The values of heritability were higher for yield and quality parameters, but for earliness traits heritability was moderate. The results of correlation coefficients for days to flower initiation, boll weight, GOT%, sympodia branches and boll number per plant showed significant positive genotypic and phenotypic associations with seed cotton yield. Maximum values of direct effects on yield were also observed for these traits. The results of principal component analysis revealed that 4 four components contributed 78% of total variation. Cluster analysis showed that genotypes in cluster-II viz: FH-488, FH-490, FH-142, FH-451, FH-452, FH-453, FH-455 are exploitable not only for hybridization purpose but also some of the genotypes in this cluster may be recommended for testing in national and provincial trials. &nbsp;</p> 2018-05-15T17:17:47+0430 ##submission.copyrightStatement## Potential role of some biofertilizers, plant nutrients and a biocide for the management of reniform nematode, Rotylenchulus reniformis infecting sunflower in Egypt 2018-05-14T23:31:44+0430 Ahmed El-Sayed Ismail <p>The reniform nematode, <em>Rotylenchulus reniformis</em> attacks a wide range of crops including sunflower, <em>Helianthus annuus</em> in Egypt as well as in many parts of the world. Elimination of the nematodes has received attention to minimize damage to plants. Thus, the present study aims to estimate the probable effects of three rates of some biofertilizers, plant nutrients and a biocide on the development of <em>R. reniformis</em> in sunflower and growth of the plant. Three Egyptian of bio-fertilizers (BF), i.e. Nitrobien (at doses 0.034, 0.068 and 0.136), Rizobactrein (at doses 0.017, 0.034 and 0.068) and Blue-green (at doses 0.2, 0.4 and 0.8); and three Egyptian plant nutrients (PN) i.e. Citrein (at doses 0.1, 0.2 and 0.4), Kotangein (at doses 0.01, 0.02 and 0.03) and Kapronite (at doses 1.0, 2.0 and 4.0) as well as the biocide Nemaless (at doses 0.005, 0.01 and 0.02) were evaluated as&nbsp; a lower rate, the recommend rate and a higher rate; respectively for control of <em>R. reniformis</em> and improvement of sunflower cv. Giza 101 under greenhouse conditions 30 ± 5 ºC. All the evaluated compounds significantly reduced (P? 0.05 and/ or 0.01) the number of juveniles in soil, swollen females and egg-laying females on roots. The reduction varied greatly according to the type of experimented products and rate of application. The highest reduction in the nematode populations, swollen females and egg-laying females was attained with seed coating by Rizobactrein followed by Nitrobien as bio-fertilizers while, the least reductions were obtained by using Blue-green as alga biofertilizer followed by Nemaless as a biocide. Application of the plant nutrients, Kotangein as seed coating and Kapronite as soil amendment were effectively decreased the development of the nematode stages. Citrein as a foliar spray nutrient was the least effective. Generally, Rizobactrein and Nitrobien as biofertilizers; Kapronite and Kotangein as plant nutrients proved to be the most effective for controlling <em>R. reniformis</em> and gave the greatest growth of sunflower plants as compared with the rest treatments. &nbsp;</p> 2018-05-14T23:30:40+0430 ##submission.copyrightStatement## Exogenous application of salicylic acid improves tolerance of wheat plants to lead stress 2018-04-13T22:40:26+0430 Saud Ali Dayl Alamri Manzer H Siddiqui Mutahhar Yahya Al-Khaishany Hayssam Mohamed Ali Abdullah Al-Amri Hala Khalid AlRabiah <p>Salicylic acid (SA) acts as a signaling molecule and plays an important role in various physiological and biochemical processes in plants. The aim of the present study was to evaluate the role of SA in the enhancement of lead (Pb) tolerance in wheat (<em>Triticum aestivum</em>) plants. When 2–3 true leaves had appeared, treatments were applied to the plants. The treatments were as follows: (i) no addition of SA and Pb (control), (ii) 2 µM SA + 0 mM Pb, (iii) 8 µM SA + 0 mM Pb, (iv) 0 mM SA + 2 mM Pb, (v) 2 µM SA + 2 mM Pb, and (vi) 8 µM SA + 2 mM Pb. One-way analysis of variances (ANOVA) was used to compare the means, and Duncan’s multiple-range test (DMRT) was used to determine significant (<em>P &lt; 0.05</em>) differences among the individual means of treatments. Exposure of Pb severely affected wheat plants by reducing plant height, fresh and dry weight, photosynthetic pigments (<em>Chl a</em> and <em>b,</em> <em>Chl a:b</em>) and carbonic anhydrase enzyme activity, and by enhancing <em>Chl </em>degradation, electrolyte leakage (EL), malondialdehyde accumulation. Also, Pb treatment increased the accumulations of proline and total soluble carbohydrates (TSC) and activities of antioxidant enzymes [superoxide dismustase (SOD), catalase (CAT), and