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
Wang-hao Zou, Yu-zhen Chen, Cun-fu Lu
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... hiện toàn bộ
Active organic carbon pool of coniferous and broad-leaved forest soils in the mountainous areas of BeijingForestry Studies in China - Tập 11 - Trang 225-230 - 2009
Yu-qing Geng, Xin-xiao Yu, Yong-jie Yue, Jin-hai Li, Guo-zhen Zhang
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... hiện toàn bộ
A comparative study of mangrove floras in China and IndiaForestry Studies in China - Tập 13 - Trang 173-182 - 2011
Yi-feng Yao, Subir Bera, Kumudranjan Naskar, Wen-bo Liao, Cheng-sen Li
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

Mapping spatial variation in acorn production from airborne hyperspectral imageryForestry Studies in China - Tập 12 - Trang 49-54 - 2010
Zhong Yao, Kenshi Sakai
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... hiện toàn bộ
Diversity of insect communities with different development phases in natural Populus euphratica forests in XinjiangForestry Studies in China - Tập 10 - Trang 56-59 - 2008
Hai-li Qiao, You-qing Luo, Cheng-ming Tian, Jian-hua Sun, Xiao-feng Feng
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... hiện toàn bộ
Productivity analysis in nature reserve: A case study in Hunan ProvinceForestry Studies in China - - 2007
Lan-hui Wang, Shu-rong Tian
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.... hiện toàn bộ
Land cover mapping of deciduous forest regions using ETM+ data: a case study of Azerbaijan Province, IranForestry Studies in China - Tập 13 Số 4 - Trang 299-302 - 2011
Hashemi, Seyed Armin, Fallahchai, Mir Mozaffar
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... hiện toàn bộ
