Wheat is the main vital cereal crop in Mongolia (Triticum spp.) The size of seed one important feature quality. It directly related to plant growth, yield, market factor and harvest efficiency [1]. Equally are shape seed. middle spike ripens fast, after which upper lower parts ripen. Even though seeds part fill up at same time as section spike, later. Seeds have good filling bigger too. Moreove...

in order to investigate the integration of phosphorus fertilizer different levels and phosphorus solubilizing bacteria p.fluorescens on quantitative and qualitative forage yield of two fall barley cultivars, an experiment carried out at research farm of college of agriculture of university of tehran during 2009-2010. the experiment design consisted of three randomized complete blocks in a facto...

A series of seed priming experiments were conducted to test the effects of different pretreatment methods to seed germination, seedling growth, and seed yield traits in maize (Zea mays L.). Results indicated that the seeds primed by gibberellins (GA), NaCl, and polyethylene glycol (PEG) reagents showed a higher imbibitions rate compared to those primed with water. The final germination percenta...

in order to investigate the effects of polyethylene and organic mulches in different irrigation intervals on morphological characteristics and seed grain of sunflower (helianthus annus l.) hybrid azrgol, an experiment was conducted in split-plot design based on randomized complete blocks with three replications at research farm of college of aboureihan, university of tehran during year of 2009....

background and objectives: alkalinity stress caused by the alkaline salts such as na2co3 or nahco3 in the soil. alkaline stress affected germination, growth and crop productivity. moreover, the alkalinity stress can directly damage plant growth, alter the availability of nutrients, and disrupt the balance of ions and mineral nutrition. the application of different seed pretreatment methods is o...
