ABSTRACT
Different carbohydrate components, viz. total soluble reducing and non reducing sugars and starch were compared in leaves of four solanaceous plants namely Lycopersicon esculentum cv. Money maker [susceptible tomato]; Lycopersicon pimpinellifolium L. [resistant tomato]; Capsicum annuum cv. "California Wonder" [pepper] and Solanum nigrum var. judaicum [Enab El-Deeb] at different intervals after inoculation with an isolate belonging to Y° group of the common strain of potato virus Y [PVY] studies indicate that i - In susceptible tomato virus infection lowered significantly the total carbohydrate content and starch content and decreased also the monosaccharide content but increased sucrose concentration. ii- In resistant tomato virus infection decreased significantly all carbohydrate fractions except only the monosaccharides. iii- In pepper virus infection lowered the total carbohydrate content as a result of decreased monosaccharides, sucrose and starch components .iv- In Enab El-Deeb virus infection also decreased the total carbohydrate as well as the starch and total soluble sugars
