Physiological Reaction of Zantedeschia hybrida to the Low Temperature Stress

This paper analyzed the resistance index of leaves by giving the low temperature to Zantedeschia hybrida at different level.The results showed that by the reducing of temperature,the relative conductivity,MDA content and Pro enzyme's competence marked increase,but SOD content's activity and the content of chlorophyll depress.The frost resisting breeds could keep high level of SOD and Pro enzyme's competence,and at low MDA content.
