摘要/Abstract

摘要： 通过踏查和实地样方调查相结合的方法,对甘肃岷县野生当归资源进行全面普查,旨在揭示该生态区野生当归资源分布特点、药材储量及其与栽培当归的差异性。结果表明,首次在甘肃岷县寺沟乡马烨林场石台山、马坞乡繁荣村4社和马坞乡沙金村上十子等3处阔叶林样地及附近发现野生当归居群,均属于马烨、马沿林牧区,分布面积约为17.9 km²,药材储量约为1094.9 kg。野生当归除株高、根色和大小以及茎色等与栽培当归有一定的差异外,其他植物学特征与栽培当归基本一致。与栽培当归相比,野生当归植株的叶片数、株高、地上部鲜重、根粗、根鲜重和根干重等生长指标均显著低于栽培当归,分别为栽培当归的64.7%,64.5%,47.6%,28.6%,26.2%和38.1%。栽培当归中,麻口病的发病率为17.5%,其他病害发病率为5.0%,而野生当归中,未发现麻口病和其他病害。以上结果说明,尽管野生当归生产性能低于栽培当归,但野生当归具有较强的抗病性,是当归抗病新品种选育的宝贵基础材料,保护和发掘利用野生当归种质资源(尤其是道地产区的野生资源)显得至关重要。建议有关部门将岷县野生当归分布区域尽快加以保护。

Abstract: Using methods of route survey and sampling investigation, wild Angelica sinensis resources in Min County were comprehensive surveyed in order to further explore distributed characteristics of the resources, medicinal materials reserves, botanical feature for the wild plant in differently ecological districts of Min County, and to explore its differences in plant morphology and disease resistance with the cultivated A. sinensis. The results showed that the wild A. sinensis populations were found for the first time in three sample sites as Maye forest farm at Sigou Township, the 4th commune of Fanrong village at Mawu Township and Shangshizi Shajin village at Mawu Township and their neighborhood in Min County, Gansu province. The wild A. sinensis only distributed in the Maye and Mayan forestry area of Min County and the distribution area was nearly 17.9 km² with about 1094.9 kg of medicinal materials reserves. There existed no difference in most botanical features between the wild and the cultivars, except for plant height, root size, root color and stem color. Compared to the cultivated A. sinensis plants, morphological parameters of the wild A. sinensis plants were significantly lower (P＜0.01). Leaf number, plant height, the fresh weight of the above ground parts, root diameter, the fresh and the dry weight of root of the wild A. sinensis plants were 64.7%, 64.5%, 47.6%, 28.6%, 26.2% and 38.1% of the cultivated ones dug at the same time, respectively. Disease investigation result showed that incidences of Ditylenchus destructor and other disease were 17.5% and 5.0% respectively in the cultivated A. sinensis plants, but none was found in the wild A. sinensis plants. The above results showed that the wild A. sinensis was valuable basic-materials to breed new A. sinensis varieties with disease resistance, although its productive performance was lower than that of the cultivars. It considered that to explore and protect the wild A. sinensis resources (especially in genuine producing area) is extremely important to breed new varieties of A. sinensis in the future. So it suggests that the related agency should make policy to protect the wild resources found in Min County as soon as possible.
