【摘要】 盐渍条件下研究了丛枝菌根(AM)真菌对大豆Glycine max植株生长和叶片离子含量的影响。结果表明,接种摩西球囊霉Glomus mosseae处理的叶片K+含量和K/Na比显著高于对照,而Na+含量无显著差异。G.mosseae显著增加了大豆植株生长量,这一效应随盐处理浓度的提高而增大。表明盐渍条件下AM真菌提高大豆抗盐性与其增加K+吸收和运输有关。更多还原

【Abstract】 Effects of arbuscular mycorrhizal (AM) fungus Glomus mosseae on growth and ionic content of soybean Glycine max plants were investigated under saline conditions. Results showed that the fungus significantly increased potassium content and K/Na ratio in the leaves, while sodium content was not significantly affected. Biomass of soybean seedlings inoculated with G. mosseae was significantly higher than that of the controls (without inoculation) under NaCl stress, and the stimulating effect increased with the increase of salt concentration. These results suggest that the enhanced growth and salt tolerance of soybean seedlings resulted from AM fungi are related to the increase of K+ uptake and translocation in the plants.更多还原
