转DREBIA基因多年生黑麦草Tl代萌发期耐盐性研究
A study on salt tolerance of T1 generation transgenic perennial ryegrass with DREB1A gene at germination period
摘要
Abstract
The seeds of transgenic perennial ryegrass （Loliurn perenne） with DREBIA gene were treated with various concentrations of NaC1 （0, 0.3%, 0.6%, 0.9%, 1.2%and 1.5%） to study physiological re sponses of transgenic plants under salt stresses. The results showed that the seed relative germination potential, relative germination rate, seedling height, leaf chlorophyll content, leaf water content and relative water content （RWC） decreased when NaC1 concentration increased. There were significant differences be tween the transgenic group and control group. Variation of root length was not obvious. The leaf relative conductivity had a positive relationship with the increase of salt concentration and with significant differ ences between transgenic plants and control plants. The salt tolerance of transgenic plants improved com- pared to nontransgenic plants. Transgenic T1 generation seeds of perennial ryegrass with DREB1A gene can be used as seed resources for salt soil improvement.关键词
