食用菌多糖对植物病毒抑制作用的初步研究
0
()
摘要:
利用食用菌平菇(Pleurotus ostreatus)、金针菇(Flammulina velutipes)和香菇(Lentinus edodes)中提取的多糖,在寄主苋色藜上分别对烟草花叶病毒(TMV)和黄瓜花叶病毒(CMV)进行抑制作用试验.结果表明,在不同浓度多糖的寄主上,3种食用菌多糖对TMV和CMV都有明显的抑制作用.在不同浓度多糖的寄主之间的作用效果没有显著的差异性;在抑制和钝化作用方面,不同的食用菌多糖之间存在显著的差异性,而在治疗作用方面差异性不显著.其中平菇多糖对TMV和CMV的抑制作用显著优于金针菇和香菇多糖.

Preliminary Study on the Inhibition of Polysaccharide of Edible Fungi to Plant Virus
()
Abstract:
In this paper, the inhibition of polysaccharide of edible fungi (Plenrotus ostreatus,Flammulina velutipes,Lentinus edodes) to plant virus (TMV,CMV) on host Chenopodium anarenticcolor were studied.The results showed that the polysaccharide extracted from three kinds of edible fungi at different concentrations could inhibit TMV and CMV effectively.Statistical analysis showed that there were no significant differences between the control effect at different concentrations,furthermore,there obviously existed inhibition and passivation on virus,but no cure effects.The inhibition of polysaccharide extracted from Pleurotus ostreatus to TMV and CMV was superior to that of polysaccharide from Flammulina velutipes, Lentinus edodes.
Key words:  polysaccharide of edible fungi,plant virus,inhibition,passivation,cure
