4个国外接骨木属种质资源引种与生物学特性研究

为探讨4个接骨木品种在河南省郑州地区的引种表现及适应性,2015—2019年定期观测引种的‘金叶’、‘金羽’、‘花叶’、‘紫云’4个国外接骨木品种,采用层次分析法进行性状评价。研究结果表明,露地栽培中,引种的4个接骨木品种均可在郑州地区正常生长、开花、结果。4个接骨木品种均生长健壮,枝繁叶茂,花期较长,较耐低温。以观赏性、适应性、生长特性权重分配分别为0.4、0.3、0.3进行综合分析评价,综合分值表现为‘金叶’接骨木>‘花叶’接骨木>‘金羽’接骨木>‘紫云’接骨木。由此可见,4种接骨木均具有较高的观赏价值和适应性,可广泛用于郑州地区城市园林绿化和美化。

The Introduction and Biological Characteristics of Four Foreign Sambucus Germplasm Resources

To explore the introduction performance and adaptability of four elderberry varieties in Zhengzhou, Henan Province, four foreign elderberry varieties named ‘Aurea’, ‘Plumosa Aurea’, ‘Variegata’ and ‘Thunder Cloud’ were regularly observed and the analytic hierarchy process was used for character evaluation for five consecutive years from 2015 to 2019. The results showed that the four elderberry varieties could grow, blossom and fruit normally in Zhengzhou open field cultivation. All the four elderberry varieties were robust, flourishing, long-blooming and resistant to low temperature. The weight distributions of ornamental, adaptability and growth characteristics were 0.4, 0.3 and 0.3 respectively for comprehensive analysis and evaluation. The comprehensive score was shown as ‘Aurea’ > ‘Variegata’ >‘Plumosa Aurea’ > ‘Thunder Cloud’. It shows that the four elderberry varieties have high ornamental value and adaptability, and they could be widely used in Zhengzhou urban landscaping and beautification.
