Growth Regulation and Cytological Alteration in Coriandrumsativum L. using Bioinoculant Pseudomonas putida

Abstract

PGP Rsare the rhizobacteria, playing an important role in plant growth and used in agriculture system either directly or indirectly as bio-fertilizers. Pseudomonas putida is used in the present study to inquire the effect of cytological as well as growth parameters on the coriander. A pot experiment was conducted to study the seed germination percentage and the Seed Vigor Index (SVI) of the coriander. The study showed the high percentage of seed germination and increase in shoot and root length of the young growing plant. Seed vigorousity was found more in treated plants with 889.7505 compared with non- treated plants (control) 213.8265. Some sprouted seeds were further used for cytological observation and found more cell division i.e. Active Mitotic Index % (AMI %) in cells treated with bacteria as 14.81% followed with control only 12.30%.
