Stay-green sorghum plants exhibit greener leaves and stems during the grain-filling period under water-limited conditions compared with their senescent counterparts, resulting in increased grain yield, grain mass, and lodging resistance. Stay-green has been mapped to a number of key chromosomal regions, including Stg1, Stg2, Stg3, and Stg4, but the functions of these individual quantitative tra...

to compare the yield and yield components of 10 promising dryland barley genotypes with a conventional cultivar (reihan03), a field experiment was conducted based on a randomized complete block design in miyaneh region in the 2010-2011 growing season, and their agronomic and morphological traits were recorded. genotypes were significantly different in terms of all the studied traits, and genoty...

abstract in order to investigate the effects of different irrigation regimes on yield and yield components of three chickpea cultivars, an experiment was conducted during the 2007 growing season at mashhad. six irrigation regimes including i1= full irrigation, i2= irrigation at branching, i3= irrigation at flowering, i4= irrigation at pod formation, i5= irrigation at seed filling stage, and i6=...

Stay-green (SG) is a term used to describe genotypes that have delayed leaf senescence as compared reference genotypes. SG could be favorable for grain yield, silage yield and quality, double exploitation (grain feed stover bioenergy), stress resistance, etc. However, some studies show contradictory results regarding the influence of or in uptake remobilization nutrients moisture grain. This ex...

this experiment was conducted to evaluate rate and duration of grain filling among old, modern and promising rice cultivars under different nitrogen levels in fields of  sari agricultural sciences and natural resources university, during 2008. two factors consisted of different urea fertilizer (0, 100 and 200 kg ha-1) as main plot and four promising lines (jelodar, partou, danesh and jahesh), 2...

During grain filling in barley (Hordeum vulgare L. cv. Barke) reserves are remobilized from vegetative organs. Glumes represent the vegetative tissues closest to grains, senesce late, and are involved in the conversion of assimilates. To analyse glume development and metabolism related to grain filling, parallel transcript and metabolite profiling in glumes and endosperm were performed, showing...

in order to study the effect of irrigation on fatty acid composition, oil and protein content of sunflower cultivars included azargol, allstar, alison and euroflor, an experiment was conducted at experimental field of the agricultural faculty of bu-ali sina university in 2007. treatments were arranged on split plot based on randomized complete block with three replications. the irrigation treat...

Occurrence of chalkiness is a major problem as it is an important parameter in determining the quality of rice grains. High temperature during the grain filling period results in loose packing starch granules that could be due to the involvement of starch degrading enzymes i.e., amylases. Therefore, two rice genotypes viz., PAU 3699-13-2-1-1 and PR122 were sown at two different dates. Thirty-da...

Two barley (Hordeum vulgare L.) forage varieties – Hemus and Karnobat, with high and low Rubisco content in the fully expanded first leaves (Metodiev and Demirevska-Kepova, 1992), were compared in pot vegetation experiments in respect of yield. Changes in the content of leaf pigments, the levels of total soluble and Rubisco immunoreactive protein were followed during six phenophases: 3rd leaf, ...
