Review of Researches on Root Growth, Distribution and Physiological Characteristics of Cotton
Root morphological and physiological characteristics play important roles in cotton (Gossypium hirsutum L.) growth and development. However, root studies have been less thorough than those of above-ground studies because of difficulties in root observation. In this paper, the recent development and current status of research on the cotton root is summarized, including research methods, root growth and distribution characteristics and their influencing factors, as well as root physiological characteristics. Several problems in root studies are discussed and research prospects in this field are presented.
