Abstract: This paper reviews the research progress on the inducement of cotton fiber in vitro, including the factors affecting cotton fiber differentiation and growth, and the mechanism of cotton fiber development. Cotton fiber in vitro can be induced mainly from ovules or from the callus, and was regulated by plant growth substances and environmental factors. This paper discussed the problems about culture of cotton fiber in vitro and the potential application of culture of cotton fiber in vitro.

Key words: Cotton fiber in vitro, Cotton fiber development, Mechanism of development
