樟树家系子代测定林试验的初步研究

Studies on Cinnamomum Camphora (L.)Presl Pedigree in Test Forest

通过樟树家系测定林的试验研究,结果表明92%的家系百日苗造林成活率达到76%以上,总体平均成活率达到90%。经方差分析,不同家系在树高、地径性状上差异极显著;樟树不同种源树高与经度呈极显著相关,与纬度呈显著相关;地径与经度、纬度均呈极显著相关;地径和树高呈显著相关;侧枝数与各生长性状及经纬度相关不紧密。根据种源育种值分析,建瓯和延平2个种源的生长性状优于总体平均水平,可作为建立种子园的优先选择对象。

Through the study of Cinnamomum camphora tree pedigree determination forest, it indicated that the survival rate of the 92% seedling afforestation planted hundred days achieved above 76%, and the ensemble average survival rate achieved 90%. It assumed the heredity was intensified, the tree height of the different seedling source with the longitude were extremely obviously related, obviously with the latitude related; the longitude, the latitude and the diameter were obviously related; The diameter and the tree height obviously were high related; The lateral branch number, each growth characters, the latitude and longitude related were not close. According to the breeding value analysis of provenances, Jianou and Yanping provenances＇ growth characters surpassed the ensemble average level, so the two provenances can be used as the priority selection object to establish the seed orchard.
