摘要：湿地松（Pinus elliottii Englem.）原产于美国,不仅是重要的用材、纸浆材树种,更是优良的产脂树种。我国在20世纪30年代初开始引进美国湿地松,目前种植面积达200万hm2,已经成为重要的用材、采脂树种[1-3]。松脂是生产松香、松节油的原料,也是重要的工业原料[4];然而,国内对松脂质量研究重视不够,研究方法较粗放[5-7],不能满足我国松脂产业发展对优质湿地松种植材料的需求。
To study the genetic variation of slash pine （Pinus elliottii） resin components, 98 individual trees from 38 open pollinated families in Changle Forest Farm, Zhejiang Province, were selected for the determination of resin components and the hereditary correlation analysis, the result shows that slash pine resin contains ten kinds of monoterpene, namely α-pinene, β-pinene, camphene, α-phellandrene, β-phellandrene, β-myrcene, sabinene, tficyclene, estragole and trans-anethole, which altogether account for more than 9. 86%. Analysis of variance indi- cates highly significant differences in all components except for estragole and tricyclene among the families （P 〈 0. 01 ） ; the estimated family heritability for monoterpene components is between 0.50 -0. 95 with strong hereditary transmission capability. There was a significant negative genetic correlation （ r = - 0. 46, P 〈 0. 01 ） between α-pi- nene and β-pinene. The resin acids mainly include twenty components in pimaric type acid and abietic type acid, namely： pimaric acid, palustric acid, sandaracopimaric acid, isopimaric acid, abieticacid, neoabietic acid, de- hydroabietate, communic acid, levopimarate, pimaral, isopimaral, 8,12-abietadienoate, 8,15-abietadienoate, 8, 13-abietadienoate, 7,13,15-abietatrienoate, 15-hydroxydehydroabietic acid, 8, 15-pimarene, rimuen, isosteviol and kaurene, among which the abietic type acids is greater than the pimaric type acid, analysis of variance indicates highly significant differences in pimaric acid, isopimaric acid, abietic acid, neoabietic acid, pimaral, isopimaral, 8,12-abietadienoate, 8,15-abietadienoate, 7,13,15-abietatrienoate, 15-hydroxydehydroabieticacid, 8,15-pimarene, and rimuen, the estimated family heritability for these twelve resin acid components is between 0.50 -0.81, the heritability is relatively stable.
