摘要：为了给优质杉木资源的选择、培育和推广提供科学参考,以亚热带地区30年林分的183个杉木种源为研究对象,基于其生长量指标等基础数据,采用性状聚类分析法筛选出其中生长比较优良的地理种源和本地种源的木蕊,并进行年轮分析。结果表明:(1)筛选出生长比较优良的45个地理种源和2个本地种源。(2)通过对杉木不同生长发育阶段的方差F值进行比较可以得出,差异显著程度由大到小依次是中龄期、幼龄期、近熟期、成熟期。(3)结合年轮宽度均值比较分析4个年龄段现实增益,杉木幼龄阶段的增益明显小于后3个生长发育阶段的现实增益。在所列出的10个种源中,幼龄期的增益均值仅为9.64%,而中龄期、近熟期和成熟期的现实增益的均值则分别达到了65.59%、103.31%和96.30%。(4)比较4个年龄段年轮宽度均值,可合理地优选出后期速生型种源。其中福建三明、福建祟安、福建顺昌、福建建阳这4个产地的种源从幼龄期到成熟期属于全期速生型种源。广西融水四荣、湖南会同、贵州榕江、福建大田、福建永安5个产地的种源,在幼龄期增产能力表现优良,这5个种源和江西分宜与江西安福2个本地种源一样,都属于前期速生型种源。福建尤溪、贵州黎平、福建沙县、福建建瓯、广西三江、福建南平6个产地的种源,属于后期速生型种源。
The study of the selection on Chinese fir seed plays an essential part in practical production and daily life. This paper proposed to study selection and evaluation of different provenances in Chinese fir to provide a reference for selection, cultivation and extension of Chinese fir resources with superior quality. The 183 Chinese fir provenances of 30-year-old stands were the test object of Subtropical Forestry, which were selected as test material. To screen out the excellent samples from 45 geographic provenances and 2 local provenances, the research analysed the provenance difference of ring width between 45 geographic provenances and 2 local provenances in different age stages. During the four Growth stages： young stage, middle stage, near mature stage, mature stage, the radial growth of the different Chinese fir provenances was measured. Comparison of the variance F values of Chinese fir in different growth stages was carried out, and we listed provenances of the first 10 producing area with greater real gains in all stages.The results showed that the provenances of the 4 producing areas： Sanming Fujian, Suian Fujian, Shunchang Fujian, Jianyang Fujian,from young stage to mature stage,were the first 10 of 45 selected provenances in the gain that belonged the whole period fast-growing provenance.At young stage, the provenances of 5 producing area were Rongshui Sirong Guangxi,Huitong Hunan, Rongjiang Guizhou, Datian Fujian, Yongan Fujian, that the performance of gain capacity was excellent.And the provenances were the first 10 in the gain.From middle stage to mature stage, the capacity of gain declined outside the top 10.The 5 provenances that were the same with 2 local provenances： Fenyi Jiangxi, Anfu Jiangxi belonged to the early period fast-growing provenance. The provenance performance of 6 producing area： Youxi Fujian, Liping Guizhou, Shaxian Fujian, Jianou Fujian, Sanjiang Guangxi, Nanping Fujian,at young stage,was not prominent and the top 10. At middle stage, the capacity of gain was excellent,so,all of them belonged to the later period fast-growing provenance.
