摘要
2009年9月从甘肃兰州引进10个6年生紫斑牡丹品种,种植于辽宁农业职业技术学院内,通过对其物候期、枝条生长量等指标进行了定期观测,结果表明,物候期延迟了大约15天,青春品种萌动最早,为4月3日;枝条年平均生长量为24.3 cm,比原产地缩短约10 cm;花径平均大小为14.5 cm,比原产地短约5 cm;成花率平均为88.7%,其中玉狮子最高,平均为92.3%。不同品种紫斑牡丹在营口地区都能够良好地生长并开花,具有较高的观赏价值和广阔的发展前景。
Ten varieties of Paeonia rockii of 6 years old were introduced from Lanzhou of Gansu Province and plan- ted in Liaoning Agricultural College. Growth indexes, such as phenophase and growth increment of branch, were regularly observed. The results showed that the phenophase was postponed for about 15 days and Qinchun was the variety firstly germinated, in April 03. Annual average growth increment of branch was 24.3 cm and 10 cm shorter than that of the origin. Average diameter of flower was 14. 5 cm and 5 cm shorter than that of the origin. Average flower formation rate was 88.7 %. All varieties of P. rockii grew well in Yinkou region and flowered normally, with high ornamental value and broad prospects for development.
