Steam pretreatment is one of the most efficient pretreatment technologies employed prior to enzymatic hydrolysis of lignocellulosics to obtain high polysaccharide conversion. In this study, steam pretreatment of non-impregnated hemp hurds was investigated at two reactor scales (2 and 10 L) by varying the temperature from 200–230 °C. Glucan recoveries were relatively high (> 82 % of original con...
Selection based on indices is an effective method for breeding complex traits. To assess the efficiency of different selection methods, twenty one accessions of Sainfoin (Onobrychis viciifolia) were evaluated in two environments including drought stress and non-stress conditions according to a randomized complete block design with three replications in 2010. In this study, the selection indices...
Some strawberriy cultivars (Fragaria x ananassa Dutch. cv. Aliso, Selva, Gaviota and Camarosa) were grown hydroponically with five NH4:NO3 mM concentration ratios (0/6 (S1), 0.25/6 (S2), 0.5/6 (S3), 1/6 (S4), 2/6 (S5) and constant nitrate concentration in three replicates for two seasons: Summer and Winter, in greenhouses of Agriculture Faculty of Tehran University. The results are reported as ...
In order to detect the reaction of different potato genotypes to different irrigation regimes and evaluate their water productivity, a research was carried out as a split plot experiment based on a randomized complete block design with three replications in Agricultural Research Center and Natural Resources of Ardabil, Iran in 2015-2016. Five potato genotypes (Agria, Caesar, Savalan, 397081-1 a...
Salinity stress is a brutal environmental stress which decreases the yield production of plants. Questions rise on which of the ionic stress or lack of water has deleterious effects on plants forage dry yield. Also, questions remain on whether the K+ reduction or Na+ accumulation is more important in forage dry yield reduction under salinity stress. The present experiment was conducted to answe...

Common bean (Phaseolus vulgar is L.) demand is increasing with an alarming rate around the world, especially in Latin America, Africa, and Asia. Therefore, increased bean yield per hectare i.s the best way to meet the world demand rather than expansion of area under cultivation. The objectives of this experiment were to determine the genotypic variations for green bean and dry seed yield and ma...
sainfoin (onobrychis viciifolia scop.) is a perennial forage legume has recognized for its feed value and high stability. this experiment was conducted to investigate the relationship among morphological and agronomic traits using multivariate statistical methods including correlation, regression and factor analysis. twenty one accessions of sainfoin were evaluated in a randomized complete bloc...
background & aim: german chamomile is one of the most important medicinal plants. so, assessment of genetic diversity and relationship among the traits are very essential in chamomile breeding programs. determination of the best indirect selection criteria for genetic improvement of essence percent and dry flower yield of german chamomile (matricaria chamomilla l.) populations was investiga...
Methane emission factors are lacking from different livestock species in various production states fed varying diets. The objectives of the present study were to measure effects of physiological state, silage type, and supplemental NDF on DMI, DM digestibility (DMD), and methane emissions of lactating and dry dairy cows using two 4 × 4 Latin squares (5-wk periods) with four lactating (114 DIM ±...
