利用光谱反射指标得出的叶绿素含量、叶黄素循环库的大小与黄瓜的盐害程度及不同品种的耐盐程度有密切关系，反射光谱特性可以用来作为筛选黄瓜耐盐的生理指标。

Xanthophyll oleoresin is obtained from fermented marigold flowers by extracting and refining. Its main components are carotenoids like xanthophylls and oils and wax existed in plants.

叶黄素树脂是由万寿菊鲜花经发酵、提取、精制而成，其主要成份是以叶黄素为主的各种类胡萝卜素和植物中原有的油脂和蜡。

The results showed that the rate of photosynthesis, the contents of individual and total carotenoids and the pool size of xanthophyll cycle decreased with age increasing of the leaf.

结果表明：随着叶片的衰老，光合速率、类胡萝卜素不同组分及总的类胡萝卜素含量和叶黄素循环库下降；不同叶龄的叶片经高光胁迫后，第 5叶qN增加的幅度比第 6叶和老叶(第 3和 4叶)大；与高光胁迫前相比，第 3、4、5和 6叶光系统Ⅱ激发压(1-qP)分别增加了 4 4 %、5 7%、19%和 4 5 %；第 5叶具有高胡萝卜素含量和高紫黄质到玉米黄质的转化，这与其呈现较强的抗高光胁迫相一致。

2000B.The xanthophyll cycle plays a role in protection of PS II from photoinhibition in senescent leaves by dissipating excess excitation energy, in particular when the leaves are exposed to high light levels (Lu et al.2001a, b).

。叶黄素循环中发挥作用，在保护的PS二，从光合作用的衰老叶片逐渐消退过剩的激发能量，尤其是当叶片暴露于高光层次（卢等al.2001a ， b ）款。

Do plants photosynthesize when chlorophyll transforms to xanthophyll?

叶绿素转变为叶黄素后是不是就不会行光合作用了？

结果表明，Fm、Fv/Fm、PS Ⅱ无活性反应中心数量和Q_A的还原速率在强光下降低，在暗恢复时升高；而PS Ⅱ反应中心非还原性Q_B的比例在强光下增加，在暗恢复时降低。

It has been suggested that the decline of thermal dissipation through xanthophyll cycle is mainly due to decrease in electron transport rate by SM treatment in maize leaves.

All the results above suggested that it was the cyclic electron transport but the xanthophyll cycle that play the key role in the photoprotection of the rice hybrids. The cyclic electron transport was enhanced under excessive light, thus more ATPs, which could be used for the repair of the damaged D1 protein, would be produced by cyclic phosphorylation.

这些实验结果首次阐明，叶黄素循环的热耗散在杂交稻的光保护中不起关键作用，而环式电子传递则对于杂交稻的光保护起至关重要的作用，其机理可能在于强光条件下环式磷酸化的加剧生成大量ATP用于光破坏的修复作用，同时避免类囊体膜的过度酸化，从而导致强光下qN的下降。

The concept of equivalent rotationally rigidity is offered and the formula of rotationally rigidity is obtained.
