摘要
通过对甘肃各主要林区、保护区野生果树种质资源的初步调查,研究表明:甘肃野生果树资源丰富,有312种和46变种(变型),隶属于32科、70属。这些野生果树主要集中在蔷薇科、虎耳草科、小檗科、猕猴桃科、葡萄科、胡颓子科。首次对甘肃不同地理分布区域野生果树资源的丰富性进行了研究,结果表明:甘肃野生果树在各地理区域间分布不均衡,陇南最丰富,陇东南、陇西南较丰富,河西走廊最贫乏,陇中和祁连山较贫乏。同时提出了开发利用策略。
Germplasm resource of wild fruit trees in main forestry regions and natured reserves of Gansu province were preliminarily investigated. The results showed that wild fruit trees resources were abundant in Gansu, where there were 312 species and 46 varieties （forms）, belonged to 32 families, 70 genera. Most wild fruit trees belong Rosaceae, Saxifragaceae, Berberidaceae, Actinidiaceae, Vitaceae or Elaeagnaceae. Wild fruit trees resources at different geographical distribution areas in Gansu were studied for the first time. The results showed that distribution of resources at various geographical areas were disproportion. Wild fruit trees resources were the richest in southern parts of Gansu, the resources were richer in southeastern and southwestern parts, the resources were the poorest at Hexi corridor, the resources were poorer at Qilian mountainous areas and middle parts. And some strategies for development and utilization of wild fruit trees resource were put forward.
