摘要
通过南阳楸树家系苗期对比试验,为楸树从家系的角度早期选择育种提供了依据。在南阳13县市区110株楸树优树资源调查基础上,收集并保存37株优树播种苗,进行有重复的完全随机区组育苗试验设计,通过对苗期生长量的测定,方差分析、差异性显著程度分析,结果表明:南阳楸树37个家系苗期地径和树高差异均达极显著水平,16,17,18,9,4个系号在苗期树高和地径生长是最快的。
The contrast test in seedling stage of Nanyang Catalpa Bungei C. A. Mey. Superior family,which based for selective breeding from the perspective of families.Investigation on 110 Catalpa Bungei C. A. Mey. superior trees in 13 counties in Nanyang province conserved and preserved 37 plus tree seedlings,blocks experimental design is randomized completely and repeatedly,according to growth in seedling stage,variance analysis and significant degree of difference analysis.Basal diameter and height of 37 families in seeding stage were highly significant,Four of No.16,17,18,9 grew the fastest.
