Abstract

Chickpea plants were subjected to waterlogging for a period of 5 and 10 days during the vegetative, flowering and pod-filling stages. After release of stress, plants were sprayed with 10 and 100 mg l−1 of gibberellic acid (GA3). Waterlogging decreased the dry weight of leaf, stem and root at all the stages. GA3 at 100 mg l−1 alleviated the effect of 5 days of waterlogging on dry weight of leaf and stem given at vegetative stage, but only partially on the effects of 10 days of waterlogging. Application of GA3 decreased the root dry weight. Waterlogging significantly decreased the number of flowers and pods and the weight of pods and seeds. Its effect at pod-filling stage was more deleterious than at other stages. Both the concentrations of GA3 increased the number of flowers, pods and weight of pods and seeds and alleviated some of the deleterious effects of waterlogging.
