IPT（Isoprothiolane）又称稻瘟灵,被认为能有效促进植物发育并提高其抗性。为了研究IPT对烟草（Nicotiana tabacum）种子萌发、幼根发生及幼苗生长的影响,从而为其在种子加工及包衣方面的应用提供理论依据,本研究通过不同浓度的IPT处理非逆境条件下的烟草种子和幼苗,证明1～10mg/LIPT可以显著促进种子萌发及胚根的发生,增加烟苗侧根的发生,烟苗长势良好;而IPT浓度过低或过高都不表现促进作用。

IPT （Isoprothiolane） has been proved to improve the development and resistance of plant.In order to offer a theoretical basis for the processing and pelleting of tobacco seeds,this paper compared effects of different concentration of IPT on seeds germination,seed-roots development and seedings growth of tobacco.The results suggested that the concentration range of IPT such as 1～10 mg/L could obviously improve tobacco seed germination,seed-roots development and seedings growth.The concentration of IPT was not affect...
