摘　　要：引进8个切花洋桔梗品种在贵阳地区进行栽培试验,通过设施栽培控制生长环境,观测不同品种间物候期、洋桔梗品种性状,对其进行主成分-聚类分析,研究洋桔梗在当地引种效果,筛选出贵州地区的适栽品种。结果表明,洋桔梗在贵州设施栽培条件下,能够正常生长发育。用主成分分析株高、茎粗、单株花数、叶对数、花径、瓶插天数指标,综合评价排序为优胜白色>惊艳绿色>蕾娜香槟>露西塔3粉色、露西塔2紫边>柯罗马浅紫改良>美人醉3红色。研究表明,优胜白色、惊艳绿色、蕾娜香槟适宜在贵阳地区引种栽培,其他品种也有各自的优点,在贵州引种时可适量选择,起到丰富市场的作用。In this paper,8 varieties of Eustoma grandiflorum for cut-flower were introduced to Guiyang area for cultivation experiments.The phenological period and characteristics of E.grandiflorum among different varieties were observed by controlling the growth environment of protected cultivation,and the local introduction effect of E.grandiflorum was also studied,which contributed to screening suitable varieties for cultivation in Guizhou.The results showed that E.grandiflorum could grow normally under the condition of protected culture in Guizhou.The comprehensive evaluation of plant height,stem diameter,number of flowers per plant,leaf logarithm,flower diameter and number of days in bottle by using principal component analysis was ranked as white Yousheng>green Jingyan>champagne Leina>pink Luxita 3>Luxita 2 with purple edge>light purple Keluoma>red Meirenzui 3.In conclusion,white Yousheng,green Jingyan and champagne Leina were suitable for the introduction and cultivation in Guiyang.Other varieties also had their own advantages,which could be selected appropriately when introduced in Guizhou to enrich the market.
