Chilling stress induced photoinhibition of PSII and PSI, and active oxygen species might be one of the factors causing the decrease of the oxidizable P700. PSI seemed to be more sensitive to chilling in the low light than P5II.

低温弱光胁迫引起了PSII和PSI的光抑制，而活性氧的积累可能是氧化态P700下降的一个原因，而且PSI对低温弱光比PSII表现得更敏感。

Seven grapevine cultivars originated from different regions, i. e.'Carbernet Sauvignon' and'Queen of Vineyard'(two members of the Western Europe Cultivars Group),'Rizamat'(a member of the East Cultivars Group),'Red Double Taste'(a hybridized cultivar from Vitis vinifera L. and V. labrusca L.),'1103Paulsen','Red Globe'and 'Autumn Royal'(two new hybridized cultivars between cultivars groups which were warmly planted in recent years) were selected. After different drought stress, a combined measurement of gas exchange and chlorophyll fluorescence was conducted to evaluate the effects of drought stress to photoinhibition, as well as the role of photorespiration and xanthophyll cycle in photoprotective mechanism. After photorespiration and xanthophyll cycle were separately inhibited, the complementary effect of these two photoprotective pathways was discussed. Detached leaves of different grapevine cultivars, i. e.'Cabernet Sauvignon','Cabernet Franc','Merlot', and a rootstock,'1103Paulsen'were selected as materials, and photoinhibition degree, photorespiration activity as well as its photoprotective function under drought stress were studied. The results are as follows: 1. Under the same drought stress treatment, different photoinhibition degrees formed in different grapevine cultivars.

本研究选择不同起源地的葡萄品种－－包括西欧品种群的赤霞珠和葡萄园皇后、东方品种群的里扎马特、欧美杂种红双味、美洲种砧木1103Paulsen，以及近年来发展较快的品种群间杂交新品种红地球和皇家秋天等七个品种盆栽苗，在进行不同程度的干旱胁迫处理后，利用气体交换参数和叶绿素荧光参数同步测定的方法，研究干旱对其光抑制程度的影响，以及光呼吸和叶黄素循环组分在其光保护中的作用；并在分别抑制光呼吸和叶黄素循环的基础上，探讨了赤霞珠葡萄两种光保护机制的互补效应；同时选择不同的酿酒葡萄品种赤霞珠、品丽珠、梅鹿辄和砧木1103Paulsen的叶片，研究其离体干旱条件下光抑制程度、光呼吸活性及其光保护作用，结果发现： 1。

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。

孟庆伟等（1996）认为光呼吸可减轻光抑制，尤其在发生光合午休时更明显，而对光合作用却有反作用，Zelitch (1992)的研究表明光呼吸随温度的升高而升高，因此高蛋白小麦中午较强的光呼吸作用可能是其Fv/Fm下降较少，而净光合速率下降幅度较大的一个重要原因。
