Whith the increase of water supply,the biomass,tree height,total branch number and length,total leaf number and area,specific leaf area and fine root length increased,and root/shoot biomass,sclerophyllous characters and leaf succulence degree decreased.

随着施水量的增加，幼苗生物量、株高、总枝数和长度、总叶片数、总叶面积、比叶面积和细根长逐渐增大，而生物量根冠比、硬叶特征和叶肉质化程度逐渐减小。

These results suggest that leaf Na(superscript -) and Cl(superscript -) accunulations are the main factors affecting leaf succulence and leaf Na(superscript +) plays a critical role.

内地重盐碱地土壤表层和空气温度高，尤其土壤含水量低是内地盐地碱蓬叶片肉质化程度高于海边生境条件下的重要原因。

The main indictor examined were anatomical structrue ofleaves,movement and shedding of leaves,leaf water potential andwater saturation deficit,leaf succulence and specfic leaf area,rate of water loss,slope of water release curve.water parametersof PV curveψo、Vs、Va、Emax and TW/DW et al.

The white square represents Canadian vast national territory, the Canadian very big area national territory whole year the snow time above 100 days, therefore expressed with the white; Two red vertical stroke rectangles represent the Pacific Ocean and Atlantic separately, because west Canada is close to the Pacific Ocean, east near Atlantic; The red maple leaf represents all Canada people, Canada is known as "country of the maple leaf" the fine reputation, the Chinese sweet gum is this country's country tree, the maple leaf is the Canadian nationality's symbol.

白色正方形代表加拿大辽阔的国土，加拿大很大面积的国土全年积雪期在100天以上，故用白色表示；两个红色竖长方形分别代表太平洋和大西洋，因加拿大西濒太平洋、东临大西洋；红枫叶代表全体加拿大人民，加拿大素有"枫叶之国"的美誉，枫树是该国的国树，枫叶是加拿大民族的象征。

Planting density, yield components, agronomic traits, leaf area index and group leaf area duration were analyzed in the study, the results showed that Xundan 20 had long trimness in high density. The high value of leaf areas kept over 60 days, and the effective illumination hours（PAR_Avg≥300mmol/s/m2）were over 780 hours in the whole developing stage.

结果表明：浚单20在高密度条件下维持了较高的整齐度，叶面积高值持续期达60d以上，整个玉米生育期内PAR_Avg≥300mmol/s/m2的有效光照时数达780h以上。

The feeding habits of the larva is more extensive, also eat to fresh leaf of the elm , mulberry leaf , the leaf of the general term for paulownia, phoenix tree and tung tree , blade of the legume besides the above food, and various kinds of corpse and jujube kernel of insect process piece produced to sift; When the food is scarce , can even bite food wooden raising case and paper , various kinds of grass one , blade ,etc.

幼虫的食性更为广泛，除以上食物外还吃鲜榆叶、桑叶、桐叶、豆科植物的叶片，以及各种昆虫的尸体和枣仁加工筛出的碎屑；当食物缺乏时，甚至还可咬食木质的饲养箱和纸片与各种草棵、叶片等。

It\'s possibly that increase of hydraulic limitation with tree height influenced leaf water potential and turgor as well as leaf structure,which strengthened hydraulic limitation on leaf gas exchange characteristics including photosynthesis and transpiration rate, resultantly influenced carbon assimilation and CO_2 fractionation and increased water use efficiency and drought resistance capability.

应该是水力限制影响了叶片的水势和膨压、同时造成叶片的结构发生改变，而结构的改变加剧了水力对气体交换的限制、影响了光合碳同化以及对CO_2的分馏效应、使叶片的水分利用效率和抗旱性增强。

The biological characters of p5CS-bar gene transgenic wheatgrasse and control plants were observed and analysed that none but caudex have marked differences(0.05); The values of plant height、spike length、spike width and stem/leaf are less than control plants, leaf length and leaf width are more than control plants; Under the same condition of growth and climate to compare transgenic wheatgrass with control plants we can see that trning-green sage is advance, defer procreate period, long viridity period, growth speed become slow and the figure of curves is"S", more tillers.
