湿地松高产脂品系早期性状的研究

Study on the Characters of Pine Tree with High Content of Fat

为了选择适合建立脂材两用林或高产脂林的优良高产脂品系 ,对从美国引进的 16个湿地松高产脂品系的早期性状进行了综合分析评定。结果表明 :16个湿地松高产脂品系的树高、胸径、单株材积等生长指标及产脂量表现差异显著或极显著 ;在安徽省早期性状表现最好的品系是 2 0 4,表现较好的依次是 2 0 8、2 5 0、2 0 9、2 49、2 15、2 13、2 10、2 0

The character in the early growth period of pine trees with high content of fat introduced from USA, was comprehensively evaluated. The result showed that their growth index such as tree height, diameter, wood production per plant and yield were significant difference among 16 pine tree lines. The best one was pine line 204.
