【摘要】 在大小兴安岭和呼伦贝尔草原樟子松自然分布区和黑龙江省重点引种区共10个林区,调查了樟子松形态变异。设置标准地92块,调查立木7363株,优树179株,做树干解析46株,建立子代林17hm~2,测定家系217个,树龄8～13年生。侧重研究了樟子松树皮形态变异及其与树干材积生长量、形质之间的关系。主要结论:(1)樟子松按树皮颜色和裂片形状,明显区分为黄皮型、褐皮型、红皮型和黑皮型4个类型,其中褐皮型株率占90%以上,是樟子松林的建群类型;(2)黄皮型是速生优质类型,其树干材积比褐皮型大18%～45%,形数比其它3个类型平均值大2.7%,树皮率小3.3%,单株去皮材积大8%,(3)黄皮型的速生、树干圆满、树皮薄等性状是能遗传的。在8～11年生子代林中,黄皮型树干材积比褐皮型大35%。更多还原

【Abstract】 In Xinganlin Moutains,Hulunbeir Steppe of Heilongjiang province, 7363 stumpages and 179 plus trees of Pinus sylvestris var.mongolica were investigated in 10 forests of its native range and introduction areas, by setting 92 sample plots,stem analysis of 46 stands.217 families have also been tested in 17 hm~2 progeny trial plantation for 8～13 years.The relationships among the bark mophological variation,the volume increament and the form property of tree were paticularly studied.The main conclusions are:(1) The pine could be divided into 4 types:yellow bark,brown bark,red bark and black bark,according to their bark colour and lobe shape,among them,the percentage of brown bark is above 90%.(2 )The yellow type is fasti-growing type with high quality,its stem volume is 18%～45%more than the brown one and its form factor is 2.7%more than the mean of the other 3 types,but the bark rate is 3.3%less and the individual volume debarked is 6%more than others. (3) The characters of the yellow,such as fast growing,thin bark and full stem,could be heritable.In progeny testing plantation,the stem volume of the yellow bark type is 35%more than that of the brown.更多还原
