Abstract
Chickpea (Cicer arietinum L. cv. 235) plants were grown in sand culture at moisture equal to 45-50% of sand saturation capacity under greenhouse conditions. 60 d after sowing, pots were divided into four lots, leaving one as control and sand moisture content of others was brought to 25-30% (S1), 12-15% (S2) and 5-6% (S3) of sand saturation capacity, by withholding the water supply and then maintaining the required levels gravimetrically till the harvest. Relative water content of leaves and nodule water content were measured as indices of water stress. With increase in the severity and duration of water stress nitrogenase activity and nitrogen and leghemoglobin content of the nodules decreased and the ratio of leghemoglobin components I and II were changed. Nodules developed under limited water availability showed decreased branching, breakdown of the endodermis, greater compactness and decreased vacuolation of cells in the central symbiotic tissue as compared to the control.
