摘　　要：本文通过自然抗性测定、人工接种和叶片结构解剖观察,比较了奥地利黑松和油松对赤枯病的抗性。结果表明,奥地利黑松在幼树期对赤枯病有较强的抗性,而当地树种油松则对赤枯病的抗性较差。这一结论为今后奥地利黑松在陕西的引种提供了一定的依据。Comparison of Pinus nigra var. Austria and Pinus tabulaeformis Carr. in terms of their resistance to blight was made through tests of their natural resistance, artificial inoculation of Pestalotia funernea （Desm）Stery. , and observation of anatomical structure of leaves. The results showed that Pinus nigra vat. Austria is more resistant to blight than Pinus tabulaeformis Cart. during young age period.
