A study was conducted to evaluate the response of hot pepper (Capsicum annuum L.) to foliar applied glycinebetaine (GB) under water stress condition. Three varieties of hot pepper eg Arka Lohit, Pusa Jwala and Arka Haritha were subjected to water stress at flowering stage. The plants applied with GB had the greater plant height, leaf area, fruit fresh and dry mass under water deficit conditions. GB application increased the PN under water defi cit condition. It was attributed to an improvement in stomatal conductance under water stress. There was a varietal difference in invertase activity and total sugar contents to GB application under water stress. Higher yield and better water use efficiency (WUE) were found in GB applied plants. The plants treated with GB 10 days before and at the time of imposing water stress (T2) responded better. The results suggested that exogenous GB ameliorates the negative effects of water stress in tomato.
