The most sensitive quantification of a DNA template relies on competitive PCR (9,10). This assay is based on competitive co-amplification of a specific target template sequence together with known amounts of a standard in the same test tube. The standard and the template being amplified using the same primers have to exhibit identical sequence at both ends. Moreover, to allow for a reliable qua...
In order to study the nectar quantity and quality of some onion cultivars and honeybees foraging activity on them, a complete randomized block design with three replications was conducted. Ten selected onion cultivars consisting of Ghom, Kashan, Azarshahr, Dorcheh, Tarom, Kazeroon 1, Kavar, Abarkooh, Hurand, and Yellow Sweet Spanish were used. Sixty mm mother bulbs of different onion cultivars ...
Background and purpose: Water and soil pollution with heavy metals are among serious ever-growing environmental problems. Human activity accounts for much of the poisonous metals and results in increases soil pollution. There are many factors related to soil and plants properties and environmental issues. Release of heavy metal into food chain in critical densities has harmful metabolic and phy...
For sustainable rice production in Iran the optimum use of production resources and the reduction of production costs are the two important issues. In this situation, water availability is a major limiting factor in sustainable rice production. Hence, changing of rice production system from lowland irrigated to aerobic production system, which is based on dry-seed sowing in non-puddled and non...
Arsenic (As) toxicity can be a hazardous threat to sustainable agriculture and human health. In order to investigate the effect of As (0, 25 and 50 µM) on growth, physiological traits and expression of As and Fe transporters in Tarom hashemi and Fajr rice cultivars, a factorial experiment based on a completely randomized design was conducted in 2020 in greenhouse conditions at Ayatollah Amoli B...
To compare the allelopathic potential of some Guilan province rice cultivars with allelopathically approved IRRI rice cultivars, a factorial experiment was conducted in completely randomized block design with 3 replications on the Experimental Farm of Agricultural College of Guilan University in spring 2005. Two factors including a) seven rice cultivars (traditional cultivars of Hashemi, Ali Ka...
The olive (Olea europaea L.) tree is one of the most characteristic tree crops from the Mediterranean basin that they are frequently subjected to prolonged drought periods. Olive tree is able to tolerate the low availability of water in the soil by means of morphoanatomical and physiological adaptations. This experiment was conducted based on completely randomized design with three replications...
thrity seven isolates of magnaporthe grisea collected from several host plants from family of poaceae namely digitaria singuinalis, setaria italica, and echinochloa sp.were tested for their pathogenecity against two susceptible rice cultivars. conidial suspensions were prepared by the surfaces of 14-day-old cultures being washed with sterile water and adjusting the final concentrations to appro...
Sorkheh Dizaj apatite - iron oxide deposit is located in southeast of Zanjan, within the Tarom subzone of Western Alborz - Azarbaijan structural zone. The oldest units in the area are Eocene trachyte, trachyandesite, olivine basalt and volcanoclastic brecciated tuff and lapilli tuff intruded by a quartz-monzonite, monzonite and granite subvolcanic pluton of Late Eocene - Early Oligocene age. Th...
