摘　　要：分蘖是影响水稻穗数并进而影响其单产的重要农艺性状,是单子叶植物在生长发育过程中形成的一种特殊的分枝特性。水稻分蘖的发生是一个非常复杂的过程,自然条件、植株营养、植物激素、遗传等因素都会影响其发生。深入研究水稻分蘖发生机理,更加有效的调控分蘖发生,将会进一步提高水稻产量,对水稻生产具有重要意义。前人对水稻分蘖的发生及调控进行了大量研究,作者从形态、环境、激素、分子等4个方面对水稻分蘖发生的机理进行综述。Tiller,which affects the number of panicle and the grain production,is an important agronomic trait of rice,and also a model system for the study of branching in monocotyledonous plants.The growth of tiller is a complicated process,a lot of factors affect tiller occurs,for example,illumination,temperature,water,nutrition of plant,phytohormone and genetic.Further research on the mechanism of tiller occurs and reduction of unproductive tillers will increase the grain yield of rice.Because the observably effect of tiller on the growth and grain production of rice,the research on the mechanisms of tiller occurs and control are attract the attention of researchers all along.In this particle we summarized the mechanism of rice tiller occurs from four aspects： morphologic,entironment,phytohormone and molecule.
