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 for the monitor of water pollution, Lemna minor, Spirodela polyrrhiza shleid and Azalla imbricate Nakai could be used as the monitors for the naphthalene pollution in water body because of their sensitivity to it.

在净化过程中，萘对5种水生植物产生生理毒害作用，且随萘浓度的增加显示出明显的毒害效应，表现为呼吸强度受到抑制，叶绿素含量降低；对POD而言，凤眼莲、喜旱莲子草随萘浓度增加逐渐升高，而浮萍、紫萍则表现出先升高然后降低，满江红一直降低。

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.

索夫农 、森那库斯和苏格拉底式的对话采用的模仿没有一个公共的名称；三音步诗、挽歌体或其他类型的诗的模仿也没有——人们把&诗人&这一名词和格律名称结合到一起，称之为挽歌体诗人或者史诗诗人，他们被称为诗人，似乎只是因为遵守格律写作，而非他们作品的模仿本质。

The relationship between communicative competence and grammar teaching should be that of the ends and the means.
