- 摘要:
- 以引进的“紫晶”“侃侃”“红卷毛”“天鹅绒”“黑暗之星”5个彩叶矾根品种为试材，分别研究了5个品种矾根在贵州冬季寡日照环境下苗期叶长、叶宽、叶片数等生长性状的差异性，以期为西南地区彩叶矾根品种的引种、筛选、驯化提供形态生长适应性上的参考依据。结果表明：5个彩叶矾根品种苗期叶长、叶宽总体上都呈上升趋势，在贵州适应性良好，并且“紫晶”品种在形态指标上均与其它4个品种之间存在差异性，其中第3生长阶段株幅、叶面积分别达到了20.6 cm和9.2 cm2的最大值。
- Abstract:
- Taking Heuchera micrantha varieties of ‘Amethyst Mist’‘Can Can’‘Crimson Curl’‘Velvet Night’‘Dark Star’ as experimental materials，the purpose of the study was to provide the basis for variety introduction，screen，acclimation in southweast China，the growth characteristics differences of leaf length，width and number of different Heuchera micrantha varieties on low-light winter in Guizhou were investigated.The results showed that the five Heuchera micrantha varieties showed an up trend of leaf length and width on seedling stage and exhibited the favorable adaptability in Guizhou Province.Moreover，there were significant differences in form indicators between Heuchera micrantha varieties (‘Amethyst Mist’)and other four Heuchera micrantha varieties.Where in the third stage of growth reached the maximum canopy and leaf-area of 20.6 cm and 9.2 cm2.
