- 摘要:
- 以“巧克力纱”“银色卷轴”“教堂窗户”“李子布丁”“拼图”“红宝石”“海浪”“紫晶”“侃侃”“红卷毛”“天鹅绒”“黑暗之星”12个不同矾根品种为试材，采用形态生长指标和生理生化指标测定及方差和隶属函数值的分析方法，研究了弱光环境对不同彩叶矾根品种在贵州耐阴能力强弱的影响，以期为矾根在西南地区园林景观布置提供依据。结果表明：在弱光环境下，“李子布丁”“海浪”的幼苗生长前期表现出较强的耐阴特性；这些矾根品种耐阴能力大小依次为“天鹅绒”>“教堂窗户”>“李子布丁”>“银色卷轴”>“拼图”>“海浪”>“巧克力纱”>“红宝石”>“紫晶”>“侃侃”>“红卷毛”>“黑暗之星”。
- Abstract:
- Twelve Heuchera micrantha varieties (‘Chocolat Veil’‘Silver Scrolls’‘Cathedral Windows’‘Plum Pudding’‘Quilthers Joy’‘Montrose Ruby’‘Stormy Seas’‘Amethyst Mist’‘Can Can’‘Crimson Curl’‘Velvet Night’‘Dark Star’）were used as research materials.Morphological growth indexes，physiological/biochemical indexes，variance and subordinate function values were used as determination and analysis methods，to analyze the effect of leak light on Heuchera micrantha in Guizhou，and provided the evidence for arrangement of Heuchera micrantha in the southwest landscape.This study provided a scientific basis for the application of landscape architecture in Southwest China.The results showed that the seedling growth of ‘Plum Pudding’ and ‘Stormy Seas’ species showed stronger resistance to the weak light environment than others.The resistive ability of these Heuchera micrantha varieties were ‘Velvet Night’>‘Cathedral Windows’>‘Plum Pudding’>‘Silver Scrolls’>‘Quilthers Joy’>‘Chocolat Veil’>‘Montrose Ruby’>‘Amethyst Mist’>‘Can Can’>‘Crimson Curl’>‘Dark Star’.
