Decrease in soil water potential during vegetative and flowering stage
s of two cultivars of pipeon pea (Cajanus cajan) caused higher decreas
e in relative water content in cv. ICPL-151 than in CV. H-77-216. Both
cultivars showed partial recovery during rehydration. Cv. H-77-216 al
so accumulated more proline and carbohydrates during stress and showed
better drought tolerance than cv. ICPL-151.
