Abstract

Use of plant growth promoting rhizobacteria in managing bacterial canker disease of tomato was studied in the present work. Tomato seeds were treated with PGPR strains viz., Bacillus pumilus INR7, Bacillus pumilus SE34, Bacillus pumilus T4, Bacillus subtilis GBO3, Bacillus amyloliquefaciens IN937a and Brevibacillus brevis IPC11 were subjected for seed germination and seedling vigor. Among the PGPR strains tested, only three strains (IN937a, GBO3 and IPC11) which showed enhancement in the seed quality parameters like seed germination and seedling vigor, were further subjected for estimation of one of the defence-related enzymes, Phenylalanine Ammonia Lyase (PAL) with total phenol contents. The same three strains were recorded for maximum disease protection under greenhouse conditions. The level of PAL and total phenol contents increased significantly upon the PGPR treatment. The rate of reduction in the bacterial canker disease incidence was directly proportional to the amount of increased level of PAL and total phenol content. The possible uses of these PGPR strains in effective management of bacterial canker of tomato were discussed in the present work.
