Effect of environmental factors on biochemical properties of tomato leaf curl virus infected leaves of tomato

Abstract

Tomato is a commodity of great economic importance in the world. One of the destructive viral diseases known as Tomato leaf curl virus belongs to Begomovirus has negatively impacted on tomato production in world. Tomato leaf curl virus widely distributed in the tomato crop and transmitted through whitefly in nature. Virus duplicates inside the host and altered various biochemical and physiological process. In this project, it was observed that the photosynthesis rate had positive correlation while lycopene and starch content (max temp) were negatively correled in relation to environmental variables when compared with healthy plants. In case of phenolic compounds, it was increased as temperature increased and vice versa. There is no effect of relative humidity on chlorophyll contents in infected plants.
