摘　　要：对福建省漳平五一国有林场2004年营建的马尾松种质资源库现存的716份种质的生长与花量性状进行调查分析。结果表明:马尾松种质资源9年生时树高、胸径和材积平均值分别为8.45 m、14.29 cm、0.0749 m^3,各生长性状差异明显,而10年生时雌、雄花量的变异幅度比生长性状更大;根据雌、雄花量情况将种质资源划分为均衡型、偏雌型、偏雄型、偏少型4种类型,其中均衡型种质较少,约占资源库的20%;根据种质资源库中各种质的不同类型、省区分类,利用多性状综合评价指数分别进行评价,将716份马尾松种质资源划分为优良、中等、一般、较差等4种类型,选出83份生长与花量性状均表现优良的种质资源。Investigation and analysis on the growth and flower yield of the 716 copies of germplasms in Pinus massoniana germplasm Bank which was built in 2004,and the results showed that the averaged height,DBH and volume were 8.45 m,14.29 cm,0.0749m^3.The growth traits were significantly different,and the variation range of male and female flowers was higher than that of growth traits.According to the amount of male and female flowers,the germplasm resources were divided into balanced type,partial female type,partial male type and few type.Balanced type germplasm was relatively low,accounting for about 20%.According to the germplasm resources of different characteristics and origin,and were evaluated by using the comprehensive evaluation index,the 716 copies of germplasm resources were divided into excellent,medium,general and poor,and selected 83 copies of germplasm resources in excellent group.
