摘要: 采用盆栽试验研究了不同浓度NaCl (0.5%和1% ) 胁迫下, 接种丛枝菌根真菌(AMF) 对
番茄生长和渗透调节物质含量的影响。结果表明: 盐胁迫下, 与未接菌番茄相比, 接种AMF番茄能显著增
加植株的生长, 促进叶片和根系可溶性糖的积累, 增加叶片可溶性蛋白含量及根系脯氨酸含量, 使植株耐
盐能力增强。接菌株可溶性糖及可溶性蛋白的增加以及根系脯氨酸的大量积累在AMF提高番茄耐盐的渗透
调节机制中具有重要的作用。

Abstract:

The effects of arbuscular mycorrhizal fungi (AMF) on p lant growth and osmotic adjustment
matter content of pot cultured tomato under NaCl stress ( 0.5% and 1% ) were studied. The results showed
that AMF-inoculation significantly increased tomato p lant growth, promoted the accumulation of soluble sugar
in leaves and roots, increased soluble p rotein in leaves and proline content in roots under salt stress, so AMF
enhanced salt tolerance of tomato plants. The accumulation of soluble sugar, soluble p rotein and root p roline
induced by AMF played an important role in osmotic adjustmentmechanism of enhanced salt tolerance in my
corrhizal tomato.
