Seed Bacterization a Novel Prime Tool for Growth Promotion in Tomato (Solanum lycopersicum M.) under in vitro

Abstract

Beneficial microbes group of rhizobacteria such as Pseudomonas spp. and Bacillus sp. can serve as, PGPR and biological antagonists against with plant pathogens and can increase plant resistance through primed seeds. This study aimed to determine the activity of Pseudomonas spp. and Bacillus sp. in promoting germination and seedling growth of tomato plants. The native isolates the strain Pf1 recorded the increased vigour index of tomato seedlings significantly. It recorded 100 percent germination, increased mean shoot and root length of 8.26 and 14.33 cm respectively with vigour index of 2259. This was followed by EPCO16 with 98.64 percent germination, increased mean shoot and root length of 7.82 and 13.44 cm respectively with vigour index of 2097, followed by EPC 5 with 97.32 percent germination, increased mean shoot and root length of 7.63 and 13.14 cm respectively with vigour index of 2021.
