Abstract: The results of the low temperature(-8 ℃,-15 ℃)treatment of the 1~2 a seedlings of Fukiencypress demonstrated that,when treated for 24 hours,the contents of chlorophyll and proline in plants increased in comparison with the control of natural low temperature at -4 ℃ with the root vitality decreasing.Moreover,the differences among provenance were quite marked.The increase ratios in chlorophyll and proline were that the provenance of Xianyou and Nanjing were higher than that of Dehua while the decrease ratios in root vitality were Xianyou
