易脆毛霉多糖对烟草幼苗的促生效果及烟草花叶病毒的抑制作用
Growth Promotion on Tobacco Seedlings and Inhibition on Tobacco mosaic virus of Polysaccharide from Mucor fuagilis
摘要
Abstract
To understand the effects of polysaccharide from Mucorfuagilis (PMF) on disease resistance and growth promotion,its effect on tomato seedling growth and inhibition to Tobacco mosaic virus (TMV) were analyzed by pot experiment and half leaf method.The results showed that the polysaccharide treatment had obvious growth promotion on tobacco seedlings,the maximum leaf area,aboveground fresh weight,root fresh weight,chlorophyll content and net photosynthetic rate of tobacco seedlings obviously improved.The preventive effect of polysaccharide treatment on tobacco was the best as 62％.The passivation effect was the second.The therapeutic effect was the worst below 40％.So the PMF not only could promote the growth of tobacco seedlings,but also had better preventive effect on TMV,which could provide a reference to develop and utilize the polysaccharide.关键词
