Abstract:

Endophytes are the micro-organism which shares the life long relation with the host. The bacterial endophytes promotes the growth directly and indirectly by several mechanisms. Keeping in mind, the present investigation has been carried out to evaluate the bacterial endophytes for their plant growth promotion in vitro condition. Four screened bacterial antagonists viz; SVC 11, BE 1, NGB 21 and M1W1 were evaluated for the germination and the vigour of French bean, brinjal and rapeseed mustard seeds. The bacteria were used individual as well as in consortium mode on the respective seeds. The result revealed that the seeds of French bean and brinjal treated with isolate NGB 21 as best in terms of germination (91.11% and 84.44% respectively) and vigour (3270.88 and 1094.96 respectively) followed by BE 1. Isolate SVC 11 showed the highest vigour (630.51) at 21st day and germination (84.44%) followed by the isolates NGB 21 and BE 1 in rapeseed mustard. The root length and shoot length were significantly higher in French bean as compared to brinjal and rapeseed mustard. Statistically the germination percentage and the vigour index was found to be significant. The result showed that all the screened potential bacteria has the best plant growth promoting ability as compared to the other crop seed tested. Hence, the microbial consortia could be evaluated further under field conditions to developed consortia against major vegetable pathogens of Meghalaya.
