摘  要:
通过对苏北地区引种栽培的4种常绿阔叶树种露地越冬时期的形态特征进行观测,测定了多个与植物耐寒性相关的生理生化指标,结合Logistic方程分析、隶属函数分析等方法,对4种常绿阔叶树种在引种栽培环境中的适应性进行了多个层面的分析和评价.结果表明:天竺桂、台湾含笑、乐昌含笑、山杜英均能够耐受苏北地区冬季平均-10~-7℃的低温,综合比较引种常绿阔叶树种的耐寒性,排序为天竺桂(栾川)>天竺桂(南京)>台湾含笑>乐昌含笑>山杜英>天竺桂(成都).因此,4种常绿阔叶树种适宜在苏北地区引种栽培.

摘  要:
Through the observation of the morphological characteristics of 4 evergreen broad-leaved tree species introduced and cultivated in northern Jiangsu during the wintering period, a number of physiological and biochemical indicators related to cold tolerance of plants were determined. Combining Logistic equation analysis and membership function analysis, the adaptability of 4 evergreen broad-leaved tree species in the introduction and cultivation environment was analyzed and evaluated at various levels. Results show that 4 evergreen broad-leaved tree species, including Cinnamomum pedunculatum, Michelia compressa, Michelia chapensis and Elaeocarpus sylvestris, can tolerate the average low temperature of-10--7 ℃ in winter in Jiangsu northern areas. According to the comprehensive comparison of cold tolerance of 4 species, the order from strong to weak is as the following:Cinnamomum pedunculatum(Luanchuan), Cinnamomum pedunculatum(Nanjing), Michelia compressa, Michelia chapensis, Elaeocarpus sylvestris, Cinnamomum pedunculatum(Chengdu). Comprehensive evaluation shows that4 evergreen broad-leaved tree species are suitable for introduction and cultivation in Jiangsu northern areas.
