摘要
对日本落叶松原生种源和家系选择及遗传资源保存林研究结果表明:13个优良种源和家系比4个对照平均值材积提高30.4%;4个优良种源比3个对照平均值材积提高27.4%;9个优良家系比对照材积提高35.8%,保存林7个优良材积比3个对照平均值材积提高44.3%。
The result from the study on original provenance and family selection and genetic resource conservative forest for Larix kaempferi (Lamb.) carr. showed that 13 elite provenances and families raised 30.4% than average value volume of 4 contrastss 4 elite provenances raised 27.4% than average value volume of 3 contrastss 9 elite families raised 35.8% than the contrast volume and 7 elite materials from the conservative forest raised 44.3% than 3 average value volume of the contrast.
