Abstract: To ascertain whether transgenic engineering will affect resistance of seeds and seedlings to stresses, and consequently provide first-hand scientific information for environmental safety assessment of transgenic soybean, comparative studies were conducted in laboratory and greenhouse on transgenic soybean ARG, it′s counterpart n-ARG and Su 3 a traditional soybean cultivar in China. Results show at the germination stage, ARG was much weaker than n-ARG and Su 3 in resistance to high temperature and water stress, and similar to n-ARG but weaker than Su 3 in resistance to salt stress. At the seedling stage, given temperature stress (high-40 ℃, low-15 ℃) and water stress (flood and drought), ARG showed no advantage in height and biomass, and on the contrary, some disadvantages in certain conditions. For example, under a slight drought (relative water content 55%), ARG was obviously less than n-ARG in dry weight of the overground part, and also weaker than n-ARG and Su 3 in salt tolerance. The research shows the herbicide-tolerant transgenic soybean ARG is rather weak in competitiveness and invasiveness under stress conditions.
