Short communication. Nitrate reductase activity in roots and leaves of chickpea cultivars under salt stress

N. Garg, R. Singla

Abstract


Four chickpea cultivars (CSG 9651, BG 267, CSG 8962 and DCP 92-3) were grown to maturity under salinity conditions of 0, 4, 6 and 8 dS mE-1. Nitrate reductase activity decreased progressively with increasing salinity, although variation was seen between the cultivars. Cultivar CSG 9651, a kabuli or Mediterranean type, appeared to be the best adapted to saline stress, maintaining growth and showing efficient nitrate reduction under these conditions.