peroxidase (POD)]. However, application of SA induced biosynthesis of pigments by suppressing <em>Chl</em> degradation, and EL and malondialdehyde accumulation. Furthermore, SA treatments further enhanced the production of proline and TSC, and the activities of SOD, CAT, and POD. SA directly or indirectly improved physiological processes, which helped wheat plants to overcome the oxidative damage induced by Pb toxicity. Also, this study reveals that exogenous application of SA is beneficial for plant growth and development of wheat plants by suppressing ill effects of heavy metal stress. Therefore, this study opens up the hidden role of SA in tolerance of plants to heavy metal toxicity to explore its new regulatory role and defensive mechanism at physiological and molecular levels. Also, exogenous application of SA could be beneficial for sustainable agriculture.</p> 2018-04-13T14:50:02+0430 ##submission.copyrightStatement## Some Selected Engineering Properties of Seven Genotypes in Quinoa Seeds 2018-04-13T22:40:26+0430 Ebubekir Altuntas Altuntas Ismail Naneli Mehmet Ali Sakin <p>Some selected engineering properties (geometrical, volumetrical, colour and mechanical) properties of seven genotypes in <em>quinoa</em> seeds were determined and compared in this study. <em>Che. quinoa (red) </em>genotype had the lowest geometric mean diameter and surface area, whereas <em>Che. quinoa (black)</em> genotype had the highest values among 7 quinoa genotypes, for these properties. The bulk density, true density, and porosity of quinoa genotypes were determined between 713.6 and 824.4 kg/m<sup>3</sup>, 766.9 and 911.4 kg/m<sup>3</sup>, 6.95 and 15.03% respectively. <em>Che. quinoa (Q11)</em> genotype had the lowest bulk and true densities, whereas <em>Che. quinoa</em> <em>(Ames)</em> genotype had the highest bulk and true density values among quinoa genotypes. The sphericity and seed volume values of <em>Che. quinoa (black)</em> genotype observed in quinoa genotypes were lower than the other quinoa genotypes. The lowest hue angle and chroma colour characteristics values were found as 33.61 and 8.41 in <em>Che. quinoa (black)</em> genotype among quinoa genotypes, respectively. The static friction coefficient and the angle of repose in quinoa genotypes were determined between 0.477 and 0.955, 14.09 and 23.57° respectively.&nbsp; The lowest rupture force and hardness were found in <em>Che. quinoa (black)</em> genotype, whereas, the highest rupture force and rupture energy were found in <em>Che. quinoa (PI)</em> genotype among <em>quinoa</em> genotypes. The study provides an opportunity that some engineering properties (including physical and mechanical properties in the quinoa seeds of seven genotypes may be useful in designing of the related equipment for postharvest handling and processing operations (harvesting, separating, processing, packing, and transportation). &nbsp;</p> 2018-04-13T00:00:00+0430 ##submission.copyrightStatement## Conceptual Design and Feasibility Study of a Multi-Feed Integrated Biomass Conversion System 2018-04-13T22:40:25+0430 Saeed Ghanbari Venkatesh Meda Catherine Hui Niu <p>Biomass is recognized as a potential source for sustainable production of fuels. Forestry residuals has been used for the small-scale production of biodiesel since early 1800s. However, the biofuel market has not been suitable in recent decades due to the pronounced drop in the worldwide price of petroleum. In addition, environmental issues, low reactor yield, and uncertainties in biomass feedstock have challenged process design engineers. Hence, extensive research has been reported to address these issues. Pyrolysis and gasification processes can produce a wide range of fuels, chemical, solvents, and other valuable products from biomass. Scholars attempted to optimize various operating parameters, find innovative approaches to increase the reaction yield, and develop novel product upgrading techniques such as bio-oil upgrading; yet, limited studies were focused on implementation of these methods for a multi-feed integrated biomass production plant. Recent findings have created the foundational blocks for design of high-tech integrated biomass conversion systems. This paper is focused on conceptual design and feasibility study of such systems incorporating the strategies and technologies at hand. The available biomass conversion technologies for different feedstocks are combined in this design. To this end, a new plant is designed and simulated in ASPEN PLUS simulator using ASPEN Economic Analyzer to perform an economic analysis. Techno-feasibility results suggest that this plant is not profitable even after incorporating the new technologies and optimizing the system.</p> 2018-04-12T11:48:16+0430 ##submission.copyrightStatement##
