Effect of Salt Stress on Anti-adversity Physiology of Baccaurea ramiflora Seedlings
摘要
Abstract
In order to understand the effects of salt stress on the growth of Baccaurea ramiflora seedlings,the physiological mechanism of stress resistance were studied treated with different soil salt concentrations(0.05%,0.1%,0.15%and 0.2%).The results showed that salt stress stimulated the adaptability of B.ramiflora seedlings,especially at low salt concentration(0.05%),soluble sugar content and peroxidase activity increased significantly.When the salt concentration reached 0.1%,the soluble protein content increased significantly.The content of malondialdehyde increased significantly at 0.15%salt concentration.The content of free proline and flavonoids showed significant accumulation at 0.2%salt concentration.In the initial phase(1st week)of salt treatment,peroxidase activity responded rapidly,and other indicators changed significantly after 2 weeks.Some indexes,such as free proline and soluble protein contents and peroxidase activity,increased at first and then decreased with the treatment time.So,it was of great significance for breeding salt-tolerance of B.ramiflora and developing salt-tolerant crops.关键词
