Investigation into semen characteristics of naturally-fertile pairs in vitro and their correlation with fertility in Florida Sandhill crane
Journal of Northeast Forestry University - Tập 9 - Trang 71-76 - 1998
Semen characteristics of naturally fertile pairs and their correlation with fertility of eggs in Florida sandhill crane (Grus canadensis pratensis) were examined. Six pairs were used in this experiment, and all of them that had bred before were housed in open individual pens. These pairs were isolated physically each other but not visually and audibly. Semen was collected twice (Tuesday morning an...... hiện toàn bộ
Spatial patterns nitrogen transfer models of ectomycorrhizal networks in a Mongolian scotch pine plantation
Journal of Northeast Forestry University - Tập 29 - Trang 339-346 - 2017
Ectomycorrhizal (EM) networks provide a variety of services to plants and ecosystems include nutrient uptake and transfer, seedling survival, internal cycling of nutrients, plant competition, and so on. To deeply their structure and function in ecosystems, we investigated the spatial patterns and nitrogen (N) transfer of EM networks using 15N labelling technique in a Mongolian scotch pine (Pinus s...... hiện toàn bộ
Point-cloud segmentation of individual trees in complex natural forest scenes based on a trunk-growth method
Journal of Northeast Forestry University - Tập 32 - Trang 2403-2414 - 2021
Forest resource management and ecological assessment have been recently supported by emerging technologies. Terrestrial laser scanning (TLS) is one that can be quickly and accurately used to obtain three-dimensional forest information, and create good representations of forest vertical structure. TLS data can be exploited for highly significant tasks, particularly the segmentation and information ...... hiện toàn bộ

A site dependent top height growth model for hybrid aspen
Journal of Northeast Forestry University - Tập 24 - Trang 691-698 - 2013
In this study height growth models for hybrid aspen were developed using three growth equations. The mean age of the hybrid aspen was 21 years (range 15–51 years) with a mean stand density of 946 stems ha−1 (87–2374) and a mean diameter at breast height (over bark) of 19.6 cm (8.5–40.8 cm). Site index was also examined in relation to soil type. Multiple samples were collected for three types of so...... hiện toàn bộ
Nutrients of green and senesced leaves of a Robinia pseudoacacia plantation along a latitudinal gradient on the Loess Plateau, China
Journal of Northeast Forestry University - Tập 32 - Trang 2499-2506 - 2021
Plantations have been widely established to improve ecosystem services and functioning. Black locust, Robinia pseudoacacia L. is a common, widely planted species to control soil erosion on the Loess Plateau. Previous studies have focused on economic values but the interactions between soil and plant carbon (C), nitrogen (N) and phosphorus (P) remain unknown. Investigating variations of soil, green...... hiện toàn bộ
Response of colour and hygroscopic properties of Scots pine wood to thermal treatment
Journal of Northeast Forestry University - Tập 24 - Trang 571-575 - 2013
The effect of heat treatment on the surface colour and hygroscopic properties of pine wood were investigated in this study. Boards of Scots pine wood (Pinus sylvestris L.) were subjected to thermal treatment at 200°C, for 4, 6, and 8 h. The change of equilibrium moisture content and density values of the specimens in order to facilitate the understanding of the treated material behavior. The colou...... hiện toàn bộ
Characterization of mean stem density, fibre length and lignin from two Acacia species and their hybrid
Journal of Northeast Forestry University - Tập 29 - Trang 549-555 - 2017
The objective of this study was to compare the wood properties related to wood pulp quality of two widely planted Acacia species viz. Acacia mangium Willd. and Acacia auriculiformis A. Cunn. Ex Benth. and their hybrid. Acid insoluble lignin content (Klason), mean stem density and fibre length differed considerably among the species and hybrids. A. mangium possessed a high percent of lignin content...... hiện toàn bộ
A floristic survey of the Hyrcanian forests in Northern Iran, using two lowland-mountain transects
Journal of Northeast Forestry University - Tập 26 - Trang 187-199 - 2015
We investigated the floristic composition of the Hyrcanian forests and the related forest-steppe ecotone in Northern Iran by using two long ecological transects, from lowland to upper mountain areas. The study was conducted during 2008 and 2009 and yielded the identification of 395 plant taxa belonging to 233 genera and 78 families. Dicots with 300 taxa were the richest groups of the flora, follow...... hiện toàn bộ
