To investigate the potential of corn (Zea Mays) for cleaning of soils polluted by cadmium and the effect of different levels of sulfur (S) element on biomass and root and concentration of some micronutrients, a greenhouse experiment was performed in Zanjan University in 2008. In the completely randomized factorial design with three replications, three levels of elemental S (0, 1 and 2 ton ha-1...
Response of Iranian Rice Recombinant Inbred Lines (Oryza sativa L.) to Salt Stress in Seedling Stage
Study of the morphological genetic diversity of 114 lines, which have been derived from the crosses between Tarom Mahalli and Khazar cultivars, has been performed at seedling stage as completely randomized design at the normal condition and salinity stress of 8 dS.m-1 in a hydroponic system. Significant differences were detected between genotypes for all traits. Mean of comparison demonstrated ...
this study was conducted to investigate the effects of applying deficit irrigation on aboveground biomass, leaf area and root biomass for maize hybrid 704 single-cross. experimental treatments included 4 different irrigation levels, 5 growth stages with three replicates in a completely randomized factorial statistical design. aboveground biomass, leaf area and root biomass in 4 longitudinal sec...
To evaluate the effect of arbuscular mycorrhizal (AM) fungi (Glomus mosseae and Glomus intraradices) and Mesorhizobium Ciceri bacteria at three soil moisture levels [28% (field capacity, FC), 15% (-5 bar suction) and 9% (-10 bar tension) by weight] on morphological properties of root and aerial parts of chickpea, a greenhouse factorial experiment, arranged as a complete randomized design, was c...
in order to investigate the effect of root pruning in morphological and physiological characteristics of juniperus excelsa seedlings an experiment was carried out on transplanted one year-old seedlings. treatments included root pruning intensities (1-slight pruning (2-moderate pruning and 3- control (no root pruning)) .experiment design was completely randomized design. each treatment included ...
Due to the importance of Acer monspessulanum in Iranian mountain forests, a study was carried out to reliably estimate its woody biomass and growing volume via allometric equations. Four transects, five trees in each were chosen randomly. The characteristics of standing trees including: diameter at root collar, height, number of stems and crown width were measured, then trees were finally cut d...
The current research is based on the existing ecological conditions in the Zagros forests and knowledge of the response of forest trees to these conditions and the purpose of this study is to investigate the effect of topographic factors, tree characteristics on of fine roots biomass of gal oak (Quercus infectoria Oliv.) and also to compare the amount of nitrogen, phosphorus and potassium in th...
the history of plant’s used for mankind is as old as the start of humankind. initially, people used plants for their nutritional proposes but after the discovery of medicinal properties, this natural ?ora became a useful source of disease cure and health improvement across various human communities. berberis vulgaris is one of the medicinal plants used in iranian traditional medicine. berberis ...
In this study, two isolates of genus Microdochium (W2 and B26) was isolated from the roots of healthy barley plants in agricultural fields from Kermanshah province in 2014 and were identified as Microdochium bolleyi based on morphological and molecular characteristics. Dual culture studies revealed that W2 and B26 inhibit 45% and 20% of the radial growth of Ggt in tur...
abstract extract prepared from aerial part of pycnocycla spinosa is a relaxant of rat ileum contractions. the objective of this research was to study the spasmolytic activity of p. spinosa root extract for comparison with the aerial part extract. hydroalcoholic extracts were prepared by percolation method. a portion of rat ileum was removed and suspended under 1 g tension in tyrode’s solution...
