Quantitative trait loci (QTL) mapping was used to identify loci controlling various aspects of seed longevity during storage and germination. Similar locations for QTLs controlling different traits might be an indication for a common genetic control of such traits. For this analysis we used a new recombinant inbred line population derived from a cross between the accessions Landsberg erecta (Le...

abstract seed deterioration of seed is one of the most important limiting or even hindering factors in germination. the main purpose of this study was to determine the effects of salicylic acid and gibberellic acid hormonal on improvement and prevailing seed deterioration in two sesame cultivars. this studywere carried out at the department of agronomy and plant breeding seed laboratories of co...

the present work is the successful extension of an improved equation of state (eos) to refrigerant fluids. the objective is the prediction of isothermal and saturated liquid densities of refrigerants. two temperature-independent parameters appearing in the modified eos are closely related to critical point properties of refrigerant fluids. our results showed that, the proposed eos can predict w...

Plants produce a vast array of natural products that mediate their interaction with the environment. Artemisinin is important sesquiterpene lactones, mostly isolated from the Artemisia annua plant, has a wide range of biological activities, including insecticidal, antibacterial and antifungal, antifeedants, and allelopathic properties. Flavonoids (rutin) have attracted attention, primarily as n...

The experiment was conducted in the Agronomy Laboratory of Agrotechnology Discipline, Khulna University, Khulna from 29th August to 17th September, 2009. The experiment was laid out in a Completely Randomized Design (CRD) with two factors and three replications. The aim of the experiment was to study the efficacy of three osmopriming agents viz ., NaCl, KC1 and CaCb with control on seed germina...

The experiment was conducted during October 2014 to December evaluate the effect of different levels salinity on seed germination and seedling growth sunflower. factorial consists three variety sunflower such as BRAC HySun 33, BARI sunflower-2, KU SL-1 five viz. 4, 8, 12, 16 dS m-1 with control. salt stress were varied significantly. (germination energy, capacity speed germination) parameters (...

Predictable seedling establishment is essential for resource-efficient and cost-effective crop production; it is widely accepted as a critically important trait determining yield and profitability. Seed vigour is essential to this, but its genetic basis is not understood. We used natural variation and fine mapping in the crop Brassica oleracea to show that allelic variation at three loci influe...

The objective was to evaluate the quality of sunflower seeds classified according their thickness and passed through seeder-fertilizer dosing system under variation travel speed. A lot M734 by passing a set oblong-hole sieves two thicknesses were selected. portion with only commercial classification also reserved, named as non-classified. biometric evaluation done sowing carried out at 5.0, 6.5...

The objective of this paper was to evaluate the effect of nitric oxide (NO) as a protecting agent of sesame seeds submitted to different concentrations of cadmium. The treatments were: water (control), water increased by sodium nitroprusside (SNP) and other treatments regarding the concentrations of cadmium increased by SNP. The following determinations were done: germination, first count of ge...

as oral skills are increasingly seen as a high priority, phonology and pronuncia tion teaching are occupying a central position in the teaching and learning of other languages. the present study is an attempt to shed some light on identifying and exploring the diffculties of iranian efl learners in phonology and pronunciation. to achieve this goal, 3 male language learners (elementary, intermed...
