Abstract:

Tiller is an important agronomic trait of rice, it affect the number of panicle and grain production of rice. Tiller is a special branch and shape during growth and development of monocotyledonous plants, because the tiller have an observably effect on growth and production of rice, so the research with mechanisms of tiller occurs and control are attract the attention of people all along. Occur of tiller is a complicated process, a lot of factor affect tiller occurs, for example, illumination, temperature, water, nutrition of plant, phytohormone and genetic.. In this particle we summarize the mechanism of rice tiller occurs from four aspects: morphologic, entironment, phytohormone and molecule.
