Physiological and Biochemical Mechanisms of Improving Salt and Drought Tolerance in Okra Plants Based on Applied Attapulgite Clay

Attapulgite clay (AC), which is rich in good adsorption, catalysis, rheology and heat resistance, an important mineral resource. However, the roles of AC regulating stress tolerance plants have not been investigated. In this study, culture pot experiment was used to analyze effects applied into soil on growth physiological metabolism okra plants. The significantly enhanced salt drought Component analyses showed that significant increases ABA, proline, soluble protein, sugar photosynthetic pigment content, as well decreases hydrogen peroxide, superoxide anion radical malondialdehyde content were observed grown with 30 g/kg under stresses. Enzymatic indicated activities 9-cis-epoxycarotenoid dioxygenase, pyrroline-5-carboxylate synthase, dismutase peroxidase also increased These results demonstrate can alleviate damage caused by stresses, leading has potential be develop plant regulators enhance abiotic stresses
