摘要
四川百合资源丰富,种质资源的采集是百合保护利用的基础。针对岷江上游干旱河谷区进行了野生百合资源调查,并相继展开百合种质资源收集、保存及人工繁育等方面研究。该区内共发现岷江百合(Lilium regale Wilson)、川百合(Lilium davidii Duchartre)和宝兴百合(Lilium duchartrei Franch.)3种百合。其中岷江百合多生长于山坡灌丛下、向阳草坡或沟边、崖壁及岩石缝隙中,伴生植物多以豆科和蔷薇科居多;而川百合和宝兴百合多生长于林缘及高山灌丛、草丛间,伴生植物以蔷薇科、菊科植物居多。本文收集了3种百合的鳞茎和种子等种质资源,同时采取迁地保存鳞茎和低温保存种子的方式进行种质资源保存,并随之展开百合人工栽培繁殖试验,结果显示,百合最优的繁殖方式是鳞茎繁殖,其次是种子繁殖,再次是珠芽繁殖。
Sichuan Lily was rich in resources,and collection of germplasm resources was the basis for the protection and utilization of lilies. In this paper,the wild lily resources were investigated in the dry valley area of the upper reaches of the Minjiang River,and the collection,preservation and artificial breeding of lily germplasm resources were also researched in succession. A total of three lilies were found in the area: Lilium regale Wilson,L. davidii Duchartre and L. duchartrei Franch. Among them,L. regale grew mostly in hillside shrubs,on sunny slopes or in ditches,cliffs,and rock crevices,associated with leguminous and Rosaceae plants. L. davidii and L. duchartrei h mostly grew in forest margins,alpine shrubs and grasses,associated with Rosaceae and Compositae plants. Germplasm resources such as bulbs and seeds of three species of lilies were collected and preserved by ex-situ preservation of bulbs and cryopreservation of seeds,the artificial cultivation experiments of lilies were subsequently carried out. The results showed that the best breeding method for the lily was bulb propagation,followed by seed propagation and budding.
