| 摘 要： | 以福湘佳玉辣椒为试验材料,研究低温胁迫下喷施水杨酸、多效唑和甜菜碱对辣椒幼苗植株形态和生化指标的影响.结果表明:适宜浓度的诱导剂处理均能减轻辣椒幼苗的低温伤害程度,提高幼苗壮苗复合指标值;诱导剂处理幼苗叶中的叶绿素、可溶性糖、脯氨酸含量和过氧化物酶活性均高于对照植株,呈先升后降趋势,各诱导剂处理叶绿素、可溶性糖含量的最大值分别比对照高25.93%和61.54%,脯氨酸含量和过氧化物酶活性的最大值分别为对照的1.93倍和2.34倍;相对电导率与丙二醛含量均低于对照植株,呈先降后升趋势,相对电导率与丙二醛含量的最小值分别比对照减少了33.44%和79.31%;3种诱导剂中以水杨酸的抗寒效果较好,多效唑最差,且以7.5 mmol/L水杨酸处理的效果最佳.

| Abstract: | Effects of three different inducers on plant morphologic characteristics and biochemical parameters of Fuxiangjiayu,a strain of Capsicum annuum L.,were studied.The results showed that inducer treatment under suitable concentration could decrease cold harm and improve seedling index of pepper seedlings.Content of chlorophylls,soluble sugar and proline and POD activity in leaves from inducer treatment group were higher than that from CK,which characterized by ascending at first and descending at last.The maxi... |
