Effect of Phosphate and Salt Sources on the Growth of Fusarium oxysporum f.sp. coriandrii causing Wilt of Coriander (Coriandrum sativum Linn.)

Rajiv Karpe

Abstract: Proper nutritional source required for the growth and development of the pathogen. Phosphorous is one of the most important and essential nutrition. It is an important component of genetic material and cell membrane. The present investigation was conducted to study the effect of phosphate (Potassium dihydrogen orthophosphate, Sodium dihydrogen orthophosphate, Amonium dihydrogen orthophosphate) and salt (Sodium chloride, Potassium chloride, Calcium chloride, Cobalt chloride) source on growth of Fusarium oxysporum f. sp. coriandrii. The salts favour the growth of fungi; however, some salts inhibit the growth. For this study wild sensitive and highly resistant isolate were selected. It was observed that, there was variation in the mycelial growth of the sensitive and resistant isolate on the different sources of phosphate and salt. It was observed that resistant isolate always showed higher growth rate as compared to sensitive isolate. Maximum growth of both the sensitive and resistant isolates observed on Potassium dihydrogen orthophosphate.Potassium chloride salt showed highest growth of both the sensitive and resistant isolates followed by Sodium chloride. Calcium chloride appeared to be stimulant, while Cobalt chloride salt slightly inhibit the growth of sensitive and resistant isolates of Fusarium oxysporumf. sp. Coriandrii.
