栎类新品种‘传奇’和‘鸿运当头’
Quercus rubra ‘Chuanqi’ and Q. palustris ‘Hongyundangtou’: two new cultivars of Quercus
【目的】筛选观赏性强的栎类优良新品种,为我国温带地区造林绿化树种的推广提供参考。【方法】通过实生选种方法,筛选出特异单株进行嫁接繁殖,并进行DUS测试。【结果】‘传奇’红栎新品种干型好,叶片硕大,秋季红叶期达25 d左右;‘鸿运当头’沼生栎树干通直,新芽红褐色,秋季红叶,12月中旬叶完全落尽。【结论】‘传奇’和‘鸿运当头’是观赏性状优良的栎类新品种,可作为园林绿化景观树种加以推广应用。
【Objective】Quercus species are important forest trees and the selection of elite new cultivars for ornamental application is of great significance for the popularization of oak afforestation. 【Method】Superior individuals were selected from seedlings and subsequently propagated by grafting techniques. Finally, distinctness, uniformity and stability (DUS) test was carried out for the selected individuals. 【Result】Q. rubra ‘Chuanqi’ had good performance with large leaves, graceful tree gesture, and a relatively long period with red leaves in Autumn for approximately 25 days. Q. palustris ‘Hongyundangtou’ possessed a straight trunk, reddish-brown buds, as well as red leaves in autumn. Its leaves completely fell off in mid-December. 【Conclusion】The two cultivars have excellent ornamental properties and they can be planted and applied for landscaping.
