Screening the Effect of Burkholderia glumae on Seed Germination and Seedling Growth of Rice (Oryza sativa L.)

The increasing prevalence of diseases like Burkholderia glumae-produced bacterial panicle blight has an influence on rice production worldwide. In rice plants, the symptoms caused by the pathogen include browning of the leaf sheath, grain rot, and seedling rot. It is observed that the pathogen enters the plant through contaminated seeds and environmental sources of the microbe. The present study analysed the effect of B.glumae on seed germination and root- shoot growth under control condition, and also the screening of different varieties against BPB under glasshouse condition.In all the studied varieties growth responses were varied whereas healthy seeds showed maximum responses followed by artificially infected and naturally infected seeds respectively for root and shoot growth.
