摘要:
以3个辣椒自交系HXUY0912、HXUX1160和HXUX1123为试材，研究低、中、高浓度（0.2%、0.4%、0.6%、0.8%、1.0%）NaCl胁迫对辣椒种子萌发和幼苗生长的影响，采用隶属函数法对其耐盐性进行综合评价，研究NaCl胁迫对辣椒自交系萌发的影响，评价各参试自交系的耐盐性。结果表明：低浓度盐胁迫对种子萌发及幼苗生长无显著抑制作用，随着盐分浓度的升高，盐胁迫对3个辣椒自交系的种子萌发造成不同程度的抑制，各自交系间在种子萌发期存在明显的耐盐性差异。综合评价其耐盐性结果为自交系HXUY0912在低盐条件下耐性最好，自交系HXUX1160对中浓度的盐胁迫反应迟钝，自交系HXUX1123在各种盐浓度胁迫下表现出了较好的适应性。
Abstract:
Three pepper inbred lines（HXUY0912,HXUX1160,HXUX1123) were used as materials,the effect of NaCl stress of low,medium and high concentration （0.2%,0.4%,0.6%,0.8%,1.0%) on pepper seed germination and seedling growth,the comprehensive evaluation of salt tolerance were carried out by membership function method.The results showed that low concentration of salt stress performed significant inhibitory effect on seed germination and seedling growth while it had different inhibition effect on three kinds of inbred lines with increasing salt concentration.Besides,apparently,there was a salt tolerance variation among these inbred lines.Therefore,in an overall conclusion,HXUY0912 performed the best salt tolerance under stress of lower concentration and HXUX1160 performed dully in response to the stress of medium concentration,moreover,it was found that HXUX1123 had a better adaptability to stress of various concentration.
