We have carried on comparing research on the changes of photosynthetic physiological characteristics , water metabolism , membrane protective system , material metabolism , cold resistance and the content of endogenous hormone of t . media cv . hicksii grown at different light intensity conditions 分别对不同光照条件下的曼地亚红豆杉的光合生理特性、水分代谢、膜保护系统、物质代谢、抗寒性及内源激素的变化进行了比较研究。
The cold resistance and the water permeability resistance of the recycled coarse aggregate concrete were also test . the principle and the influencing factors of the drying shrinkage , the freeze thaw action and the water permeation action of the recycled coarse aggregate concrete were briefly narrated 还测试了再生粗骨料混凝土的抗冻性和抗渗性,简要叙述了再生粗骨料混凝土干缩变形、冻融作用、渗透作用的机理以及影响因素。
Consequently the seedlings enhance the leaf cold resistance through improving fpro , spro , ssug contents and declining sta content with temperature falling , which can reduce the organisation osmosis power and improve the capacity of water - keeping . the taxol , the import 自然光照条件下的植株aba含量大幅度提高、 zrs含量降低导致抗寒性增加;一层遮荫处理下的植株主要以降低ga含量来提高抗寒力; h层遮荫抗寒力的提高主要与iaa含量的降低密切相关。
Driven by the cauliflower mosaic virus ( camv ) 35s promoter , the er - shsp over - expressed constitutively . the growth and the phenotype of transgenic plants can be used for researching the function of er - shsp in improving tomato ' s cold resistance and the er - shsp chaperones function in vivo . after degested by kpnl and xbal enzymes from the pbs - er plasmid , the gene er - shsp - lehsp21 . 3 was inserted into the prokii vector to construct an eukaryotic expressing vector 利用基因工程方法,将内质网小分子热激蛋白基因( endoplasmicreticulum - locatedsmallheatshockproteingene , er - shspgene ) - lehsp21 . 3导入到番茄体内,使之在植物体中组成性表达( constitutiveexpression )内质网小分子热激蛋白( er - shsp ) ,观察转基因番茄在低温条件下的生长和表型反映,研究er - shsp在提高植物耐寒性中的作用,同时为体内研究er - shsp的分子伴侣机制提供依据。
Expressions of a series of its cor ( cold - regulated ) genes are promoted transcriptionally by transferring cbf ( c - repeat banding factors ) gene into plants then 1 ~ 2 of outside efficient cor genes are transformed , which is an essential direction of genetically improving of cold resistance in plants and an important approach in enhancing cold resistance of plants effectively 利用导入冷应答转录因子基因( cbf )来从转录水平上促进植物自身的大量冷诱导基因表达,并结合导入1 2个高效抗寒基因的策略,是当前植物抗寒遗传改良的基本方向,可能成为有效改善植物抗寒性的重要途径。
In our country , water crisis is increasingly serious and the pollution eara of soil heavy metal cadmium expands continuously . under this situation , my dissertation studys alfalfa which has good economic value and strong drought and cold resistance . in the study , resistance experiments of heavy metal - cadmium arid znic are carried out 本论文是在我国水资源危机日趋严重,土壤重金属镉污染面积不断扩大的情况下,针对抗旱、抗寒能力强,生物量大、经济实用价值高的紫花苜蓿,进行的重金属镉、锌的抗性试验研究。
The first step was that the activity descended , and in the first 10min the activity was lower than that of the control , and then kept rising . sod and asp activities increased in a wide range , while pod activity increased in a narrow range . all of these have shown that sod and asp may play a main role during the cold resistance process , while pod acted as an assistant factor 低温处理对脯氨酸含量影响很大,低温处理3min时脯氨酸含量达到对照的3 . 60倍, 5min达到对照的23 . 04倍之多, 10min时又有较大幅度下降,但仍达到对照西南农业大学硕士学位论文摘要旦里里里里里绝里里皿理里里里里里的14 . 79倍,然后开始下降,在处理30min时又有一定上升。
