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 […]
Catalase and peroxidase enzyme activities in pulp wood tree seedlings under textile sludge applied sandy loam and clay loam soils
A pot culture experiment was carried out to study and compare the effect of terry towel textile sludge application on enzyme activity of fast growing pulp wood tree species raised under sandy loam and clay loam soils. The experiment was laid out in a Factorial Completely Randomized Block Design with two soil types viz., sandy […]
Biocontrol of Rhizoctonia solani causing stem canker disease of potato using rhizosphere mold fungi
The aim of the present work is to obtain effective rhizosphere fungal bio-control agents (bio-fungicides) that can antagonize Rhizoctonia solani; the fungal causal agent of stem canker disease of potato (Solanum tuberosum L.) and to improve the growth of the potato plant. A total of eleven different isolates of mold fungi were isolated from the […]
Genetic erosion: assessment of neglected and underutilized crop genotypes in South Western Kenya
The loss of Neglected and Underutilized Species (NUS) of crop results in reduction of the genetic base of the remaining varieties that may have a consequence upon changing environmental and ecological conditions. There is therefore, an urgent need to collect, document, characterize, conserve and utilize the traditional crops and formulate policies that will protect them […]
Repellency and toxicity of three plants leaves extraction against Oryzaephilus surinamensis L. and Tribolium astaneum Herbst.
Screening of plant extracts from wild species of plants for insecticidal properties could lead to the discovery of new agents for pest control. Keeping this in view, the ethanolic extracts of three plants leaves Neem (Azadirachta indica), Mint (Mentha longifolia) and Datura (Datura stramonium) were tested against two stored grain pests viz., Oryzaephilus surinamensis L. […]
Investigation of nursery treatments on sea buckthorn (Elaeagnus rhamnoides (L.) A. Nelson) seed germination in the field
This study was conducted for the first time in nursery treatment in order to pioneer forest trees of the species Elaeagnus rhamnoides and also to determine the effects of different treatments on seed germination in Iran. This species is resistance for plantation. Seeds originating from Qazvin province were placed in the nursery. Treatments comprised three […]
Fungal pathogens associated with grapevine wood lesions in Algeria
A field survey was conducted in Algeria to assess the state of dieback in some vineyards and identification the fungal pathogens associated with necrotic wood lesions. Field surveys conducted during spring seasons in 2006 and 2012 revealed that an average disease incidience was 25 % , the indice of disease severity varied of 0.5 – […]
Arsenic concentrations in commercial fish from freshwater and saltwater
Research was performed to investigate the concentration of arsenic in muscle and liver of fish species from freshwater, Barbus luteus, Aspius vorax, Cyprinion macrostomus in Karoon Rivers and saltwater, Liza dussumieri, Liza klunzingeri, Liza macrolepis, Scomberomorus commerson, Otolithes ruber, Scomberomorus guttatus, in Persian Gulf, Iran. Arsenic levels in muscles of seaport fish were high in […]
