The sequential differentiation of leaf, bract, lateral flower, sepal, petal, stamen and carpel primordia in apple buds was examined. Under favorable conditions the minimum time required for differentiation of the lateral floral primordia, the sepal, petal, stamen and carpel for the king flower was less than a week, 1, 1, 2 and 2 weeks, respectively. The progress of node formation in vegetative and floral buds before bud differentiation was shown to be a negative asymptotic curve. There was no subsequent node formation in vegetative buds. Floral buds increased in node number, during the first 3-4 weeks of development; no further increment occurred after formation of the "sepal" stage. The theory of plastochron for flower induction is discussed
