effect of automobile pollution on the productivity of crocus sativus was studied for one year time period (october 2005-april 2006). the parameters which were analyzed viz total chlorophyll, carotenoids, leaf area, plant height, corm size, corm weight, corm yield, biomass, flower production, and length of stigma and style, showed a remarkable decrease as compared to control. total chlorophyll ,...
in this thesis, phosphorus ylides [phbppy], [no2bppy] and [brbppy] have been synthesized through the formation of phosphonium salt and dihydrogenation, followed by the reaction of pd(oac)2 and the orthopalladated dinuclear complexes [pd(?-cl)(phbppy)]2, [pd(?-cl)(no2bppy)]2 and [pd(?-cl)(brbppy)]2 have been produced. the reaction of dinuclear complexes and bidentate ligands [l = bipy (2,2-bipyr...
this research was conducted to examine the effect of a concurrent training on rest level of leptin of plasma and some hormonal factors in non-athlete subjects. the research population included non-athlete men who didn’t participate in any organized sport activities. 30 men were chosen voluntarily among the above-mentioned population and were divided into 2 groups: experimental (15 subjects) an...
Stem and peduncle bending by the weight of the flower is one of the main postharvest problems in gerbera (Gerbera jamesonii Bolus.) and sometimes caused stem crushing or water loss. In this research, silicon and salicylic acid were applied to enhance the mechanical strength of inflorescence stem, and the results revealed that stem curving was decreased by silicon and salicylic acid treatments. ...
Salvia reuterana Boiss of the Labiatae family is naturally distributed in many parts of Iran. Recent pharmacological studies have confirmed some medicinal properties of S. reuterana including antibacterial, carminative and anti-oxidant effects. In order to domestication of this valuable plant, morphological diversity were studied among seven S. reuterana population (Absard, Delichai, Shahmirzad...
Little is known of the dynamics of plant cell wall matrix polysaccharides in response to the impact of mechanical stress on plant organs. The capacity of the imposition of a mechanical stress (periodic brushing) to reduce the height of the inflorescence stem of Arabidopsis thaliana seedlings has been used to study the role of pectic arabinans in the mechanical properties and stress responsivene...
background and objectives: quinoa (chenopodium quinoa willd.) is a member of amaranthaceae family that originated in the andean region in bolivia, chile and peru five thousands of years and so it has a tiny and round seeds. quinoa in different combinations of food used as food, as well as how to cook like rice grains and known as the inca rice in the south american countries. the high nutrition...
To evaluate the allelopathic potential effects of giradol (Chrozophora tinctoria L.) organs on seed germination and seedling growth characteristics of watermelon (Citrullus lanatus L.), two experiments were carried out separately as a factorial in a complete randomized design with 4 replications; this study was carried out at Research Laboratory of Weed and Research Greenhouse of Faculty of Agr...
the structure and histogenesis of the stigma of datura stramonium was investigated by light and scanning electron microscopy to determine the developmental origin of the transmitting tissue and “wet stigma”. four developmental stages were defined on the basis of bud length. stage one, the histogenesis stage, was comprised of buds 2-15 mm in length. stage two, signified by the growth and develop...
plant spacing and nitrogen are the most important factors for increasing tuberose quality and quantity. in this study, field experiment carried out as factorial randomized completely block design (rcbd) in 3 replications. different levels of nitrogen (0, 50, 100, 150, 200, 250 kg/ha) of ammonium nitrate was used. second factor was different plant spaces (10, 15, 20 and 25 cm). results showed th...
