摘  要：
【目的】测定杭州地区5个常见茶梅品种的抗寒性,为茶梅品种向长江以北地区推广提供科学依据。【方法】以目前杭州地区园林应用最广的5个山茶科山茶属茶梅品种立寒、朝仓、昭和之荣、冬牡丹、笑颜为试验材料,在冬季低温条件下进行相对电导率测定,并于寒害发生后进行低温半致死温度测定。【结果】5个茶梅品种均随着外界气温的降低,相对电导率呈先升高后降低的趋势;低温半致死温度处于-21～-14℃。【结论】5个茶梅品种对低温环境均具有较强的适应和调节能力及一定的抗寒能力,其中以昭和之荣的抗寒力最强。

摘  要：
[Objective]Cold resistances of five common Camellia sasanqua Thunb.varieties were determined in the present experiment in order to provide scientific references for extension of Camellia sasanqua Thunb.in northern areas of Yangtze River.[Method]Five Camellia sasanqua Thunb.varieties,viz.,Kanjiro,Asakura,Showa-no-sakae,Azuma-botan and Egao,which were the most common ornamental trees in Hangzhou City,were used as experimental materials.Their relative conductivities were determined under the low temperature conditions in winter and the semi-lethal temperature was also determined after occurrence of chilling injury.[Result]The relative conductivity of the five C.sasanqua varieties increased initially and then decreased with decreasing outside temperature,and the semi-lethal temperature was recorded between-21 and-14℃.[Conclusion]All the five C.sasanqua varieties were found to have good adaptability to low temperature conditions and with certain degree of cold resistance.
