由我院丁世民教授主持研究的安妮玉兰(Magnolia’Anne’)和简爱玉兰(Magnolia’Anne’)2个灌木玉兰品种通过了山东省林木品种审定委员会的良种审定。课题组从北美地区引进了安妮玉兰、简爱玉兰等6个灌木玉兰品种,进行了观赏品质、生物学稳定性和全方位驯化研究,通过适应性评价、观赏性评价以及抗逆性试验观测,筛选出了适应我国北方气候条件,具一定抗逆性且适合广泛推广的2个优良品种。以筛选出的优良品种为繁育材料,进行了系列扦插、压条与离体快繁等技术研究,繁育出的优质苗木在我省及省外部分地区进行了区域试验,效果良好。
Magnolia’Anne ’and Magnolia’Anne’, two shrub magnolia cultivars under the leadership of Professor Ding Shimin of our institute, passed the thoroughbred validation of the Shandong Forest Variety Certification Committee. The research team introduced 6 shrub magnolia cultivars from North America including ornamental quality, biological stability and omni-directional domestication. By adaptability evaluation, ornamental evaluation and stress resistance test, The two excellent cultivars, adapted to the climatic conditions in northern China and having a certain degree of resistance, are suitable for widespread promotion. A series of cutting techniques such as cutting, pressing and in vitro propagation were conducted with the selected fine varieties as breeding material. The high quality seedlings were bred in the region of our province and some provinces outside the province for good results.
