Abstract
An anatomical study was made of buds on current season shoots of the plum var. ‘Gulfruby’ grown at the Royal Ang-Khang Station in the North Thailand.
Buds were examined at 1 week intervals during 1986. The study showed that the axillary bud consisted of 3 small flower buds.
The dome-shaped meristem, covered with 5–10 layers of bud scales, consisted of 2–3 tunica layers and corpus cells (center primordia). The lateral sides of meristem formed small groups of initial cells which later give rise to a cup-shaped receptacle or a protuberance.
The upper part of the cup-shaped receptacle forms many initial cells which arrange in a row and later develop to stamens, petals, and sepals.
The central primordium gives rise to the ovary.

The central primordium gives rise to the ovary.
Floral initiation began simultaneously in almost every axil of the shoot studied after September.
