quinoa (chenepodium quinoa willd) is a grain-like crop which has a high production potential in iran. due to its seeds high nutritional value, it is compared with milk by the fao. in order to study the effects of temperatures on seed germination of quinoa seeds under salinity stress conditions, an experiment was conducted in seed lab of the university of tehran in karaj. temperatures regimes in...

this study was conducted to examine effects photothermal quotient on grain number of four wheat cultivars under four planting dates and four replications. the experiment conducted at the sabzevar agricultural sciences research during 2007-2008 and 2008-2009. various responses functions were evaluated to quantify the response of grain number to influencing parameters (environmental and non- envi...

partial rootzone drying (prd) is a new irrigation technique which improves water use efficiency without significant yield reduction in grape. to study the effects of partial rootzone drying and green pruning on yield and yield quality of thompson seedless grape a split plot experiment with randomized complete block design and three replications was conducted. the experiment was performed in tak...

abstract in order to study of relationship between timing and duration of phenological events and grain yield of wheat plants, an experiment was performed at moghan college of agriculture and natural resources-university of mohaghegh ardabili research farm during 2010-2011. the plant materials (81 wheat cultivars) were evaluated using a simple lattice design with two replications under irrigate...

The pattern of synthesis of nucleic acids and proteins in the development of the microspore and later during pollen germination and tube growth is discussed. In the pollen grain at the time of anthesis all the proteins that are required for germination and early tube growth are either already present, or if new proteins are synthesized, the messenger RNAs for their synthesis already exist in th...

• Lack of grain dormancy in cereal crops such as barley and wheat is a common problem affecting farming areas around the world, causing losses in yield and quality because of preharvest sprouting. Control of seed or grain dormancy has been investigated extensively using various approaches in different species, including Arabidopsis and cereals. However, the use of a monocot model plant such as ...
