NaCl溶液胁迫下促生菌对向日葵种子生长的影响
Effect of PGPR under the Stress of NaCl Solution on the Sunflower Seedling Growth
摘要
Abstract
[Objective]The PGPR-uw4 under the stress of NaCl solution affecting the sunflower seed growth was measured. [Method]The sun flower seeds were planted in the pots filled with sand after they were soaked in the PGPR-uw4 suspension solution and fully watered once two days. And the physiology and ecology index of the seedling was measured after the 30th day. [ Results ] The results indicated that the germination, shoot height, root length, dry weight as well as fresh weight and other ecological indexes of the sunflower under the stress of certain concentration of salt was decreased and the PGPR-uw4 could lighten and reduce the effect caused by salt. The content of sugar,peroxidase vitality and the content of malonaldehyde in sunflower leaf under the stress of NaCl solution were increased at different degrees,however, the two former physiological indexes could be obviously raised but the content of malonaldehyde was reduced while the PGPR-uw4 was added. [ Conclusion ] The PGPR-uw4 could lighten and reduce the inhibition from the salt stress to sunflower seed growth.关键词
