摘要：利用4类松树杂种(火炬松×洪都拉斯加勒比松、火炬松×巴哈马加勒比松、湿地松×洪都拉斯加勒比松、湿地松×巴哈马加勒比松)在浙北7 a和6类松树杂种(火炬松×洪都拉斯加勒比松、火炬松×本种加勒比松、火炬松×巴哈马加勒比松、湿地松×洪都拉斯加勒比松、湿地松×本种加勒比松、湿地松×巴哈马加勒比松)在皖南9 a的树高、胸径和材积指标,研究了不同杂种在不同地点的生长表现。结果表明:不同杂种类型在不同地点的生长差异非常显著。在浙北余杭试验点火炬松×洪都拉斯加勒比松生长最好,其中材积增长超过对照40%的杂交组合有PTCH20、PTCH12、PTCH41、PTCH17、PTCH61和PTCH16共6个,全部是火炬松×洪都拉斯加勒比松,占该试验点所有杂交组合的11.11%;在皖南太湖试验点生长较好的杂交组合多为湿地松×古巴本种加勒比松,少量为湿地松×洪都拉斯加勒比松,同时该地区火炬松×洪都拉斯加勒比松杂种也有生长较好的杂交组合,该地区优良杂交组合(材积超过对照40%)包括PECC1-37、PECH12-9、PTCH13-24、PECC18-55、PECH42、PECC18-32、PECC10-6共7个,占所有杂交组合的28%,包括3个杂交组合类型(湿地松×本种加勒比松、火炬松×洪都拉斯加勒比松、湿地松×洪都拉斯加勒比松)。该结论和国内外关于杂种松的适应性及生长优势研究的结论基本一致,对我国南方不同地区发展速生杂种松具有参考意义。
Growth differences of four seven-year-old pine hybrids （ FFA × PCH, PTA × PCB, PEE × PCH, and PEE × PCB） in Northern Zhejiang and six nine-year-old pine hybrids （ PTA × PCH, PTA × PCC, PTA × PCB, PEE × PCH, PEE × PCC, and PEE × PCB ） in Southern Anhui were studied. The results revealed that there were significant differences in height, DBH and timber volume among these hibrids in different sites. Early selection indicated that PTA × PCH was the better hybrid type in mid-subtropical area of northern China （Test site ： Hangzhou City, Zhejiang; 30°27′N,119°48′E）, and PTCH20, PTCH12, PTCH41, PTCH17, PTCH61 and PTCH16 had good performance in stock volume among the PTA × PCH hybrids on this sites. While PEE x PCC（ Such as PECC1-37, PECC18-55, PECC18-32, PECC10-6） had better performance in stock volume in northern subtropical area of China （Test site： Taihu County, Anhui; 30°30′N, 116°12′E）. And some PEE × PCH, PTA × PCH hybrids （such as PECH12-9, PECH42, PTCH13-24） had good performance in northern subtropical, too. The stock volume of better hybrid progenies above exceeded the control （CK） by 40%. All the conclusion was consistent with the international research results about the adaption and heterosis of pine hybrids and could provide references in the selection of hybrid type in southern China.
