类胡萝卜素

Excessive Cd greatly increased the Cd content, and reduced the contents of chlorophyll, carotinoid, Mg, Fe and K in the leaves, particularly under HL treatment.

镉胁迫显著增加了紫茉莉叶片的镉含量，减小叶片叶绿素、类胡萝卜素、Mg、Fe和K的含量，对HL植株影响最大。

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。

Of ch a, and value of cha b/ carotinoid and cha b/flower pigment are both reduced in ChangLi 15 and Purple leaf plum, the color of the leaf is moreobvious; Under shade environment, ch a/b is reduced.

叶绿素对干旱胁迫的敏感性大于类胡萝卜素，干早胁迫对叶绿素b的伤害大于叶绿素a，到重度胁迫时，两个品种叶绿素b含量分别比对照降低了32.9％和37.7％。

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。

Swiss chard: A leafy green vegetable packed with carotenoids that protect aging eyes.

瑞士甜菜：多叶的绿色蔬菜，富含防止眼睛老化的类胡萝卜素。

The effects of different concentrations of terramycin and chloromycetin on biomass, size, and contents of chlorophyll and carotenoid in alga Platymonas subcordiformis were studied under room temperature.

在室温下。研究了不同浓度的土霉素和氯霉素对亚心形扁藻细胞的数量、大小以及叶绿素、类胡萝卜素含量等方面的影响。

The alga had low biomass and more carotenoid with increase in chloromycetin concentrations.

浓度越大，扁藻细胞数量增幅越小，类胡萝卜素越多。

The content of chromoplast pigments and the neutrality volatile aroma of flue-cured tobacco of Yunnan Dali and Zimbabwe was clearly more than other producing area. The content of carotenoid and its degrading products in the Yunnan flue-cured tobacco was clearly more than that of the others.

其中云南大理和津巴布韦烤烟中质体色素及其降解形成的中性香气物质含量明显高于其他产区，云南烤烟中类胡萝卜素和其降解形成的香气物含量明显高于其他烤烟。

The commercial interest for carotenoids can be explained mainly by their use as colorant, nutraceutical, or antioxidant in food and cosmetics.

商业利益为类胡萝卜素可以解释，主要是利用他们作为着色剂， Nutraceutical公司，或抗氧化剂，在食品和化妆品。

And recovery 30 days after topping could make sure there are enough carotenoids and soluble sugar in tobacco leaf cells. Besides the contents organic acid, protein, nicotine and potassium element are controlled in a certain scope, then tobacco leaves after curing kinds of compound proportion coordination bear more fragrance precursor.

打顶后30d采收烟叶，叶片细胞内既含有较多类胡萝卜素和可溶性糖，又能将有机酸、蛋白质、烟碱和钾含量控制在一定范围内，使烟叶调制后各种化合物的比例协调。
