为筛选出木荷 Schima superba 优良种质应用于生产,满足精准提升森林质量的客观需求,有效
发挥森林固碳增汇的生态功能,于 2020 年在广东省东江林场对来自于广东省各地区 71 份 15 年生木荷优
树子代试验林的生长性状进行测定、评价和筛选。结果表明,木荷家系间的树高生长、胸径生长以及碳
储量具有较大差异, 15 年生木荷家系碳储量遗传力在 0.667~0.746 之间,选出碳储量增益较大的 109、 5、
84、 24、 28 等 5 个优良家系。 |

Abstract: |
In order to screen out the excellent germplasm of Schima superba to be used in production, and
meet the objective needs of accurately improving forest quality, and effectively improve the ecological function
of forest carbon sequestration and sink increase, we determined, evaluated and screened the growth traits of
71 15-year-old S. superba progeny test forests from various regions of guangdong province at dongjiang forest
farm in 2020. The results showed that there are quite significant differences in height, diameter at breast height,
and carbon storage between S.superba families, and the heritability of carbon storage of 15-year-old S. superba
families was between 0.667 and 0.746, and five excellent families including 109, 5, 84, 24, and 28 with larger
carbon storage gains were selected. |
