Dormancy of buds and seeds is a well known and common phenomenon in the plant world. It is of interest because it has not yet become understandable. The dormant tissue has available to it by definition all of the environmental conditions of temperature, water supply, nutrition, etc., required for growth. The dormant tissue is alive, it respires, and in some cases grows very slowly in size (10). Yet a dormant tissue lies idle; it does not grow normally. There is within the dormant tissue some factor or mechanism which restricts growth and cell multi plication.
