查询词典 photoinhibition

Shanyou63 was more violable to midday photoinhibition than the two superhigh-yield rice hybrids.

在对自然条件下光抑制的研究中，发现汕优63比超高产杂交稻两优培九和华安3号更容易受到午间光抑制的伤害。

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。

Drought caused photoinhibition and increased the damage of reactive oxygen. Antioxygenation of fast-growing 107 was stronger than Populus pseudo-simonii.2. As expected, both NO and ABA can induce stomatal closure of detached populus leaves.

107杨具有较强的抗氧化能力，干旱诱导酶活性提高；小青杨抗氧化能力较弱，造成活性氧积累，导致光氧化伤害。

Hystrix canopy declined slightly at the midday, suggesting the occurrence of reversible photoinhibition. Owing to the lower maximum net photosynthetic rate in sun leaves and the ability to effectively and consistently utilize the scattered light and/or transmitted light, C. hystrix saplings could survive low light intensity, grow well at the edge of the forest and in the understorey, and eventually become one of the dominant species in upper layer of the community.

刺栲冠层阳生叶的最大光合能力比较低，整个冠层叶能高效而稳定地利用散射和透射光，这些特征使得常绿的刺栲幼树能在林边或林下良好生长，较好地适应不同的光环境并成功渡过幼苗期，最终成为群落中的上层优势种。

As to'Cabemet Sauvignon'and'Queen of Vineyard', which belong to the'West Europe Cultivars Group', no obvious decline of Fv/Fm was found in their potted plants even under severe drought stress. Their photosynthetic abilities also greatly recovered after rewatering, i. e. no serious photodamage was formed in these cultivars under drought stress. Between them, the φPSⅡ of 'Queen of Vineyard'under severe drought stress was much lower than that of'Cabernet Sauvignon', which suggested that the light use efficiency of the former was much lower than the latter under severe drought stress. The potted plants of'Autumn Royal'and'Rizamat' sustained high Fv/Fm and φPSⅡ before moderate drought stress, but seriously declined under severe drought stress, which indicated that these cultivars had a weak resistant ability to extreme drought stress. A hybridized cultivar of Vitis vinifera L. and V. labrusca L.,'Red Double Taste', its Fv/Fm and φPSⅡ expressed mild decline along drought stress grade.φPSⅡ of'Red Double Taste'was the highest among seven cultivars under severe drought stress condition, which might closely connected with its high photorespiration activity. Another new cultivar,'Red Globe', and a rootstock,'1103Paulsen', the Fv/Fm and φPSⅡ of their potted plants declined markedly under slight drought stress, which suggested that they held a weak ability to defend against photoinhibition.

西欧品种群的赤霞珠和葡萄园皇后，其盆栽苗的Fv／Fm直到重度干旱胁迫下仍没有明显的降低，且复水后光合能力恢复程度较高，即干旱没有给这两个品种造成严重的光破坏，而两个品种之间，葡萄园皇后在重度干旱胁迫下的φPSⅡ明显低于赤霞珠，说明其光合器官在严重干旱胁迫时对光能的利用率较差；新品种皇家秋天和东方品种群的里扎马特在中度干旱胁迫下仍可维持较高的Fv／Fm和φPSⅡ，但在重度干旱胁迫下则降低幅度较大，说明其抵御极端干旱胁迫的能力较差；欧美杂种红双味的Fv／Fm和φPSⅡ随着干旱胁迫程度的增加呈现平缓的下降趋势，而且其φPSⅡ在重度干旱胁迫下是七个品种中最高的，这应该与其此时仍维持较强的光呼吸活性有关；红地球和砧木1103Paulsen的Fv／Fm和φPSⅡ在轻度干旱胁迫下就明显下降，表明干旱条件下其抵御光抑制的能力较差。

Sophora japonica and Ligustrum lucidum appeared photoinhibition at noon when they fall across severe water stress.

国槐和女贞遇到严重水分胁迫时中午均出现光抑制现象。

There are two classes of photoinhibition, chronic and dynamic.

有两种不同的光抑制：动态的和静态的光抑制。

Great progress in the the mechanism of photoinhibition has been made in recent years.

光抑制是目前高等植物光合作用研究中的热点，近些年来无论是对其本质的认识，还是机理研究都已取得很大进展。

Plant to light, temperature, CO 2 and the characteristics of chlorophyll fluorescence under photoinhibition conditions were studied.

及原种为材料，研究了光合作用对光照、温度、CO2 的响应和光抑制条件下的叶绿素荧光特性，结果如下：1。

In the past many studies the two classes of photoinhibition are separated each other.

动态光抑制是能量耗散机制加强运转的结果，往往发生在阳生植物上。

Do you know, i need you to come back
