Potential for Regulation of Plant Growth and Development
A plant, unlike an animal, has to grow and survive and yet remain in the same place throughout its life. Furthermore, it is exposed to attack by pests and diseases, competition from weeds, and may be subjected to various forms of environmental stress. In man’s attempts to help crop plants achieve their full potential, methods have been developed to control pests, diseases, and weeds; the plant breeder has produced improved varieties; and better performance is sometimes achieved by manipulating the crop by such devices as grafting and pruning. Better yields can be ensured by a balanced fertilizer program and unsuitable soil conditions can be improved by drainage or irrigation. Except in special situations, however, such as in glasshouses, it is not possible to control the weather—the main environmental factor which affects plant growth and development.
