摘要
基于薰衣草新品种DUS测试的性状选择,对薰衣草(Lavandula angustifolia Mill.)的2个品种狭叶薰衣草(L.angustifolia)和甜薰衣草(L.intermedia)主要表型性状的差异性和相关性进行观测与分析。结果表明:狭叶薰衣草的植株形态优于甜薰衣草,且更能适应北方的引种环境。在花序部分,甜薰衣草的观赏性状总体上优于狭叶薰衣草,具有更丰富的花色变化。两个品种在主要的数量性状和质量性状上都表现出明显的差异性,并在生长过程中保持相对一致的稳定性。2个品种内各性状之间的相关系数都很高,狭叶薰衣草在1%显著水平上相关的性状配对个数略多于甜薰衣草。
In this study, based on the DUS testing of new Lavender varieties, the difference and correlation in phenotypic traits between Lavandula angustifolia and L. intermedia was investigated. The results showed that the plant morphological traits of L. angustifolia were better than that of L.intermedia, so L. angustifolia exhibited relatively high adaptive capacity to the environmental conditions in introduction area of north China. For the inflorescence, the ornamental traits of L.intermedia were better that of L.angustifolia, expecially in flower color diversity. The significant difference was found in both quantitative traits and qualitative traits between these two varieties, and these traits remian relatively stable in the growth process. The high correlation among various traits was found in these tow varietiies. The trait matching numbers at the 1% significance level in L. angustifolia were slightly more than that in L .intermediait.
