- 摘要:
- 为促进观赏牡丹在宜昌地区的推广应用,以花王、岛锦、黑豹等40个观赏牡丹品种为试验材料,选取8个性状为评价因子,采用灰色关联度分析法,研究各性状指标对品种总体表现的影响,综合评价品种优劣。结果表明:参试的40个牡丹品种中,岛锦、香玉、彩绘等13个品种与参考品种的关联度较大(r≥0.700 0)具有较好的适应性和观赏性;紫二乔、如花似玉、日暮等13个品种与参考品种关联度一般(0.700 0>r≥0.650 0)适应性和观赏性一般;金晃、群芳殿、鲁菏红等14个品种与参考品种关联度较低(r<0.650 0),适应性和观赏性较差。评价结果与品种的实际表现基本一致,说明在观赏形状分值较合理的前提下,利用灰色关联度分析法对其进行性状综合评价是可行的。
- Abstract:
- In order to promote the popularization and application of ornamental peony in Yichang area,we used Huawang, Daojin,Heibao and other 40 varieties of Paeonia suffruticosa Andr. as experimental materials,eight characteristics were chosen as evaluation factors,by using the grey correlation analysis,the effects of varieties traits of Paeonia suffruticosa on the overall performance of the varieties were studied. The results showed that among the 40 varieties of Paeonia suffruticosa Andr.,there were 13 varieties of Paeonia suffruticosa such as Daojin, Xiangyu,Caihui had larger weight relation (r≥0.7000),showed a good adaptability and ornamental;13 varieties of Paeonia suffruticosa such as Zierqiao,Ruhuasiyu,Rimu had general weight relation (0.7000>r≥0.6500),adaptive and ornamental were general;14 varieties of Paeonia suffruticosa such as Jinhuang,Qunfangdian,Luhehong had low weight relation (r<0.6500),less adaptable and less ornamental. The evaluation results were consistent with the actual performance of the varieties. Using the grey correlation analysis method was scientific and feasible evaluation of Paeonia suffruticosa Andr..
