Acquisition of freezing tolerance during the seed development of Pisum sativum L. cv. Akabana was studied in relation to changes in growth, dry matter accumulation, and water content. Seeds were cooled down rapidly by direct plunging into liquid nitrogen, so that below a determined water content, tissues could vitrify with the consequent survival of seeds. The proportion of seeds that were able...

drought is the main constraint limiting chickpea productivity which makes a considerable difference between the potential and actual yield. in order to evaluate the effect of drought stress on different morpho-physiological characteristics of chickpea, four distinct genotypes were studied in three sampling times (pre-stress, stress and recovery) with three replications. as the results implicate...

Crude protein, fat, water, ash, dry matter and essential amino and fatty acids were analyzed from freshly collected Chironomus plumosus larvae in order to evaluate their suitability as a component for farmed fish diet. The analyses were performed in intact living organisms and in the dry matter. Essential amino acids were determined by LKB 4101 automatic analyzer, while fatty acids were determi...

BACKGROUND The literature abounds with the impacts of drought conditions on the concentration of non-structural compounds (NSC) in peach fruits without distinction as to the direct effect of drought on fruit metabolism and its indirect effect through dilution. Moreover, there is a need to investigate the sensitivity of the fruit composition to progressive water deficit in semi-arid conditions, ...

The Fig (Ficus carica.L) is a woody perennial crop, cultivated worldwide in subtropical regions. Since, salinity is the main concern of fig industry, therefore, studying the pattern of ion absorption and accumulation contribute during the stress in different plant organs can lead understanding the mechanism of tolerance/sensitivity. So, during 2016-2017, seven fig cultivars (‘Sabzʼ, ‘Siyahʼ, ‘S...

An investigation of the drying of spherical food particles was performed, using peas as the model material. In the development of a mathematical model for drying curves, moisture diffusion was modelled using Fick’s second law for mass transfer. The resulting partial differential equation was solved using a forward-time central-space finite difference approximation, with the assumption of variab...

An integrated model WHCNS (soil Water Heat Carbon Nitrogen Simulator) was developed to assess water and nitrogen (N) management in North China. It included five main modules: soil water, soil temperature, soil carbon (C), soil N, and crop growth. The model integrated some features of several widely used crop and soil models, and some modifications were made in order to apply the WHCNS model und...

investigation of physiological responses to water deficit in sesame (sesamum indicum l.) genotypes can help to identify effective mechanisms of plant resistance to stress. therefore, chlorophyll content, proline, soluble carbohydrates, net photosynthesis rate, stomatal conductance, maximum quantum efficiency (fv/fm), plant height and shoot dry weight in a complete block factorial pot experiment...
