摘　　要：以滇海水仙花为试材,研究了高温胁迫对滇海水仙花的生长及生理指标的影响,探讨了滇海水仙花的耐热性。结果表明:滇海水仙花是不耐热的植物,其对高温的适应性不强,植株适宜生长的最高温度为28℃;短期内温度达到33℃也可以生长;但是温度达到38℃时,滇海水仙花就会表现出生长不适应,植物叶片中的丙二醛、脯氨酸、可溶性糖含量均会明显的增加;而温度达到43℃时,整株植物就会枯死。Taking the Primula pseudodenticulata Pax.as experimental material,the effect of high temperature stress treatment on growth and physiological indices of Primula pseudodenticulata Pax.were studied,in order to explore the heat tolernance of Primula pseudodenticulata Pax..The results showed that the hot tolerance of Primula pseudodenticulata Pax.was much weakness.The highest temperature for it was 28℃.It could grow at the temperature up to 33℃in short time.The MDA content,proline content and the soluble sugar content of Primulapseudodenticulata Pax.leaf were obviously increased when the temperature was up to 38℃.The plant would be dead under 43℃.

关 键 词：滇海水仙花 耐热性 高温胁迫
