摘要:
以‘金口’芹菜为试材，在盆栽试验条件下，设置4个NaCl浓度（0、50、100、150 mmol?L-1）并接种丛枝菌根真菌（AMF），研究了AMF对盐胁迫下芹菜生长和生理指标的影响，以期为盐碱地蔬菜栽培生产提供参考依据。结果表明：随着盐胁迫程度的增加，芹菜的生长指标受到抑制的程度越来越严重，而接种AMF处理与未接种相比，其株高、茎粗、地上鲜质量和地下鲜质量受抑制程度均显著性降低，植株体内的可溶性糖、脯氨酸含量升高，其超氧化物歧化酶（SOD）、过氧化物酶（POD）和过氧化氢酶（CAT）活性均得到显著增强，而丙二醛（MDA）的积累量明显降低。接种AMF可以促进盐胁迫环境下芹菜植株的生长，缓解盐胁迫对芹菜植株的伤害。
Abstract:
In this study，celery(Apium graveolens，cv.‘Jinkou’) was used as the test material to inoculated with AMF under four NaCl concentrations (0，50，100，and 150 mmol?L-1) in pot experiment.The effect of arbuscular mycorrhizal fungi (AMF) on the growth and physiological characteristics of celery under salt stress was studied.In order to provide a theoretical basis for the cultivation and production of vegetables in saline-alkaili land.The results showed that with the increase of the degree of salt stress，the growth index of celery was restrained the extent to which more and more serious，and add the AMF treatment compared with no addition，the plant height，stem diameter，plant fresh weight and root fresh weight of suppression level were significantly lower.The soluble sugar and proline content of plant body increased，the superoxide dismutase，peroxidase and catalase activity were significantly enhanced，and the accumulation of malondialdehyde decreased significantly.AMF inoculation can promote the growth of celery plants under salt stress and alleviate the injury of celery plants under salt stress.
