In January of 1990, 72 axillary bud were labeled on each of 6 carambola (Averrhoa carambola L.) trees. Six (6) buds per tree were harvested on a monthly basis and examined to determine their developmental state, which was classified as: reproductive, vegetative or undifferentiated. The number of reproductive buds peaked in July, October and November. The percentages of buds being reproductive during these 3 months ranged from 86% for October to 94% for November, with July intermediate at 91%. Vegetative bud production peaked during the period from February through June with 45% of buds vegetative, and again in August with 33% vegetative and December with 39% vegetative. More than 50% of buds examined were undifferentiated during the period from December through April and again in September. Periods with high percentages of undifferentiated buds preceded times with high percentages of either reproductive or vegetative buds. When a high percentage of buds were reproductive, the percentage of both vegetative and undifferentiated bud was low.
