安徽苦苣苔科植物野生种质资源分布特征及其观赏性评价

根据标本、文献资料以及实地调查,安徽省野生苦苣苔科植物现已查明为8属13种.与《安徽植物志》(第四卷)记载的9属10种比较,取消了粗筒苣苔属Briggsia、唇柱苣苔属Chirita、小花苣苔属Chiritopsis和旋蒴苣苔属Boea,改添为报春苣苔属Primulina、羚角苣苔属Dorcoceras和丹氏苣苔属Damrongia,并增添了绢毛马铃苣苔Oreocharis sericea、大花石上莲O.maximowiczii和池州报春苣苔Primulina chizhouensis三种.通过本省该科植物的分布地区、生境及地形地貌的归纳分析,表明在气候、土壤及地形等环境因素的共同影响下,该科植物呈现出狭域且间断分布的特征.最后对本省该科植物的观赏特性进行了评价,并提出了合理保护和园艺开发利用的建议.

Distribution Characteristics and Ornamental Values of Wild Germplasm Resources of Gesneriaceae Plants in Anhui Province

According to specimen,document files and on-site investigation,there are 13 Gesneriaceae species belonging to 8 genera in Anhui Province.Compared to the 10 species,9 genera recorded in Flora of Anhui (volume 4),the Briggsia,Chirita,Chiritopsis and Boea were cancelled and replaced by Primulina,Dorcoceras and Damrongia instead,and three new species were added,i.e.Oreo charissericea,O.maximowiczii and Primulina chizhouensis.Based on the distribution,habitat and topography of Gesneriaceae plants in Anhui Province,influenced by climate,soil and topography,the Gesneriaceae plants showed stenochoric and sporadic distribution.The ornamental values of Gesneriaceae plants in Anhui province were evaluated;reasonable conservation strategy as well as horticultural exploitation patterns was proposed.
