elimination of potyviruses from two commercial iranian garlic populations, hamedan and azar-shahr, through thermotherapy and by meristem tip culture were investigated. the infected bulbs of either one of the populations were initially treated at 30o c for one week and then at 36oc for 5 weeks. the meristems of cloves at two sizes of 0.4-0.6 mm and 0.6-0.8 mm were then cultured on ms medium supp...
In this study, the chemical composition of the essential oils (EOs) extracted from aerial parts of native populations of Origanum vulgare ssp. vulgare from Iran was compared by GC and GC/MS. Plants were collected at bloom stage from their natural habitats located in Kaleybar, Sabalan, Meshkin Shahr and Chalus regions, respectively from East Azerbaijan, Ardabil, Ardabil and Mazandaran provinces....
Chickpea (Cicer arietinum L.) is one of the most important legume crops in Iran. Wilt disease caused by Fusarium oxysporum f. sp. ciceri, is the most important soil-borne disease of chickpea in the world. This disease caused high losses in different regions during recent years. Simple sequence repeat (SSR) were used to estimate genetic diversity in 114 of F. oxysporum isolates from six counties...
Extended Abstract Introduction: St. John’s wort is one of the most amazing and medicinal plants of interest worldwide, which is nowadays known as a certain cure for depression. However, the presence of dormancy and low seed germination is a barrier to the progress of its breeding programs. Despite the richness of the plant’s genetic resources, there are only a few studies reported on its propa...
to assess the effect of non chemical management of weed control on forage sorghum (sorghum bicolor) a field study was conducted in varamin, iran during 2010 crop year in a three- replicated- split factorial experiment laid out in randomized complete block design with four weeding levels (w1= one time cultivation at 3-leaf stage using a duck foot cultivator, w2= two times cultivation at 3 and 5-...
this study investigated the impact of explicit instruction of morphemic analysis and synthesis on the vocabulary development of the students. the participants were 90 junior high school students divided into two experimental groups and one control group. morphological awareness techniques (analysis/synthesis) and conventional techniques were used to teach vocabulary in the experimental groups a...
Rice is the staple food in Iran. Aroma is a character that has an important role in consumer’s preference and rice price. In this research, inheritance of aroma in F2 generation of crosses between aromatic Sang Tarom with Neda and Nemat non-fragrant varieties was investigated. In this study, along with phenotypic evaluation based on alkaline test from leaf samples, the genetic evaluation was co...
BACKGROUND Mediterranean visceral leishmaniasis (MVL) is an infectious disease that affects both human and animals. Domestic dogs (Canis familiaris) are principal reservoir hosts of MVL caused by Leishmania infantum. Dogs are definitive hosts for Neospora caninum and a risk factor for infecting intermediate hosts. The immunosuppression caused by visceral leishmaniasis (VL) can promote the occur...
The extended use of glyphosate resulted to its reduced efficacy against increasingly problematic weeds, such as Conyza spp. The objectives of this study were to determine the occurrence of glyphosate resistance in horseweed (C. canadensis) and fleabane (C. albida) populations in Greece, to evaluate the effect of weed growth stage on glyphosate efficacy under controlled environmental condit...
