摘要: 筛选耐寒月季(Rosa chinensis Jacq.)资源对在寒冷地区增加绿化、提高观赏效果具有重要意义,试验对105份月季资源在自然越冬条件下进行了耐寒性调查。结果表明,供试月季资源总体成活率为64.74%,品种间耐寒指数分布在0.25~1.00,成活率为0~100%,跨度均比较大;100%成活的品种有15个,全部死亡的品种有7个。成活率与耐寒指数之间存在一定的相关性(R2=0.686 1);成活率越高,耐寒指数越分散。结合月季生长势、观赏性状等特性,最终筛选出20个适合在辽阳市绿化观赏应用的耐寒月季品种。

Abstract: It is very important to screen cold-resistant rose(Rosa chinensis Jacq.) resources, which is benefit for enhancing the ornamental effect and improving the greening in the cold area. In this study, the cold-resistant investigation of 105 rose cultivars is carried out under natural overwinter conditions. The result indicates that overall survival rate is 64.74%, cold resistance index in different cultivars spans from 0.25 to 1.00, while survival rate varies from 0 to 100%. 15 cultivars has 100% survival rate while 7 cultivars all die. There is a certain relation between survival rate and cold resistance index(R2=0.686 1). The variance of cold resistance index has a scattering tendency when survival rate increases. Combining with rose growth vigor, ornamental etc. 20 cold-resistant cultivars are screened out, which can be used for greening and ornamental in Liaoyang city.
