AM真菌生长发育影响因素及其对植物作用的研究

The growth influence factor of AM and the function of it for the plants

由真菌与植物根系共生形成的AM菌根在自然界中分布广泛,其生长发育受温度、土壤湿度等条件的影响;AM菌根可以促进宿主植物的生长已经在许多植物上得到证实,此外,此类菌根对提高植物的耐盐性、抗旱性及抗重金属毒性方面都有显著的作用。

AM mycorrhiza that are symbiotic combination of fungi and plant roots have distribution in the nature extensively, and the growth of them are subjected to the conditional influences, such as temperature and soil moisture, etc. The mycorrhiza of AM can promote vegetative growth of host plants. It has already got the confirmation on many plants, in addition, the mycorrhiza have obvious functions of raising saline tolerance, aridity tolerance and heavy metal poison resistance of plants.
