| 摘 要： | 在遮雨网室以辣椒品种串串香、世纪红作为供试材料,研究不同抗干旱能力的辣椒品种对干旱胁迫的生理生化效应.结果表明,随干旱胁迫的加剧,辣椒叶片的叶绿素(Chl)含量呈现下降趋势,脯氨酸(Pro)和丙二醛(MDA)含量呈增加趋势,而超氧化物歧化酶(SOD)和过氧化物酶(POD)等保护酶活性则先升高后降低.品种串串香比世纪红有着相对较高的Chl含量、Pro含量及SOD 和POD活性(或活性的增幅),相对较低的MDA含量,表明串串香抵御干旱胁迫的能力相对较强,世纪红则相对较弱.

| Abstract: | Chuanchuanxiang and Shijihong were used as the materials to study changes of some physiological indexes under drought stress in high complete hyocaust.The results indicated that with drought stress prick up,the chlorophyll content always decreased; the free proline and MDA content always increased; the protective enzyme (SOD and POD) activities increased at first and then decreased.Chuanchuanxiang kept great relative chlorophyll content,free proline content and protective enzyme (SOD and POD) activities,and kep tlittle relative MDA content,however,Shijihong was opposite.It indicated that Chuanchuanxiang had the greater ability to resist drought stress while Shijihong had the less ability to do it. |
