摘要
为了解四川省胡颓子属(Eleagnus)植物资源概况,依据四川大学植物标本馆(SZ)2012份胡颓子属植物标本及中科院植物研究所植物标本馆(http://pe.ibcas.ac.cn/)该属4463份标本信息构建了四川省胡颓子属标本信息数据库,结果表明四川省有胡颓子属植物20种(包括2变种),其中四川胡颓子(E.davidii)、狭叶木半夏(E.angustata)和细枝木半夏(E.multifloravar.tenuipes)为四川省特有种;四川省广布种有牛奶子(E.umbellat)、披针叶胡颓子(E.lanceolate)和长叶胡颓子(E.bockii),运用最大熵模型(MaxEnt)预测了这三个广泛分布种的潜在分布区.运用层次分析(AHP)、Delphi调查法结合Yaahp 10.0软件,构建了胡颓子属植物良种选育体系,该评价体系由药用价值、绿化观赏价值、食用价值3个子系统和16个评价指标(药效、特有状况、分布范围、药用部位、开发现状、生活型、垂直分布、花期、花期长短、果期、果期长短、果实产量、经济性状、营养丰富度、功能、资源量)构成.评价结果表明,长叶胡颓子、角花胡颓子(E.gonyanthes)和披针叶胡颓子综合应用价值最高.利用绿化观赏子系统对四川省20种胡颓子属植物的绿化观赏价值进行评价,优先推荐角花胡颓子、长叶胡颓子和宜昌胡颓子(E.henryi)进行园林推广应用.
The Sichuan Eleagnus specimen database was constructed based on 2012 Elaeagnus plant specimens from Sichuan University Herbarium and Eleagnus information from Chinese Academy of Sciences（http：//pe.ibcas.ac.cn/）. The results showed that there were 20 species and 2 varieties, of which 3 species （E. davidii, E. angustata and E. multiflora var. tenuipes） are endemic to Sichuan. E. umbellate, E. lanceolate and E. bockii are widely distributed in Sichuan, and their potential distribution areas were predicted by MaxEnt. The breeding system was constructed by AHP, Delphi and Yaahp10.0,which had three subsystems（medicinal, green ornamental and edible value）and 16 evaluation index（efficacy, specificity, distribution, medicinal parts, development status, life type, vertical distribution, flowering period, flowering length, fruit duration, fruit length, fruit yield, economic traits, nutrient richness, function, resource）.The analysis results showed that E. bockii,E. gonyanthes and E. lanceolate had the highest comprehensive application value. At the same time, the green ornamental value of the 20 species of Eleagnus was evaluated based on the green ornamental subsystem, and the results indicated that E. gonyanthes, E. bockii and E. henryi could give priority garden application.
