丛枝菌根真菌对旱稻生长、Cd吸收累积和土壤酶活性的影响
Effects of Arbuscular Mycorrhizal Fungi(AMF)on Growth and Cd accumulation of Upland Rice and Soil Enzyme Activities in Cadmium Contaminated Soil
摘要
Abstract
Arbuscular mycorrhizal fungi(AMF)have showed to enhance plant resistance to environmental stresses. In this study, the effects of AMF(Glomus mosseae, GM)on growth and Cd accumulation and rhizospheric soil enzyme(urease and invertase)activities of upland rice were investigated under different Cd addition levels(0, 2, 10 mg·kg-1)in a pot trail. The colonization rates of upland rice roots by GM ranged from 37%to 72%and decreased with increasing soil Cd concentrations. The mycorrhizal colonization significantly enhanced soil en-zyme(urease and sucrase)activities(ranging from 9.6%~44.5%), promoted carbon and nitrogen metabolisms in the rhizosphere, and in-creased upland rice biomass (ranging from 10.4%~57.1%), as compared with the non-mycorrhizal upland rice. The uptake and transfer of Cd in upland rice and Cd concentrations in rice grains(ranging from 26.8%~57.1%)were significantly decreased by GM inoculation.关键词
