不同微生物多糖对植物生长和植保素累积的影响
The Effects of Different Kinds of Microbial Polysaccharides on Plant Growth and Phytoalexin Accumulation
摘要
Abstract
This study selects from different kinds of bacteria,yeasts and fungi,what extracts Polysaccharide on fermentations and mycelium from them.Comparison effects of different kinds of microbal polysaccharides on the corn growth and soybean phytoalexin accumulation.The experimental results showed that:the polysaccha-ride treatment of fungal fermentation increased 3 1 .75% compared with the control in root length,the germina-tion rate increased by 58.33%,and the weight gain was higher than the control treatment 55.54%.In the de-termination of induced phytoalexin synthesis,the inducing effect of fungi polysaccharides is the best,and its OD value reached 0.685,which is 3.98 times higher than that of the control at a wavelength of286 nm in fifth days in soybean leaves.On concentration screening experiments,in the 6 th day,when inducing concentration of fungi polysaccharides reached 50 mg/ml,the soybean phytoalexin accumulation reached maximum,the OD value is 0.744,that is 1 1 .27 times higher than that of the control group.关键词
