Abstract
【Objective】 This study aimed to filter out the polysaccharide with good inhibition on cucumber mosaic virus(CMV).【Method】 In this paper,the half leaf method and pot experiment were respectively used to measure the inhibition effect of 10 polysaccharides on CMV and tobacco growth.The change of CMV concentration in tobacco and the field efficacy trials of C.verscicolor polysaccharide on CMV were measured by indirect ELISA and disease index,respectively.【Result】 Fungi polysaccharides of different concentrations all had certain inhibition on CMV.The inhibition effect was improved as the increase of concentration.In different treatments,the prevention effect was the best,followed by deactivating effect.The C.verscicolor polysaccharide of 1 000 mg/L had well preventing effect(79.83%) on CMV.It also promoted the growth of tobacco.Plant height,stem girth,fresh weight and leaf area were higher than CK by factors of 87.37%,48.28%,58.03% and 222.27%,respectively.After being treated by C.verscicolor polysaccharide,the CMV in the tobacco was decreased by 50.76%-89.96% compared to CK.The field efficacy trials indicated that the C.verscicolor polysaccharide had high control effect to CMV for a long time.The control effects at 7,14 and 21 d since spraying C.verscicolor polysaccharide were 74.30%,68.07% and 62.03%,respectively,which were better than ningnanmycin and virus A.【Conclusion】 The C.verscicolor polysaccharide has well control efficiency on CMV and good application value.
