摘　　要：通过对泰山竹林寺景区引种27年生的日本黑松和赤松精英树半同胞家系生长特性和遗传参数的研究发现:(1)黑松生长量略优于赤松,它们的平均胸径分别为21.83cm和20.84cm,平均材积分别为0.264m3和0.262 m3。从遗传特性上来看,黑松和赤松的胸径的家系h2分别为0.7668和0.4404。(2)从家系间比较可知:黑松大岛6#、黑松柳井3#、当地黑松、黑松柳井2#生长指标居于前4位,材积分别为0.4725m30、.3526 m30、.3179 m3和0.3144 m3。赤松都浓3#、赤松都浓2#、赤松大岛1#居于前列,材积分别为0.429 m3、0.343 m3和0.365 m3。Half--sib family growth characters and genetic parameters on 27--year old introducted Japanese black pine and Japanese red pine elites in Zhulin temple of Montain Tai were studied. The results obtained were as follows： （1） The Japanese black pine was little better than Japanese red pine in increment. The average DBH （diameter at breast height） of them were 21. 83cm and 20.84cm, while the average volume were 0. 264m^3 and 0. 262m^3 , respectively. The family h^2 on DBH of black pine and red pine were 0. 7668 and 0. 4404, which analysised from hereditary character. （2） The growth indexes of the black pine： Dadao 6^# , Liujing 3^# , local species, Liujing 2^# take the first four places, and their increment were 0. 4725 m^3 , 0. 3526 m^3 , 0. 3179 m^3 , 0. 3144 m^3 , respectively. The red pine.. Dounong 3^# , Dounong 2^#, Dadao 1^#were in the front rank, which increment were 0. 429 m^3 , 0. 343 m^3 , and 0. 365 m^3 , respectively.
