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。 The effects of arbuscular mycorrhizal (AM) fungi on the growth and leaf ion content of soybean Glycine max were studied under salinity conditions. The results showed that K + content and K / Na ratio of leaves inoculated with Glomus mosseae were significantly higher than those in the control, while there was no significant difference in Na + content. G.mosseae significantly increased soybean plant growth, this effect with the salt concentration increased. The results showed that AM fungi increased the salt resistance of soybean under salinity condition with its increase of K + absorption and transport.
