- Abstract
Cultural characteristics viz., colony count, colony colour and colony shape of Ralstonia solanacearum on different period of time were studied in vitro using eight culture media. Highest average colony count was recorded on triphenyl tetrazolium chloride agar (65.33), white fluidal colonies with spiral pink centre and the minimum average colony count was recorded on yeast extract chalk agar (41.50) with irregular yellow color colonies. The bacterium showed positive reaction for solubility in KOH, production of catalase, motility test, hydrolysis of starch & casein and negative reaction for gram staining.
