摘要

秦巴山区有野生悬钩子38种12变种,是我国悬钩子属植物比较集中的分布区之一,对秦巴山区悬钩子种质资源的系统调查和综合分析结果表明:1.悬钩子类果实中维生素类(尤其是维生素E)和SOD等生物活性物质的含量异常高,蛋白质、氨基酸、有机酸和矿质元素含量不同程度地高于栽培水果,是一种急待开发利用的野生果树。2.黄果悬钩子、粉枝莓、华中悬钩子、弓茎悬钩子、喜阴悬钩子、插田泡、茅莓、山莓和高粱泡等具有直立生长、植株健壮、少刺或无刺、丰产、抗寒耐旱等经济性状,是悬钩子类果树选种和育种的优良种质材料,其中有些种类还可以直接引种栽培。3.悬钩子植物的美化环境和水土保持作用及药用保健价值也应受到重视。

Abstract

Thirty-eight species and 12 varieties of wild Rubus are present in Qinling-Bashan Mountain which is one of the main distribution area in China. By the survey and chemical analysis of Rubus resources, it shows that 1. Vitamins (particularly vitamin E) and SOD (superoxide dismutase) are very rich in fruits; contents of protein, amino-acids, organic acids and mineral elements are higher than that in apple, pear and citrus. 2. R. xanthocarpus, R. biflorus, R. cockburnianus, R. mesogaeus, R. coreanus,R. parvifolius, R. corchorifolius and R. lamberrtianus, with excellent characters of erect and stout habit, thornlessness, productivity. cold resistance or drough tolerance are thought to be the valuable germplasms for selecting and breeding, some of them can be cultivated. 3. It can also be recommended as useful resource for water and soil conservation and for medicinal plants.
