Relationships of tree height and diameter at breast height revisited: analyses of stem growth using 20-year data of an even-aged Chamaecyparis obtusa stand
Stem diameter at breast height (DBH) and tree height (H) are commonly used measures of tree growth. We examined patterns of height growth and diameter growth along a stem using a 20-year record of an even-aged hinoki cypress (Chamaecyparis obtusa (Siebold & Zucc.) Endl.) stand. In the region of the stem below the crown (except for the butt swell), diameter growth rates (ΔD) at different heights...
متن کاملCarbon balance of the aerial parts of a young hinoki cypress (Chamaecyparis obtusa) stand.
The aerial carbon balance of a 9-year-old hinoki cypress (Chamaecyparis obtusa (Sieb. et Zucc.) Endl.) stand with an aerial biomass of 24.6 Mg(DW) ha(-1) was studied over a 1-year period. Various components that constitute gross production were measured on the basis of the summation method. Respiration of the aerial parts of six sample trees was measured at monthly intervals by an enclosed stan...
متن کاملStand Diameter Distribution Modelling and Prediction Based on Richards Function
The objective of this study was to introduce application of the Richards equation on modelling and prediction of stand diameter distribution. The long-term repeated measurement data sets, consisted of 309 diameter frequency distributions from Chinese fir (Cunninghamia lanceolata) plantations in the southern China, were used. Also, 150 stands were used as fitting data, the other 159 stands were ...
متن کاملSomatic Embryogenesis and Efficient Plant Regeneration in Japanese Cypresses
There are six species in the genus Chamaecyparis worldwide, of which two, namely the Hinoki cypress (Chamaecyparis obtusa Sieb. et Zucc.) and Sawara cypress (Chamaecyparis pisifera Sieb. et Zucc.) are distributed in Japan (Maruyama et al., 2002). The Hinoki cypress is one of the most important commercial timber trees in Japan, representing about 25% of the plantation area in the country. Howeve...
متن کاملOptimal Solution in a Constrained Distribution System
We develop a method to obtain an optimal solution for a constrained distribution system with several items and multi-retailers. The objective is to determine the procurement frequency as well as the joint shipment interval for each retailer in order to minimize the total costs. The proposed method is applicable to both nested and non-nested policies and ends up with an optimal solution. To solv...
