Five gradient concentrations (0.02, 0.04, 0.06, 0.08, and 0.10 g/mL) of leaching liquors from the roots, stems, and leaves of the invasive plant Bidens frondosa were used as conditioning fluid to examine its influence on seed germination conditions of the native plant Geum japonicum var. chinense in Huangshan. All leaching liquors of organs suppressed the seed germination of Geum japonicum var....
بررسی ارزش غذایی تاغ و عمل آوری آن با سود و آهک در مراحل مختلف رشدبا استفاده از روش کیسه های نایلونی
abstract this study is carried out to determine the chemical composition in the three vegetative stages of the haloxylon sp., degradation parameters, with adding naoh and ca(oh2 ). for this purpose, in may and october and january 2010 enough some haloxylon sp. of the ammary area was prepared. crude protein and ash percentage are decrease, neutral detergent fiber percentage with pragress stage ...
In order to study the salt tolerance of three species, Coreopsis grandiflora, Celosia cristata and Matthiola incana in germination stage, an experiment was carried out based on a completely randomized design with three replications in Hormozgan University laboratory in 2015. Salinity levels, including 3, 6, 9, and 12 dS/m were applied by dilution seawater and distilled water used as a control. ...
Ferula ovina is one of forage species of Isfahan and Chaharmahal va Bakhtiari whose natural spreads are under destruction. Finding information about its seed dormancy, effective factors in the dormancy breaking and also about optimal conditions of seed germination is necessary for recovery of this plant spreads. To actieve that goal, two factorial experiments were performed in completely random...
To evaluate the interaction of Cd and SA on seed germination of Safflower (Carthamus tinctorius L. cv. Soffe), this experiment was carried out as a factorial based on CRD with four replications in 2012, in Yasouj University seed lab. Factors included of four levels of seed priming with SA (0, 0.3, 0.6, and 0.9 mM) and eight levels of cadmium nitrate (0, 5, 10, 15, 20, 25, 30 and 35 mM). In all ...
In this study, we investigated the genetic basis of seed shattering and dormancy in Hokuriku 193 and bred an NIL improved these traits. Analysis of an F3 population from Hokuriku 193 × Koshihikari revealed a general correspondence between seed shattering and genotypes at the qSH1 locus, suggesting a strong influence of this locus on the seed shattering in Hokuriku 193. An F2 population from [ms...
To evaluate the effect of on-farm seed priming and methods of zinc sulfate application on some growth indices of two corn cultivars, an experiment was conducted as factorial in a randomized complete block design with three replications at the Research Farm of Bu-Ali Sina University, Hamedan, Iran. First factor was method of zinc sulfate application containing four levels of no-application, broa...
The effect of exogenous abscisic acid (ABA) on the rate of sucrose uptake by soybean (Glycine max L. Merr.) embryos was evaluated in an in vitro system. In addition, the concentrations of endogenous ABA in seeds of three soybean Plant Introduction (PI) lines, differing in seed size, were commpared to their seed growth rates. ABA (10(-7) molar) stimulated in vitro sucrose uptake in soybean (cv ;...
This study was performed to investigate the effect of storage conditions on seed germination performance of faba bean (cv. Shami). For this purpose, a three factors factorial experiment was conducted in laboratory of Seed Science and Technology, Faculty of Agriculture, Yasouj University, in 2013-2014, based on CRD design with five replications. The experimental factors were storage temperature...
Evaluating the merits of the wheat seed is an important significance for wheat breeding. We studied analytic hierarchy process (AHP) for seeds grading by digital image processing techniques in the paper. Firstly, preprocess the collected wheat seed images; extract some parameters, such as area, plumpness, rectangular, and elongation of the seed, and then build the level model. Experiments showe...
