Keywords:: Primula pseudodenticulata Pax.; heat tolerance; high temperature stress

Abstract:: 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 Primula pseudodenticulata Pax.leaf were obviously increased when the temperature was up to 38℃.The plant would be dead under 43℃.
