9种丁香的引种适应性研究

Study on the Adaptability of 9 Syringa Varieties

为研究9个引进丁香品种在山东地区的适应性,对引进丁香进行生长量、物候期、耐寒性及抗病虫能力调查。结果发现,9个丁香品种能完成正常的生长发育,生长适应性强;物候期方面,表现稳定、观赏期长,观赏价值高;在耐寒性方面,除‘玛丽安’和‘荷顿’的耐寒性为Ⅱ级外,其余品种均为Ⅰ级;在抗病虫能力方面均表现为Ⅰ级。由此推断,‘麦肯’、‘莫斯加’、‘裘利’、‘沙宣’、‘瓷蓝’、‘淮敏’、‘詹姆士’适宜在山东地区进行引种栽培。

The paper aims to study the adaptability of the 9 Syringa varieties in Shandong Province. Theauthors investigated the growth, phonological period, cold endurance, and resistance to pest and disease of theintroduced Syringa varieties. It was found that the 9 Syringa varieties could grow and develop normally, theyhad strong adaptability. They had normal growth and development, a long florescence and high ornamentalvalue. Cold tolerance of‘Marie Frances＇ and‘Albert F. Holden＇reached Ⅱ level, while that of other varietiesreached Ⅰ level. The 9 Syringa varieties showed strong resistance to pest and disease. Therefore,‘ArchMckean＇,‘Krasavitsa Moskvy＇,‘Charles Joly＇,‘Sensation＇,‘Wedgewood Blue＇,‘Donald Wyman＇and‘James Macfarlane＇were suitable to be cultivated in Shandong Province.
