【摘要】 为研究不同牡丹品种引种的适宜性,经初步筛选后选择6个名优牡丹品种胡红、景玉、洛阳红、太阳、乌龙捧盛、香玉进行物候、生长和开花性状研究,并进行引种适宜性综合评价。结果表明:引种牡丹品种的物候表现基本与原产地相当,适生性良好,能够正常地分蘖;各引进品种的花色保持与原产地一致,花径相当或略小,均能维持较高的观赏价值。进一步对引种适宜性进行综合评价,引进品种的适应性、生长势、植株形态、分枝性、着花密度等各项得分均在10分以上,且综合评分均较高(≥70分)。说明引进品种的适应性均较好,开花品质均较高,可从中筛选出引种适宜性综合评分较高的品种如乌龙捧盛、香玉、景玉等进行进一步的系统引种驯化研究。更多还原

【Abstract】 To study the suitability of different Paeonia varieties,after preliminary screening,6 famous varieties(Huhong,Jingyu,Luoyanghong,Taiyang,Wulongpengsheng and Xiangyu)were selected to research phenology,growth and flower chrematistics,together with the comprehensive evaluation of introduction suitability. The results showed that introduced varieties had similar phenology performance with the source area,also with good adaptability and normal tillering. Besides,introduced varieties maintain good ornamental values,with same flower colors and equal or slightly smaller flower diameter. Further comprehensive evaluation of introduction suitability including adaptability,growth potential,plant shape,branched and flower density of all introduced varieties were above 10 scores,with relatively high total scores(>70). This study illustrate that introduced varieties have high adaptability for introduction,those varieties with higher comprehensive scores(e.g. Wulongpengsheng,Jingyu and Xiangyu)could be better candidates for further synthesis studies for introduction.更多还原
