Effects of Growth Promoting Microbes on the Growth of Tomato Seedlings
The effects of growth promoting microbes on growth and qualities of tomato seedling were studied.Bacillus megaterium,B.subtilis,Trichoderma longibrachiatum,B.mycoides and T.ghanense were applied to the roots for 4 times after breeding,and water was used as control.The indexes were tested including sprouting,growth and resistance,and comprehensive confirmation was made via membership function evaluation method.The results showed that B.megaterium,B.subtilis and T.ghanense could promote plant growth.Compared to the control,the dry weight was increased by 22.9％,45.7％and 25.7％respectively,and it was improved by 89.0％,61.76％and 41.3％in root activity.Meanwhile,POD,SOD and CAT activity of seedlings had significantly increased,and MDA content had decreased.The cold tolerance of seedlings was enhanced in winter.According to the comprehensive comparison,B.megaterium,B.subtilis and T.ghanense had better growth-promotion effect on the cultivation of tomato seedlings.
