Peppermint has considerable commercial value and widely cultivated for essential oil production, especially menthol. The aim of this study was to determine the quantitative expression of pulegone reductase (pr), menthofuran synthase (mfs) and limonene synthase (ls) genes in menthol biosynthesis pathway in Mentha x piperita , using semiquantitative RT-PCR analysis and evaluating menthol producti...
با توجه به محدود بودن منابع انرژی به¬خصوص منابع تجدید¬ناپذیر، اهمیت نحوه مصرف انرژی به¬ویژه در بخش کشاورزی بر کسی پوشیده نیست. هدف از این تحقیق نیز به¬دست آوردن بهره¬وری انرژی، انرژی نهاده (مصرفی) و انرژی ستانده (تولیدی)، بازده خالص انرژی و نسبت انرژی در کشت چغندرقند در استان آذربایجان¬غربی بود. اطلاعات آماری مورد نیاز در رابطه با سطح زیر¬کشت و میزان تولید محصول در سال 1391 از سازمان جهاد کشاور...
In ecological or sustainable intensification, increasing the agricultural productivity and enhancing ecosystem services is possible through improving resource and input-use efficiency. In order to estimate the radiation use efficiency and radiation interception of Fenugreek (Trigonella foenum-graecum) under different treatments of animal manure, a completely randomized block design with three r...
Crop diversification is essential in lowland rice cropping systems to achieve sustainability, improve soil health, and as a climate-resilient practice reduce greenhouse gas (GHG) emissions. A life cycle assessment (LCA) was conducted for the farms west-coast region of India assess environmental impact rice–rice rice–cowpea systems. The (LCIA) evaluated “cradle-to-gate” perspective. higher energ...
Biomass has become an increasingly important resource for energy generation. The influence of the chemical composition on heating value biomass not been a thoroughly studied subject, as shown by bibliometric analysis. It is well known that lignin significantly higher (23.26–25.58 MJ/kg) than polysaccharides (18.6 MJ/kg), while extractives often have HHVs over 30 MJ/kg, depending their oxidation...
In the United States, corn (Zea mays L.) stover has been targeted for second generation fuel production and other bio-products. Our objective was to characterize sugar and structural composition as a function of vertical distribution of corn stover (leaves and stalk) that was sampled at physiological maturity and about three weeks later from multiple USA locations. A small subset of samples was...
The effect of one week of supplementation with a water-soluble fibre (guar gum) was studied in obese women who had lost weight. In study 1 (N=17; mean+/-SEM: age 38.5+/-2.3 yrs; weight 86.8+/-2.3 kg; BMI 32.2+/-0.9 kg.m-2) energy intake and hunger and satiety scores were assessed under free-living conditions. In study 2 (N=14; age 44. 5+/-1.8 yrs; weight 78.8+/-3.1 kg; BMI 29.0+/-0.9 kg.m-2) en...
