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。
The results showed that: (1) The growth of Pinus thunbergii was slightly better than that of Pinus sylvestris, their average DBH was 21.83cm and 20.84cm, with an average volume of 0.264m3 and 0.262m3, respectively. In terms of genetic characteristics, the pedigree h2 of DBH and Pinus thunbergii were 0.7668 and 0.4404, respectively. (2) According to the comparison among pedigrees, the growth indexes of Pinus thunbergii 6 #, Pinus thunbergii # 3, Pinus thunbergii and Pinus thunbergiiii 2 # are in the top 4, with the volume of 0.4725m30, .3526m30 and .3179 respectively m3 and 0.3144 m3. Pinus densiflora 3 #, Pinus sylvestris 2 #, Pinus sylvestris # 1 located in the forefront, with volumes of 0.429 m3, 0.333 m3 and 0.365 m3, respectively.
