introduction saffron as a food, spicy and medicinal plant has more than 62000 ha under cultivation with about 250 tons annual dry stigma production in iran, which includes about 90% of its world production. therefore, this plant has a specific value in agricultural export products of iran (fallahi et al., 2014). due to the important role of saffron in iran’s agroecosystems, the improvement of i...

Black gram plants subjected to varying levels of Zn supply (0.01 to 10 microM Zn) showed optimum growth and dry matter yield in plants receiving 1 microM Zn. The dry matter yield of plants decreased in plants receiving 0.01 and 0.1 microM Zn (deficient) and excess levels of Zn (2 and 10 microM Zn). The plants grown with Zn deficient supply showed delayed flowering, premature bud abscission, red...

to evaluate the effect of nano-iron chelate and also to make a comparison with effect of eddha iron chelate on saffron, an experiment was conducted as factorial based on a randomized complete block design with six treatments and three replications in shahed university, tehran in 2011 and 2012. treatments included iron fertilizer (nano chelate and common chelate) in three levels (zero, 450 and 9...

Background & Aim: Saffron (Crocus sativus L.) formerly was important in Turkey. Saffron cultivation has been decreased and it is now only cultivated in three villages in this country. It is triploid and exclusively propagated in a vegetative way by corms. In Turkey, saffron is traditionally planted by placing corms in rows randomly without grading or sorting; which results in placement...

in order to study the effect of sowing date and plant density on some quantitative traits and yield of sugar beet genotypes a field experiment was carried out at sugar beet seed production research station of karaj in 2006. treatments arranged in a split, split plot experiment based on completely randomized block design with four replications. the main factors were two sowing dates as 14 april ...

The success of plant reproduction depends on pollen-pistil interactions occurring at the stigma/style. These interactions vary depending on the stigma type: wet or dry. Tobacco (Nicotiana tabacum) represents a model of wet stigma, and its stigmas/styles express genes to accomplish the appropriate functions. For a large-scale study of gene expression during tobacco pistil development and prepara...
