| 摘 要： | 研究了南京地区黑松和马尾构间所产生的自然杂种。杂种可分三类：偏马尾松型、双亲中间及偏黑松类型，其中中间类型占多数，并从枝叶形态特征（包括幼苗和成年）；针叶比较解剖；球果种子性状；年生长节律；高、径生长，材积生长；木材容重；抗松材线虫以及核型等方面进行了自然杂种和双亲比较，证明该自然杂种具明显杂种优势，对该自然杂种的利用前景提出了看法。

| Abstract: | Some research was done of nalural hybridization between Pinus thunbergii Parl. and P. massoniana Lamb . around Naming. The natural hybrid consisted of three types: one type takes more after P. thunbergii ;another takes more after P. massoniana ; the other is mid type which takes up the majority. Hybrid vigor was tested through comparison between the natural hybrid and its Parents in the following rspects: Morphology of branch and needles; anatomy of needle; traits of cone and seed; annual growth rhythm; growth of diameter ,height and volume; wood gravity. Karyotype and Bursaphelnchais xylophilus resistence. The utilization potential of the natural hybrid was also discussed. |
