湿地松种子园家系生长表现
|
摘要
为进一步开展湿地松优良家系培育试验,筛选速生、丰产等不同功能品系,为我国造纸业、建筑以及板材业提供优质原材料及优质生态产品;通过将美国引进的三代湿地松种子园半同胞家系和全同胞家系及本项目组自主培育的湿地松家系放在一起开展子代测定试验。参试的湿地松半同胞家系14个、全同胞家系8个。对其3年生测定林胸径和树高进行了测定分析与比较。结果表明:1)不同湿地松半同胞和全同胞家系间,在树高和胸径生长方面均存在显著差异;2)综合比较每个家系树高和胸径生长状况,通过Duncan法选出了生长性状优良的半同胞家系S4、S11、S13、S16、S25,以及全同胞家系S14、S23、S17。
In order to further develop Pinus elliotti superior families cultivation experiment,screen functional strains of fast growing,high yield and high yield lipids, and provide high quality raw materials of paper industry, construction and panel industry and high quality eco-products for China, The progeny tests of Pinus elliottii three generation seeds that including 13 half-sib family and 7 full-sib family seeds imported from the United States and the high quality family cultivated by authors of this article were carried out. The DHB and tree height of different P. elliottii families in 3-year-old were studied. The results show that: 1) There were signi?cant differences in DHB and tree height among P. elliottii half-sib family and full-sib family; 2) According to Duncan'contrast, S4, S11, S13, S16 and S25 were selected for the optimal half-sib family, and S14, S23 and S17 were selected for the optimal full-sib family.
