Ci was significantly increased, while Ls was significantly decreased, WUE was significantly decreased because the decreasing extent of Pn was more obvious than Tr, leading to a poor water use.

自根苗和嫁接苗叶片和根系中脯氨酸、可溶性糖、可溶性蛋白质含量在胁迫初期均会被诱导上升，随着胁迫时间的延长，有的持续上升，有的显著下降，但嫁接苗与自根苗相比，不论叶片还是根系中，各指标均显著高于自根苗，渗透调节能力相对较强。

The chlorophyll, ch a and ch b content of Purple leaf plum is reduced, flower pigmentcontent is increased, flower pigment and chlorophyll value is increased under water stress, madethe color of the leaf is more obviously.

遮荫环境下，紫叶李叶片总叶绿素、叶绿素a、叶绿素b含量上升，花色素含量和花色素与叶绿素含量的比值下降，叶片出现复绿现象，不利于叶片显色。

Low chlorophyll b rice mutant and the wild type rice (Zhenhui 249) were used to study the effects of low chlorophyll b on themiostability of photosystem Ⅱ in mutant by measuring their changes in chlorophyⅡ fluorescence parameters and polyphasic chlorophyⅡ fluorescence transients under different temperature treatments.

The result indicates that with organic fertilizer and inorganic nitrogen fertilizer can obviously increase the leaf dimension coefficient, enhance the content of chlorophyll and soluble protein, improve the SOD activity of flag leaf, depress the content of MDA, postpone the speed of decrepitude of flag leaf,; The status with high content of chlorophyll and leaf dimension coefficient lasts longer with organic fertilizer than with inorganic nitrogen fertilizer and the flag leaf have longer functioning time; the combination of inorganic nitrogen fertilizer and organic fertilizer can substantially postpone the speed of decrepitude of winter wheat.

在国内持续时间最长的肥料长期定位（28年）试验条件下，研究了肥料持续施用下冬小麦花后叶面积系数等生理指标的变化，结果表明施用有机肥、氮肥，可明显增大小麦的叶面积系数，增加叶绿素含量和可溶性蛋白含量，提高旗叶的SOD活性，降低丙二醛的含量，延缓旗叶的衰老；施用有机肥较施用氮肥，叶绿素含量及叶面积系数持续高值时间长，旗叶有更长的功能期；长期氮肥与有机肥配施能显著延缓小麦衰老。
