木荷1代种子园无性系生长及结实性状分析

Analysis on Growth and Fruit Characters of Schima superba from the First Generation Seed Orchard Clones

  • 摘要: 对福建华安县西陂国有林场4年生木荷无性系种子园进行生长和结实情况调查。结果表明:地径的变化幅度为783~1380cm,胸径的变化幅度为468~938cm,叉干数变化幅度为10~25个,枝下高的变化幅度为333~2990cm,树高的变化幅度为330~488m,冠幅的变化幅度为233~380m;2014年结实株率和2015年坐果株率无性系A4均最大,达7500%,分别是平均值的282、421倍;2014年结实株率为2727%,2015年坐果株率2091%;33个无性系中,2014年8182%的无性系有结实,2015年6061%的无性系有坐果,1818%的无性系2a均未坐果;2014年结实株率和2015年坐果株率呈极显著相关,相关系数083,木荷结实株率、坐果株率与胸径呈正相关,达到显著水平;无性系A4的综合评分最高,达33442。

     

    Abstract: Growth and fruit characters of 4a Schima superba clonal seed orchard in Xipi Stateowned Forest Farm, Hua′an County, Fujian Province were investigated. The results showed that ground diameter change range was 783-1380cm. The diameter change range was 468-938cm. The bifurcation number change range was 10-25. The clear bole height change range was 333-2990cm. The tree height change range was 330-488m. The crown width change range was 233-380m. The seed setting rate in 2014 and fruit setting rate in 2015 of A4 were the highest, up to 75%, they were 282 times and 421 times of the average, respectively. The seed setting rate was 2727% in 2014, fruit setting rate was 2091% in 2015. In 33 clones, 8182% of the clones had seed in 2014, 6061% had fruit in 2015, 1818% without fruiting in two years. The correlation between 2014 seed setting rate and 2015 fruit setting rate was extremely significant, whose correlation coefficient was 083. The seed setting rate and fruit setting rate were positively correlated with diameter, reached a significant level. The comprehensive score of A4 was the highest, up to 33442.
