| 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. |
