Abstract: Alternaria alternata is the causal organism of leaf and pod blight disease of radish. A pot experiment was conducted under natural conditions at botany department of Feroze Gandhi college, Raebareli to study the effect of its infection on the cellular sugar contents in leaf tissues of Raphanus sativus L. var. Mino Early. 40 days old radish plantlets were inoculated with 15 days old culture of A. alternata. Thereafter, the total soluble sugar, reducing sugar and nonreducing sugar were estimated in healthy and diseased tissues and also in the tissues intervening in between two spots 20 and 40 days after inoculation (DAI). The total soluble sugar and non-reducing sugar decreased due to infection on both 20 and 40 DAI in diseased and intervening tissues. On the other hand, the reducing sugar increased in these tissues as compared to healthy ones. In all the three tissues, all the three biochemical constituents decreased with the increasing age of plants.
