Abstract Background Genus Fritillaria is one among the biggest genera of family Liliaceae comprising around 130–165 species. viewed as a significant genus and source pharmaceutically active compounds utilized in conventional drugs by folklore. worldwide medication food. Different chemically dynamic components separated from , their phytochemistry with structure pharmacology these have been exte...

The genus Hypericum is one of the most important medicinal plants that contain 17 species in Iran, three of them are endemics. This paper reports the essential oil composition of six Hypericum species from Iran. The essential oil analysis of a number of the studied plants has already been reported but their report from Iran may be valuable for scientists.  Samples collected between June and Aug...

Water stress is one of the main factors of severe damage and limitation of plant production in Iran. The paper reports a pot experiment conducted by using a factorial experiment based on a completely randomized design with three replications (each replication composed of four pots) to compare the physiological and biochemical characteristics of two varieties of tuberose (double- and single-flow...

Flower color variation among plant populations might reflect adaptation to local conditions such as the interacting animal community. In the northwest Iberian Peninsula, flower color of Gentiana lutea varies longitudinally among populations, ranging from orange to yellow. We explored whether flower color is locally adapted and the role of pollinators and seed predators as agents of selection by...

The tendency for flower longevity to increase with altitude is believed by many alpine ecologists to play an important role in compensating for low pollination rates at high altitudes due to cold and variable weather conditions. However, current studies documenting an altitudinal increase in flower longevity in the alpine habitat derive principally from studies on open-pollinated flowers where ...

The main topics are presented within standard framework Biological Flora Britain and Ireland: distribution, habitat, communities, responses to biotic factors, environment, structure physiology, phenology, floral seed characters, herbivores disease, history, conservation. is a pere...

The application of biofertilizers constitutes one of the main components of nutrient management with a fundamental role in sustainable agriculture and the improvement of plant qualitative traits. The present research assessed the effect of various treatments of phosphate solubilizing bacteria including Pantoea agglomerans strain P5 and Pseudomonas putida</...

in order to investigate the effects of soil texture and density on corm and flower yield of saffron (crocus sativus l.) an experiment was conducted as a factorial layout based on complete randomized block design with three replications at the faculty of agriculture, ferdowsi university of mashhad during two growing seasons of 2009-2010 and 2010-2011. treatment included 6 soil textures (clay loa...
