切花月季岩棉苗性状评价及切花品质比较

Evaluation of cut rose rock wool seedling and comparison of cut flower quality

以8个切花月季品种的岩棉块苗为试材,研究不同品种育苗期、生长期、花蕾期、花期生长性状以及花期品质的差异,通过主成分分析法评价,筛选出适应本地环境条件的适宜品种。结果表明:岩棉苗不同时期各生长性状差异性显著,蜜桃雪山和白羊座栽培表现良好。对花期14个性状进行主成分分析,影响评价的主要因子为花量、花期、花茎和叶片,累计贡献率达到89.915%。综合4个时期生长性状和花期品质,观赏性和适应性状表现依次是蜜桃雪山、白羊座、桃红雪山、Pascal、弗洛伊德、香槟色、橙色和紫霞仙子。

Rock wool block seedlings of 8 cut rose varieties were used as test materials to study the differences of growth characters and quality of different varieties at seedling stage,growth stage,bud stage and flowering stage.The optimal varieties suitable for local environmental conditions were selected by principal component analysis.The results showed that there were significant differences in the growth characters of rock wool seedlings at different stages,and the cultivation performance of Peach Avalanche+and Rose Terrazza Aries was good.Principal component analysis showed that the main factors affecting the evaluation were flower amount,flowering period,flower stem and leaf,and the cumulative contribution rate was 89.915%.According to the growth characters and flowering quality of the four periods,the ornamental and adaptive characters were Peach Avalanche+,Rose Terrazza Aries,Pink Avalanche+,Pascal,Freud,champagnerose,Orange Forever and Nightingale.
