云南松不同种源试验林的产脂量研究

摘要

The resin yield of Pinus yunnanensis experimental forests distributed at Shuangbai Maidixin forest farm and Kunming arboretum were studied. The results indicated that the average resin yield and side gutter resin yield of Shuangbai Maidixin forest farm were higher than Kunming arboretum. Among all the tested provenances, the resin yield of four provenances namely Lushui, Ninglangxibuhe, Huaping and Yachang are relatively high, whereas nine provenances including Funingmuyang, Shuangbaibaishuihe, Luopingbadahe, Qujingsanbao, Yunxian, Lufeng, Yachang 550, Mile and Yanshan are relatively low. The resin yield performance of Pinus yunnanensis shows certain genetic stability.%通过对双柏麦地新林场及昆明树木园大马山32个种源的云南松产脂量的测定试验,结果表明,昆明大马山种源试验林中云南松平均产脂量与侧沟产脂量均低于双柏麦地新林场中云南松产脂量.产脂量高的同为泸水、宁浪西布河、华坪、雅长林场4个种源地云南松；产脂量低的同为富宁木央、双柏白水河、罗平八大河、曲靖三宝、云县、禄丰、雅长550、弥勒、砚山9个种源地云南松；云南松产脂量的高低具有一定的遗传稳定性.
