Eco-toxicology effects of compound stress of Cu, Cd, Pb, Zn and As on growth, chlorophyll content and protective enzyme of Juncus Effuses were studied using pot culture. Concentrations of the heavy metals in the soil were designed according to the State Soil Environmental Quality Standard. Considering practical application, soils contaminated with tailings and wastewater from Lead/Zinc mining were also used in the experiment.

In this assessment, two groups of evaluation factors were used: one group is stipulated in "Environment quality standards for surface water (GB3838-2002)"; the other factors included main pollutants of Jinhe River, such as kjeldahl nitrogen, nitrite nitrogen, nitrate nitrogen and chlorophyll a, and the standards of some of them were given by the author on the basis of relative data.

在此评价中，采用了两组评价因子，一组是地表水环境质量标准(GB3838-2002)内的因子，一组除了标准内的水质因子，还包括了津河的主要污染物凯氏氮、亚硝酸盐氮、硝酸盐氮和叶绿素，这些污染物的标准是经过查阅资料自定的。

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。

We studied the effects of different concentrations of seawater (diluted in 1/2 Hoagland's solution) on the biomass and chlorophyll, ion, soluble sugar and soluble protein contents of Lactuca indica seedlings by sand culture in the greenhouse.

采用温室砂培方式，研究了不同稀释配比的海水处理8天对苦荬菜幼苗生物量、根冠比、叶绿素含量、离子含量、可溶性蛋白和可溶性糖含量的影响。

Along with seawater stress strength upward, the ratio of root to shoot, Na+, Cl- and soluble sugar contents were increased significantly. Under the 10% and 20% seawater treatments, chlorophyll contents have no obvious difference compared with the control, but significantly decreased when the seawater stress further increased. Under the 10% seawater treatments, K+ contents in the shoot and root of Lactuca indica seedlings have no distinct difference compared with the control, but along with seawater stress strength upward, K+ content were markedly decreased by degrees. However, soluble protein content first increased then decreased with seawater concentration augment.
