Identification of Trichoderma Strain M2 and Related Growth Promoting Effects on Brassica chinensis L
摘要
Abstract
The research took Trichoderma strain as tested strains which isolated from the rhizosphere of healthy and high yield pepper, M2 was classified and identified by combining morphological classification with molecular identification means(rDNA-ITS sequence analysis), whose effect on growth of Brassica chinensis L. was explored, in order to provide superior strains for bio-fertilizer development. After solid fermentation of Trichoderma M2, under the condition of the greenhouse, took some research on the growth promoting effect on Brassica chi-nensis L. of Trichoderma M2. The results showed that the strain M2 was identified as Trichoderma harzianum strain. M2 had obvious effects on promoting growth, the SPAD and edible leaf number of Brassica chinensis L. Adding of 5.0í109 cfu M2 had the best effect on increasing the biological yield. Compared with CK, fresh weight and dry weight was increased by 30.26%and 20.08%respectively. Followed by inocula-tion of 5.0í108 cfu M2, fresh weight and dry weight was increased by 18.33% and 12.46% respectively. Therefore, M2 showed evident promoting effect on Brassica chinensis L., and had potential application value.关键词
