the aim of this study was to investigate the effect of irrigation period on the quality and quantity of yield and some morphological and physiological traits of three multigerm sugar beet genotypes named bp mashhad, bp karaj and 191. the experiment was in a split plot based on randomized complete block design , carried out at motahari research station of sugar beet seed research institute ...
We examined three different-ploidy wheat species to elucidate the development of aboveground architecture and its domesticated mechanism under environment-controlled field conditions. Architecture parameters including leaf, stem, spike and canopy morphology were measured together with biomass allocation, leaf net photosynthetic rate and instantaneous water use efficiency (WUE(i)). Canopy biomas...
in order to determine the effect of different levels of sulfur bentonite on yield and yield components of canola a factorial experiment was conducted on the basis of randomized complete block design with three replications in mashhad in 2009-2010 growing season. factors included four levels of sulfur bentonite (0, 300, 400 and 500 kg.h-1) and two varieties of canola (modena and zarfam). the res...
Remobilisation of non-structural carbohydrates (NSC) from leaves and stems and unloading into developing grains are essential for yield formation of rice. In present study, three recombinant inbred lines of rice, R91, R156 and R201 have been tested for source-flow-sink related attributes determining the nature of NSC accumulation and translocation at two nitrogen levels in the field. Compared t...
Background: Biostimulants are amino acids and organic components, which can play main role in the plant growth and dry matter accumulation. Objective: Determine the influence of foliar application of active amino acids on quality and quantity yield of Melissa officinalis L. Methods: This study was conducted in a research farm at the institute of medicinal plants on the base of randomized ...
Impacts of salinity become severe when the soil is deficient in oxygen. Oxygation (using aerated water for subsurface drip irrigation of crop) could minimize the impact of salinity on plants under oxygen-limiting soil environments. Pot experiments were conducted to evaluate the effects of oxygation (12% air volume/volume of water) on vegetable soybean (moderately salt tolerant) and cotton (salt...
Fungal diseases, especially leaf and stripe rusts are wheat yield reducing factors in Iran and the world. In this study, genetic diversity of 20 wheat varieties with different response to leaf and stripe rusts were studied using primers designed based on the conserved regions of plant disease resistance genes. The banding patterns of polymorphic markers were scored as dominant and number of amp...
in order to evaluate the effect of humic acid and zn on the grape yield and mineral concentration, a factorial experiment was conducted based on a randomized complete block design with three replications. the study was done on 20 years old grapevines in the farsan region from chaharmahal and bakhtiari province in 2013-2014. each of the factors, humic acid and zinc sulfate, were applied in three...
In order to evaluate the effect of potassium sulfate fertilizer and ascorbic acid application on yield and yield components and growth of quinoa (Chenopodium quinoa Willd.), a field experiment was carried out at 2018-2019 at Isfahan, central Iran. A factorial experiment based on a randomized complete block design with three replications was used. Experimental treatments were potassium sulfate i...
In complex task domains, such as games, students may exceed their teachers. Such tasks afford diverse means to tradeoff one type of performance for another, combining task elements in novel ways to yield method variations and strategy discoveries that, if mastered, might produce large or small leaps in performance. For the researcher interested in the development of extreme expertise in the wil...
