摘要: 以国营荆门市彭场林场25年生湿地松针叶束水培无性系试验林为研究对象,通过生长量调查和树干解析,比较分析了 不同无性系之间及与实生林木之间的生长规律和差异,并对无性系的树高、胸径和材积性状进行了遗传参数估算。结果表明 :树高、胸径和材积在湿地松无性系之间均差异极显著,无性系内差异不显著;无性系平均树高、胸径、材积分别比实生林 木高9.1%、17.5%和50.8%,比速生丰产林标准值高34.0%、15.9%和74.7%;湿地松无性系主要经济性状中树高、胸径和材 积的重复力分别为0.44、0.85和0.85,遗传增益分别为418%、1466%和4318%。

Abstract: Twenty five years old, experimented stand of water culture clones propagated from needle fascicles of Pinus elliottii in Pengchang stateowned forest farm in Jingmen were studied. The growth regularity and differences within different clones were compared and the difference between water culture clones and seedling crops were also discussed. The genetic effects of clones in height,diameter at breast height(DBH) and volume were estimated and analysed. The results showed that there were extremely significant difference in height,DBH and volume within different clones and no significant difference among different individuals. The mean height ,DBH and volume of clones were about 9.1%,17.5% and 50.8% higher than seedling crops and about 34 0%,159% and 747% higher than standard of fast growing and high yield plantation. The repeatability of height,DBH and volume of clones were 044, 085 and 085 respectively. The genetic gain of height,DBH and volume of clones were 418%,1466% and 4318% respectively.
