摘　　要：研究了甜菜种子经不同浓度6-苄基腺嘌呤(6-BA)浸泡处理后,甜菜种子芽率、种子活力及幼苗生理生化的变化。结果表明,6-BA有助于提高甜菜种子活力、能缩短出苗时间,显著提高种子简化活力指数,以0.1 mg/L和0.5 mg/L浸种效果最好。6-BA处理种子后,对其幼苗的干重和株高有影响,同时幼苗的电解质外渗率和丙二醛含量较对照有所下降,叶绿素含量变化不显著。Seed germination rate, the seed vigor and physiological and biochemical changes of seedlings were studied with sugarbeet seeds （varieties： Xintian 14 and 15） soaked by different concentrations 6-BA （6- benzyladenine）. The results show that 6-BA improves sugarbeet seed vigor and seeds simplified vigor index, shortens the time of emergence. The effective concentrations of 6 - BA are 0.1 mg/L and 0.5 mg/L. In comparison with control 6-BA seed treatment has altered the plant dry weight and plant height while electrolyte exosmosis rate （ELR） and malondialdehyde （MDA） content are decreased, chlorophyll content of leaves does not show significant changes.
