Under alkaline conditions sugars with potentially free aldehyde or ketone groups, reduces metal ions, so are known as reducing sugars. The physiological stress affects the reducing sugars in many plants. The physiological parameters shows that the crop plants respond to the saline, pre sowing and drought stress. The present study deals with the effect of physical stresses on reducing sugar in Eleusine coracana. The amount of reducing sugar fluctuates with the stress but crop maintains balance in reducing sugar content compared to their control, Crop shows better results under drought conditions than for other stress. There is 25-40% increase in reducing sugar is observed under 2- and 4-days drought while under presowing salt stress, in Dapoli 3, under 8mM and 30mM ,10-12 % decrease in reducing sugar is observed. The observations are conformed by analysis of variance (ANOVA), a biostatistical analysis.
