类芽孢杆菌CBP-2对盐胁迫下3种植物种子萌发及幼苗生长的影响
The Effects of Paenibacillus sp.CBP-2 on Plant Seed Germination and Seedling Growth under Salt Stress
摘要
Abstract
To clarify the effects of silicon releasing Paenibacillus sp.CBP-2 on crop seed germination and seedling physiological characteristics under salt stress,typical horticultural(Chinese cabbage)and grain crop(maize and wheat)varieties were selected as test materials.The effects of inoculating different concentrations of target strains on seed germination,seedling growth indicators,and physio-logical activity changes under salt stress were studied using a culture dish filter bed germination meth-od.The results showed that compared with the control group without NaCl,the growth of Chinese cabbage,corn,and wheat seedlings was significantly inhibited under 8 g/L NaCl.Inoculating CBP-2 fermentation broth at an appropriate concentration can effectively alleviate the damage caused by salt stress to seeds and seedlings.The optimal fermentation broth concentration for strain CBP-2 to allevi-ate salt stress in different crops such as Chinese cabbage,corn,and wheat varies,with dilutions of 40 times,80 times,and 80 times,respectively.关键词
