The study of adaptability and results of medicinal plants cultivation in the conditions of Fars province collection
This research was aimed at studying economical and functional considerations, creating live gene bank of medicinal plants (collection) as well as investigation of collective cultivation and breeding of aborigine and exotic species for scientific and investigative considerations to be applied in educational, investigative, and administrative situations. It also was aimed at preventing the genetic extinction […]
Altitude and soil properties affected grassland and weed distribution
Altitude and soil properties can influence vegetation community and their density in rangelands. Knowing the relationships between plant species distribution with environmental factors would allow choosing the best strategy for the moderate of plants. The aim of this study was to investigate the correlation between plant species density with altitude and soil parameters in Khalatposhan […]
Floristic survey of weeds and rangeland plants in Khalatposhan station of Tabriz country
In order to ordination of weeds and rangeland plants, investigations were done in Khalatposhan rangeland of Tabriz county in 2013. Vegetation in each section was sampled by 176 plots (0.5 m × 0. 5 m) in grid method (20 m × 40 m). Data of presence and absence plants in different sections were analyzed through […]
Evaluation of agricultural crops biodiversity in Iran: a case study in Kermanshah province during 2003-2012
Plants and animals biodiversity affects the ecological functions of natural and agricultural systems. Therefore, reduction of biodiversity can be a serious threat for survival of ecological systems. Data were carefully provided from Ministry of Agriculture of Iran during 2003-2012. The results of diversity indexes indicated high biodiversity in Kermanshah province. They showed that a diversity […]
Food habit of hampala (Hampala macrolepidota Kuhl & Van Hasselt 1823) and its position in food web, food pyramid and population equilibrium of ranau lake, Indonesia
Hampala is an important economic fish species living in Ranau Lake. Food habit is closely related with trophic level in food web or food pyramid of fish population in the water. This study was aimed at knowing the position of food habit in food web, food pyramid, and population equilibrium in Ranau Lake. It was […]
Influence of the Chad-Cameroon pipeline on termite assemblages
The study of Chad-Cameroon pipeline disturbances on termite assemblages was conducted in 9 sites in the savannah and forest ecosystems, five years following the completion of the works. In each site an experimental design was made up of four transect belts, 100 m long by 2 m wide, two in the disturbed zone and two […]
Assessment of genetic diversity of iranian population of Anethum graveolens L. (dill) using AFLP molecular markers
Anethum graveolens L. (dill) is an important medicinal and industrial plant. The essential oil of this species is used in different industrial such as pharmacy, nutrition, perfume manufacturing and veterinary. The populations collected from different regions of the country were cultivated in order to investigate the genetic diversity of dill and were studied in aspect […]
Assessment of horticultural crops biodiversity in Kermanshah Province
Biodiversity is one of the important indices for assessment of agroecosystems sustainability. Unfortunately, the benefits of biodiversity are ignored in the agroecosystems. Therefore, the present study was conducted for evaluating horticultural crops biodiversity of Kermanshah province in the Campus of Agriculture and Natural Resources of Razi University during 2012. Data were collected by the Ministry […]
Phytoextraction of salts by indigenous weeds in arid land
Reclamation of saline soil is becoming one of the most requirements for boosting crop production and sustainable agriculture. This study was conducted to investigate the capacity of three indigenous weeds growing naturally in arid land on west of Saudi Arabia. Salts content and biomass production for each weed species was evaluated. Salts concentration at three […]
