Development of Vascular Connections Between Lateral Buds and Main Stem in Some Decapitated Plants

After decapitation of pea plants, with resultant growth of lateral buds, the thickness of vascular tissue appeared to be correlated with the growth rate of buds. Basal lateral shoots had better developed vascular strands than buds on upper parts of the plants. IAA application retarded growth of the lateral buds and inhibited their vascular connections, but all lateral buds eventually grew in spite of the IAA application
