摘要

背景:土壤盐分严重影响植物的生长发育。研究了抗氧化剂(β-胡萝卜素和没食子酸)叶面施用与盐胁迫对枸杞幼苗的影响。结果:25 mM NaCl盐胁迫对水稻总干重和总鲜重均有不利影响。K+含量显著降低，Na+含量显著升高。叶面施用β-胡萝卜素和没食子酸可通过调节离子吸收、降低H2O2和丙二醛(MDA)含量、提高酶抗氧化活性、酚类物质、谷胱甘肽和叶绿素含量，显著缓解盐胁迫的影响。结论:β-胡萝卜素和没食子酸处理的植物具有较高的耐盐性。

Improving the effects of salt stress by β-carotene and gallic acid using increasing antioxidant activity and regulating ion uptake in Lepidium sativum L.

Background: Plant growth and development are severely affected by soil salinity. This study was carried out to evaluate the interaction of foliar application of antioxidants (β-carotene and gallic acid) and salt stress on Lepidium sativum seedlings.

Results: Our findings revealed that total dry and fresh weight were adversely affected by 25 mM NaCl salinity stress. Moreover, K⁺ content decreased while Na⁺ content increased significantly. The foliar application of β-carotene and gallic acid significantly mitigated the effects of salt stress by regulating ion uptake, reducing H₂O₂ and malondialdehyde (MDA) content, as well as increasing enzymatic antioxidant activity, phenolic, glutathione, and chlorophyll content.

Conclusions: β-carotene- and gallic acid-treated plants had higher salt tolerance.
