the main purpose of this study was to determine the factors affecting the export of flowers in iran. after data collection using by the index of revealed comparative advantage (rca), the condition of business of flowers in iran was compared with a number of countries exporting the product. according to the results of study, the small elasticity of the exportation price in the function of export...

Bumblebees (Bombus spp.) and honeybees, Apis mellifera, both use odour cues deposited on flowers by previous visitors to improve their foraging efficiency. Short-lived repellent scents are used to avoid probing flowers that have recently been depleted of nectar and/or pollen, and longer-term attractant scents to indicate particularly rewarding flowers. Previous research has indicated that bumbl...

this study was carried out to investigate flower yield and yield components in iranian rosa damascena using 20 genotypes, collected from different regions of iran and grown in drylands and deserts research station of kashan, iran, using a randomized complete block design with three replications in 2007-2008. flower yield per plant, number of flowers per plant, plant height, leaf length, width, ...

Many co-sexual plants segregate female and male function among flowers on an inflorescence through dichogamy or the production of unisexual flowers. Sexual segregation may reduce self-pollination among flowers within inflorescences (geitonogamy), thereby increasing the pollen available for export to other plants. To assess these complementary roles we manipulated the simultaneously hermaphrodit...

Generally, the drilling mud is divided into three groups of oil (gas oil) and gas based on its base (the main phase), which is often mixed drilling mud from two or more times a mixture of all three fluids that are present at the same time. In this paper, we first investigate the types of drilling flowers, and then we study the pollution of the types of drilling flowers that...
