摘要: 采用抗冷性强的东乡野生稻(东野)和对低温敏感的6225两个籼稻品种。发现稻苗的抗冷性与低温期间内源脱落酸(ABA)含量上升及赤霉素(GA1)含量下降均有密切关系。东野的抗冷性比6225强,可能是因为其内源ABA、GA1水平对低温的响应比6225迅速,东野的ABA/GA1比值在低温24h时就已达到最大值,而6225直到低温120h才上升到最大值。

关键词: 水稻, 冷胁迫, 脱落酸, 赤霉素

Abstract: Two varieties of rice were used.One is Dongxiang wild rice (Dongye)(Oryza sativa f.spontanea Roschev) which is chilling resistant,and the other is 6225(Oryza sativa indica)which is chilling sensitive.The results indicated that the increase of ABA content and the decrease of GA1 content are greatly related to the chilling resistance of the rice seedlings.The reason of high chilling resistance of Dongye is that its ABA and GA1 levels have a much prompter response than that of 6225 to chilling stress.
