Abstract This research was conducted in Toroq Experimental field station, Mashhad, Iran, for two successive cropping seasons (2000-2002), using split plot experimental design based on complete randomized blocks with three replications. Moisture stress treatments (at seven levels) were assigned to main plots, including: D1 ( full irrigation), D2 (no irrigation from one-leaf to double ridge) st...
Application of selection index for screening desired plants based on complex quantitative traits can be more effective than direct selection. This study was conducted using an F2 rice population consisting of 87 plants derived from a cross between two cultivars Gharib and IR28. The purpose was to establish suitable selection indices for increasing yield and its related traits in research farm...

Plant diurnal oscillation is a 24-hour period based variation. The correlation between diurnal genes and biological pathways was widely revealed by microarray analysis in different species. Rice (Oryza sativa) is the major food staple for about half of the world's population. The rice flag leaf is essential in providing photosynthates to the grain filling. However, there is still no comprehensi...
to study the effects of below leaves excision and nitrogen application on stomatal characteristics of wheat flag leaf, grain protein, dry matter remobilization, grain yield and yield component, leaf area of winter wheat (t. aestivum cv. ghods) was artificially reduced under filed condition. the experimental design was a factorial on a rcb with 3 replications, a combination of three levels of de...
Extended Abstract Introduction and Objective: In order to investigate the effect of foliar application of main elements and micronutrients on morpho-physiological and yield traits of rice plants with the aim of increasing yield and reducing the use of chemical fertilizers, experiments in the cropping years 2015-2016 and 2016-2017 in the research farms of Nowshahr city (Mazandaran) was implemen...
In order to increase the quality of agricultural products and improve healthy food production systems, application of organic fertilizers has become very important in agroecosystems. To investigate the effect of different concentrations and time of humic acid foliar application on the qualitative characteristics and shoot and grain micronutrients content of Triticale, an experiment was conducte...
Previous studies with 95 bread wheat doubled haploid lines (DHLs) from the cross Chinese Spring (CS)xSQ1 trialled over 24 yearxtreatmentxlocations identified major yield quantitative trait loci (QTLs) in homoeologous locations on 7AL and 7BL, expressed mainly under stressed and non-stressed conditions, respectively. SQ1 and CS contributed alleles increasing yield on 7AL and 7BL, respectively. T...
in order to study the effect of different nitrogen fertilizer rates and source-sink limitation treatments on yield and yield component of contrast rice (oryza sativa l.) cultivars, a field experiment was carried out in the rice research institute of iran-deputy of mazandaran (amol) during 2006. a split split experiment in the basis of randomized complete block design with 3 replications and 3 f...
The water resource shortage in North China Plain is an increasing threat to the sustainabilityof wheat (Triticum aestivum L.) production. A two-year field experiment was conducted toexamine the effects of two supplemental irrigation (SI) methods on wheat flag leaf senescence,chlorophyll fluorescence and grain yield. The following field treatments were conducted:no irrigation (W0); SI with 60 mm...
