研究高等植物根系与真菌之間的共生营养問題有着巨大的理論和实践意义。真菌与高等植物的根系共生而形成菌根后,不但影响高等植物的无机营养过程,尤其是对氮肥的吸收有較大的作用。如菌根可促进植物利用某些难以吸收的含氮有机物,且可使之轉变为易被高等植物利用的化合物;此外,真菌在其生活期間,还可分泌出維生素乙、酶、生长素等物质以刺激植物的生长。据近年来苏联学者的研究指出,菌根还可影响到高等植物的某些生理作用,如可增加植物体内叶緑素的含量,增强植物体的蒸腾作用,同时真菌亦参与植物体内磷的吸收和轉輸过程。国外,对高等植物的菌根营养問題已有一定的研究,尤其是苏联,曾先后在1953年及1955年召开了植物菌根营养会議。会上着重报导和
It is of great theoretical and practical significance to study the symbiotic nutrition between root and fungi in higher plants. After the mycorrhizal fungi and the roots of higher plants form mycorrhizae, they not only affect the inorganic nutrition of higher plants, but also have a greater effect on the absorption of nitrogen fertilizer. Such as mycorrhizal can promote the use of plants to absorb some of the nitrogen is difficult to absorb organic compounds, and make it easy to be used by higher plants compounds; In addition, fungi in their lives, but also secrete vitamin B, enzymes, auxin And other substances to stimulate the growth of plants. According to the research of Soviet scholars in recent years, mycorrhizae can also affect some physiological functions of higher plants, such as increasing chlorophyll content in plants and enhancing transpiration of plants, while fungi also participate in the absorption of phosphorus in plants And transfer process. Abroad, the mycorrhizal nutrition of higher plants have been studied, especially the Soviet Union, has held in 1953 and 1955 plant mycorrhizal nutrition conference. At the meeting focused on reporting and
