In order to study the effects of different levels of nitrogen fertilizer and plant density on grain yield and its components in sunflower, an experiment was conducted using 'Record' cultivar at the Research Farm of College of Agriculture, Isfahan University of Technology in 1996. Four levels of nitrogen (0, 75, 150 and 225 kg/ha) and four plant densities (65000, 75000, 85000 and 95000 plants/ha...
Plant height, which shows dynamic development and heterosis, is a major trait affecting plant architecture and has an indirect influence on economic yield related to biological yield in cotton. In the present study, we carried out dynamic analysis for plant height and its heterosis by quantitative trait loci (QTL) mapping at multiple developmental stages using two recombinant inbred lines (RILs...
Due to the increasing need of the country to imported edible oil and rapeseed importance among oilseeds, efforts to increase its grain yield and oil content are of high importance. Therefore, recognizing the traits that increase grain yield of rapeseed has an important role in the success of breeding programs. Thus, sixteen rapeseed genotypes were evaluated in a randomized complete block design...
Aquilegia `Rose-White' flowered from seed in about five months without vernalization. GA4/7 treatment increased stem height, induced earlier flowering, and increased the number of flowers/ plant. Each of these responses, however, was dependent upon both rate (10, 25, or 50 ppm) and timing of application (4-, 8-, or 12-leaf stage). Treatment at the 4-leaf stage resulted in earlier flowering at a...
abstract in order to investigate the freezing tolerance of field grown fennel (fueniculum vulgare mill) under controlled conditions, a factorial experiment based on completely randomized design was conducted with three replications in agricultural college, ferdowsi university of mashhad in 2004. treatments were two fennel ecotypes (khorasan and kerman), two planting dates (oct 8th and 29th ) an...
to evaluate the effect of various levels of nitrogen fertilizer on nitrogen use efficiency and grain yield of canola cultivars, a split plot experiment based on randomized complete block design was conducted in 2007. factors were: nitrogen fertilizer at four levels (zero, 50, 100 and 150 kg/ha) in the main plots and canola cultivars at three levels (‘clover’, ‘opera’ and ‘okape’) in the sub plo...
abstract in order to evaluate the effects of drought stress and defoliation on sunflower, a study was conducted under controlled conditions. treatments were a combination of three levels of drought ((100, 60 and 30 percent of field capacity (fc)) and three levels of defoliation (control, removal of either 4 or 6 leaves from lower part of the plant) laid out, in a completely randomized design wi...
تأثیر پلیمرهای سوپرجاذب بر خصوصیات مورفولوژیک گیاه رزماری (Rosmarinus officinalis) در شرایط تنش خشکی
In order to study the effects of superabsorbent polymers and drought stress on some morphological characteristics of Rosmarinus officinalis, a pot experiment was conducted as factorial, based on completely randomized design with four replications, in which factors included four levels of drought stress (irrigation up to 100, 75, 50 and 25 percent of field capacity (FC) level, respectively) and ...
This experiment was conducted with the objective of evaluating the performance sage (Salvia officinalis L.) in different agroecology of Ethiopia for morpho-agronomic and chemical traits at Wondo genet, Hawassa, Qoqa and Holleta for two years from 2011/2012 to 2012/2013 cropping seasons. Data on plant height, branch number/plant, fresh leaf weight/plant, fresh stem weight/plant, above ground bio...
