F2代湿加松和火炬松引种试验林早期生长分析

Primary Report on the Early Growth of Hybrid Pine (Pinus elliottii xP.caribaea) in Introduction Trial Plantation

引进湿加松、火炬松家系建立了引种试验林,并以本地马尾松做对照。4 a生调查结果表明:F_2代湿加松和火炬松生长速度明显优于本地马尾松,湿加松具有生长快、适应性强的特点,在闽北地区具有推广造林的潜力。

Some hybrid pine （Pinus elliottii vat. elliottii x P. caribaea var. hondurensis） and loblolly pine family seeds were introduced to establish trial stands and to find out their adaptability in Fujian. The results showed that hybrid pine and loblolly pine in four-year-old stand grew much better than the control of local masson pine. The rapid growth and good adaptability of the hybrid pine suggested its development potentiality in the northwest Fujian.
