NaCl胁迫对大黄龙船花生长及生理生化的影响
Growth and Physiological Indexes ofIxora collinea‘Gillettese How’ under NaCl Stress
摘要
Abstract
The aim was to analyze thesaltresistance ofIxora collinea‘Gillettese How’. The growth and physiology indexes in ‘Gillettese How’ seedlings were studied under NaCl stress. The results showed that the seedling growth was inhibited significantly under salt stress. The MDA and proline contents, relative electric conductivity and membrane damage increased, and they had signiifcant positive correlations with NaCl concentration. The contents of chlorophyll and soluble protein in leaf decreased and negative correlation with NaCl concentration. However, there were no significant correlation between soluble sugar content, superoxide dismutase (SOD) activity and NaCl concentration. The growth of ‘Gillettese How’ was inhibited weakly under low NaCl stress (0.2%–0.6%), but it was affected greatly under high NaCl (0.8%–1.5%) stress.关键词
