Axillary bud primordia of wax-apple differentiated from the epidermal and the sub-epidermal cells located at the adaxial side of the stem apex. Two other buds were added on each axillary bud of the maturing current shoots. Most of the axillary buds did not sprout and became latent buds More sub-axillary buds were differentiated on each leaf trace and developed into group of latent buds.
A manifold, growth habit was noted in wax-apple and sigmoid growth curve in stem or leaf. The basal latent buds without leaf attached and the terminal buds had higher percentage of flushing and flowering than the axillary buds with leaf attached. The latent buds were in vegetative stage and characterized by two obvious tunica layers, slowgrowing rib meristem and many pairs of leaf primordia. No sign of reproductive growth in these buds was, noted prior to or at the beginning of flooding However, some buds had entered the evocational period after one month of flooding and the meristematic activity in the buds increased, the zonation disappeared, and the axillary meristem initiated and elongated precociously. The enhanced activity resulted in the sprouting of the latent buds and the formation of the inflorescence primordia Floret primordia initiated acropetally on each inflorescence but basipetally on each cyme unit. Sepals, petals, stamens, and pistils initiated sequentially on each floret primordium. The epigynous flower was composed of ovarian tissue, hypanthium and appendicular tissues.
