【 摘 要 】
Horsegram plants were raised in terule soil in earthen pots and subjected to various durations of water stress (7, 14 and 21 days). Total nitrogen contents were reduced in water-stressed plants but differently in different plant parts. Nitrate content and nitrate reductase activity decreased with stress. This species possesses a good capacity for accumulation of free proline under water stress. Analysis of amino acid composition also revealed marked changes in the levels of various amino acids in water-stressed plants. Accumulation of γ-aminobutyric acid in water-stressed plants was observed.
