橡胶树AM菌根研究进展

橡胶是四大工业原料之一,在交通、军用工业中尤为重要。其中天然橡胶的主要来源是巴西橡胶树(H evea brasiliensis M uell.A rg.),它在我国南方热带地区广为栽培,是重要的经济树种和用材树种,因而是工业与民用的重要资源。已有研究证实:橡胶树根系可以形成AM菌根(arbuscular mycorrhiza)。AM菌根是广泛分布的一类内生菌根,能够促进宿主植物吸收土壤中的养分,增强宿主的抗逆性,有利于植物生长。近30a来,国外一些学者对橡胶树菌根真菌的资源与分布,菌根真菌对苗木营养和生长效应以及提高苗木抗逆性方面进行了研究。而国内尚未有此方面的研究报道。本文的报道旨在对我国橡胶树栽培菌根化研究方面能起到推动作用。

Advances in Researches of Arbuscular Mycorrhizae in Hevea brasiliensis

The presence of endomycorrhiza in rubber trees was found long ago. But compared with other plants, few research on arbuscular mycorrhizae in rubber tree was conducted at home and abroad. In this paper, the advances and main achievements in recent years were reviewed, which included the survey of endomycorrhiza in rubber trees, the mycorrhizal effects on growth and nutrition of rubber trees and enhancing disease resistance of the trees. The preliminary suggestion was proposed to enhance the research, application and the development of endomycorrhiza in rubber trees.
