摘　　要：根据来自粤北、粤东、粤中、珠江三角洲和潮汕沿海地区的黎蒴半同胞家系子代测定林4年生和5年生树高、胸径等生长性状,分析比较以上5个局部种源的生长差异。方差分析结果表明,4年生时河源东江林场测定林的胸径和梅州梅南林场测定林的树高、胸径和单株材积在种源间存在显著差异;5年生时仅梅州试点的胸径和单株材积在种源间存在较显著差异。分地点对参试种源进行评定和选择,结果表明粤东种源在两个地点的早期生长较快且表现稳定,而粤中种源在河源试点也表现良好,通过种源早期选择获得的树高、胸径和单株材积的增益分别为1.30%~2.28%、2.70%~3.57%和5.45%~8.35%,对广东省黎蒴局部种源的早期生长作出了初步的比较与评价。To select adaptive provenances of Castanopsis fissa for Guangdong province,a total of 5 local provenances were collected and planted in Dongjiang Forest Farm and Meinan Forest Farm for progeny test.Three major growth traits were investigated to accomplish a preliminary comparison and evaluation of the early growth status of C.fissa.Four-year-old trees displayed significant differences in diameter-at-breast-height on Dongjiang Forest Farm and in height,DBH and individual volume on Meinan Forest Farm.Five-year-old trees only showed a little dramatic variations in DBH and individual volume on Meinan Forest Farm.An evaluation based on testing sites revealed that provenances from the east of Guangdong displayed well adaptability in both Heyuan and Meizhou testing sites,whereas those from the middle of Guangdong were also adapted to Heyuan testing site.The respective gains of height,DBH and individual volume were 1.30% ～2.28%,2.70%～3.57%,and 5.45%～8.35%.The results laid foundation for a preliminary comparison and evaluation of the early growth status of C.fissa.
