Factors Affecting Flowering of Coffee

Two distinct processes should be considered when studying the relation between environmental factors and the flowering of coffee: flower-bud initiation and flower opening or anthesis. These two processes are controlled by different environmental factors. With most coffee varieties, it has been experimentally demonstrated that flower-bud initiation is a typical response to short days (10,19), one exception being the variety semperflorens which produces flower buds under any photoperiodic condition (22). Anthesis, on the other hand, depends primarily on rainfall distribution and appears to be a response to rain following a period of moisture stress (3). This chapter will review the present knowledge concerning the external and internal factors controlling flower opening, or the transition from dormancy to bud break.
