摘要
为丰富我国园林观赏植物种质的多样性,自北美引进了6个观赏豆梨品种,从生长量、耐寒性、耐热性和抗病虫害能力强弱4个方面,对各品种进行适应性研究并做了综合评价分析。结果表明:6个品种均能适应潍坊地区的环境条件,生长发育正常,其中以‘新布拉德福’豆梨生态适应性最好,‘贵族’和‘首都’两品种次之。为我国北方地区豆梨的引种栽培提供技术参考。
In order to enrich germplasm diversity of garden ornamental plants, we investigated the ecological adaptation of six Pyrus caUeryana cultivars in Weifang from the growth, cold resistance, heat resistance and the ability to resist pests and diseases. The results showed that the introduced cuhivars could adapt to the environment of Weifang and grow normally, but the growth and the ability to resist pests and diseases of ＇ New Bradford＇ was better than those of the other varieties. ＇ Aristocrat＇ and ＇ capital＇ took second place.
