北京地区大山樱引种的气候适应性研究

Study on the Climate Adaptability of Introduced Prunus Sargentii in Beijing

通过比较大山樱(Prunus sargentii)在引种地北京和原产地北海道地区不同生长发育阶段主要气候差异,发现北京地区水分条件差,休眠-生长过渡期气温波动变化大,生长期的高温,是大山樱引种的主要气候限制因子,并有针对性地对大山樱引种及其养护管理提出建议.

By comparing the differences of main climate factors in different growth stages of Prunus sargentii between Beijing（introducing area） and Hokkaido（place of origin）,it indicates that the main climate limiting factors of the introduction Prunus sargentii to Beijing are the relatively low temperature in the transition period of the seed dormancy to growth,the relatively high temperature of active growth phase and the different moisture conditions.The article also provides suggestions to the introduction,maintenance and management of Prunus sargentii in Beijing.
