黄秋葵苗期的盐胁迫反应及耐盐阈值分析
Response of Orka to Saline Stress and Analysis of Salt Tolerance Threshold at Seedling Stage
摘要
Abstract
[Objective] To study the response of orka to saline stress and salt tolerance threshold at seeding stage.[Method] Pot experiments were carried out to study the effects of coastal saline alkali soil on growth of okra,salt tolerance index and salt tolerance threshold in the seedling stage of okra were determined through correlation analysis and regression analysis.[Resuh] Plant height,stem diameter,leaf numbers,root length aboveground and underground dry weight were effected,which plant height and stem diameter remarkably decreased,but the impact of leaf numbers was minimal.When salt concentration was higher than 0.4％,with the soil salt cocentration increasing,the dry mass of orka remarkably declined.The dry mass of aboveground was determined as salt tolerance index of orka,the salt tolerance threshold was 0.491％.[Connclusion] Okra has strong salt tolerance,which is suitable for planting in hght and moderate saline alkali area.关键词
