| 内容記述 | Primary production relations of plantations of Norway spruce, Picea abies, in the Tokyo University Forests in Hokkaido and in Titibu were studied and compared with the reports from Europe, its natural habitat. The relationship between height and age of many plantations of this species in Japan was summarized from literature and graphically presented. Height growth of this species in Japan was not different from the height in SCHWAPPACH's yield table. Four stands of different site quality in Hokkaido were compared. Mass of stem and branch, and total aboveground biomass of spruce per unit area were linearly proportional to site index expressed as the height at 45th year, but it was not for leaf mass. Most part of aboveground biomass of these stands was of spruce and undergrowth was minimum, though percentage of undergrowth biomass was higher on the poorest site. Production of stem per unit ground area was linearly proportional to site index, but production of branch and leaf was not. Thus aboveground net production per unit ground area was larger on better sites but not linearly proportional to the site index. Except for the poorest site, about nine tenth of aboveground net production was by spruce and the rest was by the undergrowth. Percentage of production by undergrowth in the poorest stand was larger. About one tenth of the aboveground net production by spruce was branch for all stands studied, but the percentages of stem and leaf were variable by stand. On the medium sites, the percentage of produced matter used for reproduction of leaf mass was largest. Net assimilation rate was largest on the medium sites and smallest on the poorest site, while efficiency of leaf to produce stem wood was highest on the best site. Discussions were given on this respect. Influence of dominance of trees within a stand on production relations was studied in a plantation in Hokkaido. Net production was largest in dominant trees, but there were not much differences in net assimilation rate and the efficiency of leaf to produce stem wood among tree classes. In the plantation in Titibu which is located on a remote site and not thinned for a long years, compared with the plantations in Hokkaido, leaf mass per unit ground area was larger and branch mass was smaller. Aboveground net production per unit area was somewhat larger while net assimilation rate and efficiency of leaf to produce stem wood was fairly lower, presumably because of larger leaf mass. Distribution of produced matter into branch was far smaller, reflecting severe competition in this stand. Leaf mass of these stands was compared with 34 stands in Europe. Leaf mass of 6 plantations of this species in Japan was larger than the mean of European plantations. Leaf mass of these plantation was also larger than forests of black spruce in Canada and Picea glehnii in Hokkaido. | |||||
