基于薰衣草属新品种DUS测试的性状选择,对狭叶薰衣草(Lavandula angustifolia)和甜薰衣草(L.heterophylla)主要表型性状的差异性和相关性进行了观测与分析。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。两种薰衣草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了相对一致的稳定性。两种薰衣草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。
Based on the selection of the traits of the new Lavender genus DUS, the differences and correlations of the major phenotypic traits of Lavandula angustifolia and L. heterophylla were observed and analyzed. The results showed that the plant morphology of lavender was better than that of sweet lavender and could adapt to the introductory environment in the north. In the inflorescence part, the ornamental characters of sweet lavender are generally better than the lavender of the narrow leaves, with a richer color change. Both lavender showed significant differences in the major quantitative traits and quality traits, and maintained a relatively consistent stability during growth. The correlation coefficient between the two lavender traits was very high, and the number of traits associated with narrow-leaf lavender at 1% significance level was slightly higher than that of sweet lavender.
