Differences in biochemical responses to cold stress in two contrasting varieties of rape seed (Brassica napus L.)
Forestry Studies in China - Tập 9 - Trang 142-146 - 2007
Changes in isozymes of peroxidase, catalase, superoxide dismutase, polyphenol oxidase, and esterase and activities of peroxidase and polyphenol oxidase in two annual Brassica varieties (AS-3 and CON, cold-tolerant and cold-sensitive, respectively) after 4°C treatment were assayed. After the low temperature treatment, PAGE patterns of isozymes of peroxidase, catalase, superoxide dismutase, polyphen......

Active organic carbon pool of coniferous and broad-leaved forest soils in the mountainous areas of Beijing
Forestry Studies in China - Tập 11 - Trang 225-230 - 2009
In order to explore the effects of different forest types on active soil carbon pool, the amounts and density of soil organic carbon (SOC) were studied at different soil horizons under typical coniferous and broad-leaved forests in the mountainous area of Beijing. The results showed that the amount of total SOC, readily oxidizable carbon and particulate organic carbon decreased with increasing dep......
A comparative study of mangrove floras in China and India
Forestry Studies in China - Tập 13 - Trang 173-182 - 2011
Species compositions in the mangrove habitats of China and India, especially on Hainan Island (China) and on the Sundarbans and the Andaman & Nicobar Islands (India), are of interest, showing several similarities and differences. The total mangrove areas of India cover about 6419 km2 with 43 species (23 major and 20 minor species), while the mangrove areas of China cover about 150 km2 with 26 spei......
Mapping spatial variation in acorn production from airborne hyperspectral imagery
Forestry Studies in China - Tập 12 - Trang 49-54 - 2010
Masting is a well-marked variation in yields of oak forests. In Japan, this phenomenon is also related to wildlife management and oak regeneration practices. This study demonstrates the capability of integrating remote sensing techniques into mapping spatial variation of acorn production. The hyperspectral images in 72 wavelengths (407–898 nm) were acquired over the study area ten times over a per......
The importance of an indigenous tree to southern African communities with specific relevance to its domestication and commercialization: a case of the marula tree
Forestry Studies in China - - 2011
Local communities in southern Africa derive many benefits from marula [Sclerocarya birrea (A. Rich.) Hochst. subsp. caffra (Sond.) Kokwaro]. These include the contribution of this species towards health, nutrition, food security and conservation by sharing local skills and knowledge related to it. Marula fruits can be eaten fresh, squeezed to make juice, brewed in traditional beer or used to make ......
Diversity of insect communities with different development phases in natural Populus euphratica forests in Xinjiang
Forestry Studies in China - Tập 10 - Trang 56-59 - 2008
An investigation method with sample plots was used to study insect communities in four different growth phases of natural Populus euphratica forests, which are juvenile, middle aged, over-mature and degraded forests, in Tarim, Xinjiang in July, 2005 and April, 2006. In our studies, 5,116 insect specimens, belonging to 12 orders, 61 families and 141 species, were collected. Lepidoptera and Coleopte......
Composition and characteristics of natural secondary forests in Shenzhen, South China

Productivity analysis in nature reserve: A case study in Hunan Province
Forestry Studies in China - - 2007
Although there are abundant natural resources in nature reserves, poverty is a common feature of the social economy in the communities surrounding nature reserves. Income from forestry is still the main source for residents living around nature reserves. The structure of inputs and outputs, i.e. productivity, in the forestry sector in nature reserves is quite different from one reserve to another.......
Land cover mapping of deciduous forest regions using ETM+ data: a case study of Azerbaijan Province, Iran
Forestry Studies in China - Tập 13 Số 4 - Trang 299-302 - 2011
Up to date information about the existing land cover patterns and changes in land cover over time is one of the prime prerequisites for the preparation of an integrated development plan and economic development program of a region. By using ETM+ image data from 2002, we provided a land cover map of deciduous forest regions in Azerbaijan Province, Iran. Initial qualitative evaluation of the data sh......
