摘要
[目的]比较研究野生玫瑰(Rosa rugosa Thunb.)与栽培种重瓣红玫瑰(R.rugosa cv.′Plena′)染色体的核型。[方法]记述了吉林省珲春地区野生玫瑰的形态特征、分布状况、物候期及野生玫瑰果营养成分、变异类型,并对野生玫瑰与栽培种重瓣红玫瑰进行体细胞染色体比较分析。[结果]野生种为2n=14,栽培种为二倍体与多倍体的混杂体。[结论]该研究可以为育种工作者进行相关研究提供参考。
[Objective] The aim was to compare and study the karyotype between wild R.rugosa Thunb.and cultivars R.rugosa cv.′Plena′.[Method] The morphological characteristics,distribution,phenology of R.rugosa Thunb.in Hunchun of Jilin Province,and its fruits nutritional compositions and variation types were described.In addition,the karyotype between wild R.rugosa Thunb.and cultivars R.rugosa cv.′Plena′ was compared.[Result] The results showed that the wild R.rugosa Thunb.was 2n = 14 and the cultivars R.rugosa cv.′Plena′ was hybrid body formed by the diploid and polyploid.[Conclusion] The study provides a reference for plant breeder doing the relative study.
