Abstract:

The nematicidal/fungicidal indigenous endophytic isolates of Bacillus weihenstephanensis (TSB4), B. cereus (CLB2), B. subtilis (TSB5), B. cereus (TSB4D) and B. licheniformis (TSB4) were studied for their ability to produce plant growth hormones in vitro and to trigger the defence enzymatic activities of tomato under controlled glasshouse/natural sick field conditions. The results of the study distinctly proved that all the isolates of Bacillus spp. were capable of producing plant growth hormones viz., indole acetic acid and gibberlic acid and to trigger the defence enzymatic activities of total phenol, peroxidase, polyphenol oxidase and phenyl alanine lyase following M. incognita Infestation both under glasshouse and field conditions. Among the five indigenous isolates, the B. weihenstephanensis (TSB4) was ranking first in this regard. The biochemical mechanism of the most effective isolate of B. weihenstephanensis (TSB4) in triggering the defence enzymatic activities of tomato against M. incognita was also confirmed through native-PAGE and SDS-PAGE.
