类叶绿素

The results of absorption spectra of chloroplasts showed that NO alleviated the effects of Cd on absorption spectra of chloroplast by raising the relative absorbance at 436 nm,480 nm and 470 nm,which caused lower contents of carotinoid and chlorophyll.

结果发现，Cd对叶绿素a、叶绿素b和类胡萝卜素含量都有不同程度的降低，NO处理缓解了Cd的影响，使叶绿体室温吸收光谱的吸收率提高；Cd导致686 nm处峰偏移4 nm，峰值降低33%，734 nm处峰值降低23%，外源NO缓解了Cd对光合系统的影响，使得叶绿体低温荧光光谱在686和734 nm的峰值分别仅下降17%和10%；以DCPIP为人工电子受体， Cd处理的叶绿体中DCPIP还原速率较慢，光合电子传递(H2O→DCPIP)速率降低1.5倍，外源NO处理显著缓解了Cd对电子传递链的抑制，使其光合电子传递速率恢复到对照的水平。

The Ф_,Fv/Fm and qP were increased but qN was decreased with increasing of chlorophyll a,the rate of heat dissipation was increased with the increasing of chlorophyll b,and the carotinoid increasing enhanced the rate of heat dissipation of dryland and carbon assimilation of irrigated cultivar.

提高叶绿素a含量能显著提高叶片ФPSⅡ、Fv/Fm、qP和降低qN；叶绿素b含量的升高能显著增强热耗散，增加类胡萝卜素含量则促进水地品种叶片光能的光合碳同化作用和旱地品种的热耗散。

The concentration of pigments and other chemical components including anthocyanins,chlorophyll a,chlorophyll b,carotenoids,solubility sugar and 10 kinds of macroelement and microelement were investigated using P.virginiana Schubert',and calculated the relativity of the data.

本研究以紫叶稠李(Prunus virginiana'Schubert')为试材，对其不同叶位叶片进行花青苷、叶绿素a、叶绿素b、类胡萝卜素、可溶性糖及10种常量和微量元素的测定，并进行相关性分析。

For example red autumnal leaves is bright red broadleaf plant, red the flowers observing a part of a historical period such as back laurel, contain cyanine element inside their mesophyll cell, consequently the front of blade or the reverse side present red; The lamina that wait is in Gong Sang, nandina synthesis of the chlorophyll below weak light is much, kind of carotene falls in strong

例如红叶朱蕉。红背桂等观叶花卉，在它们的叶肉细胞内都含有花青素，因而叶片的正面或背面呈现红色；红桑。南天竹等的叶片在弱光下叶绿素合成多，在强光下类胡萝卜素合成多，故放在半阴处培养叶色发绿，放在强光下养护，则叶色发橙；金边吊兰。金边虎皮兰叶片的不同部位上细胞内分别含有叶绿素和叶黄素，所以叶片呈现出黄绿相间的两种颜色。

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。

The experimentation indicated that chlorophyll and carotenoids had no remarkable relationship with the chlorophyllase and LOX during the growth of flue-cured tobacco leaf.

本试验表明，烤烟发育过程中叶绿素、类胡萝卜素与叶绿素酶、脂氧合酶间无显著相关关系。

In addition,the leaves of the control plants appeared to be much reder than the transgenic tomato,and the change were obvious followed by far from the treated time at low temperature,which suggested that the constituently expression of the chloroplast sHSP had some protective fountions to the tomato at low temperature.2 Effect on contents of MDAMDA is the product that membrane lipid peroxide and the contents of MDA in plants can reflect the degree of the damage that the plants are encountered to some extent.

低温处理6周后，转基因苗叶片中chla，cib含量及叶绿素总量明显高于对照，反应叶绿体中类囊体垛叠程度的chla／the比值也大于对照，可见冷害条件下转基因植株体内叶绿素的破坏程度小。4））t％hs用：低温Al：Pll6周，测定植物光合作用的重要指标净光合速率、蒸腾速率、气孔导度、胞间隙CQZ鹏，结果显示赂因番茄的即雏率、蒸腾速率、气孔导度均明显高于对照，而胞间隙COZ 氏于对照。

By the chemical composition of carotenoids can be divided into categories, anthraquinone, naphthoquinone type, type of flavonoid, curcumin category, indigo type, chlorophyll a total of seven kinds of categories.

按化学组成可分为胡萝卜素类、蒽醌类、萘醌类、类黄酮类、姜黄素类、靛蓝类、叶绿素类共7种。

Mol-1 of ozone are compared to those from the control run, indicating that from the heading to mature stage contents of chlorophylls a and b as well as the total increase first and then drop, but the carotenoid content and the value of value of chl a/b keep steadily rising and declinling, respectively, there is no significant decrease in the net photosynthetic rate and stomatic conductance during the early stage of heading but their drops increase gradually with prolonged smoking time.

mol-1的O3处理下，与对照相比，从抽穗期到成熟期冬小麦叶绿素a、叶绿素b和总叶绿素含量均呈先上升后降低的变化趋势，而类胡萝卜素的含量和Chla/b的比值则分别持续升高和下降，净光合速率和气孔导度在抽穗初期无明显下降，但是随着熏蒸时间的增加下降幅逐步变大。

The results shoed that after spraying 1 and 5 mgL^(-1) of anthraquinones, the photosynthetic rate raised by 38.03% and 39.73%, chlorophyll content increased by 3.53% and 3.83%, and MDA content decreased by 11% and 23%, respectively. The anthraquinones could absorb solar UV radiation, and convert the harmful UV into blue or yellow light which can promote plant photosynthesis. It as suggested that foliar-spraying appropriate concentrations of aloe's anthraquinones could promote wheat photosynthetic activity, alleviate UV harm, and thus, increase wheat yield.

结果表明：在灌浆期用浓度为1和5mgL^(-1)的芦荟蒽醌类物质喷施小麦，光合作用速率分别提高了38.03%和39.73%；叶绿素含量分别提高了3.53%和3.83%，丙二醛含量分别降低了11%和23%；蒽醌类物质能够吸收太阳中的紫外线，并将紫外线转换成能促进光合作用的蓝光或黄光；芦荟蒽醌类物质能促进小麦光合作用效率，减轻紫外线对小麦的损伤；喷施合适浓度的芦荟蒽醌类物质能够提高小麦产量。
