| 摘 要： | 紫色辣椒新品系(YN99007)在5种不同NaCl浓度(0.0%、0.5%、1.0%、1.5%、2.0%)处理下进行发芽试验(以日本天鹰椒作为对照),研究各浓度下的发芽率、发芽势、发芽指数、过氧化氢酶(catalase,CAT)活性及根系活力等指标.结果表明:NaCl浓度范围为1.0%～1.5%时,紫色辣椒YN99007的发芽率、发芽势和发芽指数高于对照品种;而其芽中的过氧化氢酶活性及根系活力均低于对照品种,但高盐浓度下YN99007的两个指标值下降缓慢.

| Abstract: | Purple Chili Line YN99007 was treated to germinate with Five different concentrations of NaCl(0.0% , 0.5% , 1.0% , 1.5% and 2.0% ) ,using Japan Tian Ying as a check, the results showed germination percentage, germinating viability,germination factor and germination height on height of chili YN99007 were higher than that of CK when the concentration of NaCl changed from 1. 0% to 1.5% ,but roots activities and catalase activities were lower than CK Under higher NaCl concentration, the two physiologicd indexes of YN99007 declined much more slowly. |
