| 摘 要： | 通过对广西红锥5个种源32个优树子代的造林试验表明,在其幼树期(3年生)不同种源、家系的红锥林木生长差异显著,由此初步评选出4个种源及7个优良家系。此7个优良家系,与最差家系相比较,其平均树高增加12.60%~32.33%,平均胸径增加31.385%~38.72%,单株材积增加102.30%~235.77%。

| Abstract: | The planting comparison experiment was conducted on the germplasm of 32 quality tree individuals of 5 provenances of Castanopsis hystrix in Guangxi.The results showed that there are significant differences in young tree growth between different provenances and families,four provenances and 7 families with good quality were selected out.Compared with the family with the worst growing performance,the average tree height,DBH and individual volume of quality families increased by 12.60 %~32.33 %,31.385 %~38.72 % and 102.30 %~235.77 % respectively. |
