t the outset it is important to understand that the growth and development of the coffee bush is complex and encompasses a variety of anatomical, morphological, physiological and biochemical processes. Events Like shoot and root growth, hard wood formation, flower initiation, pollination, fertilization, embryo development, and fruit ripening, each of these processes, is a culmination of a series of events, many of which are microscopic.
All these processes in turn are governed by a particular set of environmental conditions. In fact plant physiologists are certain about the influence of environment on the phyto hormones and biochemical processes during growth and differentiation of the coffee bush.
