Effect of TLCV on Metabolic Parameter and Yield of Tomato

Abstract

Tomato leaf curl disease (TLCV) is the most destructive disease in Tropical and sub-tropical countries. TLCV causes distinct curling symptom of leaf in tomato crop. In the present investigation metabolic parameters viz; moisture and dry matter content, chlorophyll content, enzymatic activities, carbohydrate content, protein content and phosphorus content have been studied between infected and healthy plant parts. It was found that virus infection reduce the moisture and dry matter content of tomato cultivars. Reducing and non-reducing sugars as well as starch content observed lower in infected plants. Total and organic phosphorus content in infected samples were always higher in comparison to healthy counterparts in all stages of infection.
