Abstract:
... Based on expert interviews and a structured survey with over 50 experts and industry leaders, this research provides a snapshot of forest carbon market development in Asia and offers future perspectives of challenges and opportunities. This study suggests that the carbon market is in the first generation of rigorous forest carbon standards programs. Those surveyed reflected a guardedly optimistic ...

Abstract:
... This study was conducted to examine the soil aggregate distributions and their relationship with microbial biomass carbon (C) concentration and soil C in Pinus rigida and Larix kaempferi plantations. Soil samples of 0–10 cm, 10–20 cm, and 20–30 cm depth were collected and the microbial biomass C concentration was measured. The soils were then classified into four aggregate size classes by wet-siev ...

Sterculia urens; dormancy; dormancy breaking; plant hormones; seed germination; seed treatment; seeds; storage temperature; trees; vigor; water content
Abstract:
... Sterculia urens is a commercially important tree with wide applications. Although it reproduces by seed, its germination requirements are not known. The seed also suffers with dormancy. The present study is an attempt to understand the proper storage conditions and also the type of dormancy in seeds of Sterculia urens . The optimum temperature for storage of seeds was found to be 0–4°C in a polyth ...

Abstract:
... Pericopsis elata is a timber tree with a high commercial value used as hardwood in the Congo basin forest. It is considered a threatened species by the International Union for Conservation of Nature (IUCN) and classified in 1992 in the annex II of the Convention on International Trade in Endangered Species of Wild Fauna and Flora (CITES). The natural regeneration of P. elata is problematic; an inc ...

Abstract:
... Salt-tolerant cell lines of Ailanthus altissima were selected from callus derived protoplasts. Murashige–Skoog (MS) liquid medium incorporated with various concentrations of NaCl was employed to enrich salt-tolerant A. altissima cell lines. Salt-resistant A. altissima cells were transferred on MS solid medium supplemented with 2.5 μM 2,4-dichlorophenoxy acetic acid (2,4-D), 0.5 μM benzyl adenine ( ...

Abstract:
... Individual tree growth models are important decision-making tools for forest management. We developed individual tree basal area growth models with Blue pine (Pinus wallichiana) data from Lete and Kunjo areas of Mustang district in Nepal. The sample trees were identified from all applicable ages, sizes, site qualities, and stand conditions and were cut. Diameters and ages were measured on the cut ...

Abstract:
... The minirhizotron technique was used to investigate the spatial (soil depth) and temporal (season) changes of fine roots (≤2 mm) in a mature Pinus densiflora forest. Length, production, and mortality of fine roots were measured at different depths on seven dates between March and October 2011. Average fine root length (mm cm ⁻²), production, and mortality (μm cm ⁻²) during the growing seasons were ...
