S ummary Seasonal variations in apical dominance, maximal in summer and minimal during winter, were noted in eucalypt lignotubers. Temperature variation was more important than photo‐period in affecting seasonal variation of apical dominance. The concentrations of growth‐promoting and growth inhibiting substances in the leaves were correlated with seasonal variation suggesting that both have a role in apical dominance. Decapitation studies indicate that amounts of mineral nutrients and carbohydrate do not prevent dormant bud development.
