Summary. The effects of 2,4-D, 2,4,5-T, IAA and GA on the germination behaviour of one-seeded pods of Psoralea corylifolia L. were studied. For each chemical, inhibition of germination of acid-scarified pods increased with increase in concentration. The inhibition was irreversible and led to death of the seed in the pod. Morality, expressed as percentage of dead pods, was highest for 2,4,5-T and IAA and lowest for GA. Impermeable or ‘hard’ pods were unaffected by the treatments. Though acid-scarified pods were significantly damaged by an 8 h chemical treatment, weathered pods were unaffected by treatments of less than 30 h duration. After scarification, dry pods were more susceptible than pre-imbibed ones. Rates of water uptake were determined for pods of both categories.
