Seedlings of dwarf and tall varieties of pea and bean, growing in John Innes Compost No. 2, were studied in relation to the effects of decapitation, indole-3-aeetic acid (IAA), and gibberellic acid (GA3) on axillary bud growth. In all varieties, GA~ antagonized the inhibitory influence of IAA on bud
