Resumen:
Agronomy is the science and technology of producing and using plants for food, fuel, and fiber. It presents agriculture from an integrated, holistic perspective (American Society of Agronomy, 2014). Crop physiology studies the structure and functioning of crops in relation to productivity and quality product for different uses. Also, in recent years, it is considered that efficiency of plant breeding could be increased by applying knowledge and tools from crop physiology. Plant breeding aims to adapt the genetics of plants to develop crops better adapted to human needs. Compared to previous reviews about sunflower crop physiology, this chapter examines together crop physiology and agronomy giving the basis for the crop management and genetic improvement of sunflower from a physiological point of view. Also, some differences among the physiology of sunflower and other crops will be specially highlighted in this chapter. First, current knowledge on sunflower physiology (crop phenology and growth) is presented. Emphasis is given to determination of yield and product quality as well as ecophysiological components underlying its determination. Second, the effect of some main abiotic and biotic stresses affecting sunflower crop growth, yield, and ecophysiological components around the world are given. Nutrients and water crop requirement are briefly reviewed. The effects of some of the main weeds, pests, and diseases affecting sunflower yield and ecophysiological components around the world are presented. Third, the basis for adjusting some main crop management practices that could help to obtain good yields and quality product with an efficient use of environmental resources in a framework of sustainable production are conferred. Finally, the main avenues for a physiological-based management and genetic improvement of the sunflower crop are given.
