oregano (origanum vulgare l.), a native plant from iran, belongs to lamiaceae family. this species is traditionally utilized as sedative, diuretic, sweater and antiseptic, it is also used to treat of gastrointestinal diseases and constipation. origanum species are widely used in spice industry. in this study, the essential oil of the aerial parts of a subspecies from this plant namely origanum ...

partitioning of photoassimilates between the sinks is one of the most important physiological processes related to the yield of crops which are affected by drought stress. therefore, the effect of drought stress in flowering and grain filling stages, on the percentage partitioning of photoassimilates among different organs was studied in 14 rapeseed cultivars in a split plot experiment based on...

poa genus has a high value for grazing and forage conservation concerning thelivestock. in order to study the impacts of cold temperature and growing degree days(gdd) on seedling morphological trait and phonological development of two speciesinvolving poa pratensis and poa trivialis, this research was conducted in laboratory andgreenhouse and outdoor of research institute of forest and rangelan...

Early flowering is an important trait influencing grain yield and quality in wheat (Triticum aestivum L.) and barley (Hordeum vulgare L.) in short-season cropping regions. However, due to large and complex genomes of these species, direct identification of flowering genes and their molecular characterization remain challenging. Here, we used a bioinformatic approach to predict flowering-related...

Drought is one of the most important abiotic stresses that impair sesame (Sesamum indicum L.) productivity mainly when it occurs at flowering stage. However up to now, very few studies have attempted to investigate the molecular responses of sesame to drought stress. In this experiment, two genotypes having contrasting responses to drought (tolerant and sensitive) were submitted to progressive ...

Extensive studies on floral transition in model species have revealed a network of regulatory interactions between proteins that transduce and integrate developmental and environmental signals to promote or inhibit the transition to flowering. Previous studies indicated FLOWERING PROMOTING FACTOR 1 (FPF1) gene was involved in the promotion of flowering, but the molecular mechanism was still unc...

To study the impact of iron nanoparticles foliar application on mitigating the effects of drought stress on yield, yield components and  oil percentage of Goldasht spring safflower cultivar, an experiment was carried out in 2012 in the Agricultural Research Farm Station of Islamic Azad University, Roudehen branch as split plot in a completely randomized blocks design with three replications. In...

Background & Aim: Artemisia species with common Persian name of Dermaneh are found all over Iran and are used for treatment in infectious diseases such as malaria, hepatitis and other diseases. Some Artemisia species are used in traditionally as tonic and anti-helmintic in north of Iran. Artemisia haussknechtii is used in dyspepsia and other gastroint...
