摘要: 以南京地区引种的5个常绿阔叶树种为研究对象,在越冬期间出现罕见冰雪灾害(2008年1月上旬至2月上旬)天气条件下,测定了不同树种抗寒性指标变化趋势。结果表明:不同树种的抗寒性指标对低温变化的响应存在差异,大叶冬青抗寒性指标随低温变化响应迟缓;深山含笑抗寒性指标随低温变化响应敏感;阔瓣含笑、亮叶含笑和乳源木莲对低温响应特征介于两者之间。抗寒性综合评价为:乳源木莲、阔瓣含笑较强,深山含笑、亮叶含笑次之,大叶冬青较弱。

Abstract: In this paper, the authors have chosen five evergreen broadleaved tree species introduced to urban area of Nanjing and investigated the changes of their cold resistance indices during over wintering with infrequent icesnow weather from early ten days of January to early ten days of February, 2008. The results showed that the response to low temperatures of these species varied. The cold resistance indices of Ilex latifolia Thumb.respond slowly to low temperature. The cold resistance indices of M.maudiae Dunn respond quickly to low temperature. The cold resistance features of the other three tree species are between those of Ilex latifolia and M.maudiae Dunn. Integrated evaluating results revealed that coldresistance from strong to weak were MangLietia yuyuanensis Law and Michelia platypetala, M.maudiae Dunn and Ichelia fulgens Dandy, Ilex latifolia Thumb.. Severe icesnow disaster during over wintering may influence the changes of cold resistance and phenological characteristics of tree species.
