Some basic concepts of physiology are presented in relation to bean cultivation, and the external and internal factors affecting crop development and production are described: the environment (edaphic and climatic factors), photosynthesis and factors that affect it (light, CO2, O, temp., wind and water) photorespiration and photoperiod. In beans a great variation exists between the different lines and var. with regard to their response to the photoperiod. Adaptation is determined by: (a) insensitivity to the photoperiod, (b) a stable growth habit, (c) insensitivity to temp. during flowering, (d) drought tolerance, and (e) tolerance to excess moisture. Growth habits in beans are determinate, indeterminate, semi-climbing indeterminate and climbing indeterminate. Other factors are described such as the period of growth and development (emergence, appearance of the 1st trifoliated leaf, flowering, complete flowering, beginning of pod formation, development of the bean and maturity). Yield components (morphological, physiological, leaf area and LAD) and simplified yield, including biological and economic yield and growth, are analyzed. Abscission is studied by plant maps and 3 ideotypes are proposed to improve yields by the selection of desirable morphological and physiological characters. (CIAT)
