Yield-loss models were developed for tobacco infected with Meloidogyne incognita grown in microplots under various irrigation regimes. The rate of relative yield loss per initial nematode density (Pi), where relative yield is a proportion of the value of the harvested leaves in uninfected plants with the same irrigation treatment, was greater under conditions of water stress or with high irriga...

water deficit is an important factor limiting crop production worldwide. drought stress can be managed by improving the availability of soil moisture conserved and selecting drought tolerant genotypes. several physiological indices including stomatal conductance (kl), relative water content (rwc), leaf temperature (tl) and crop temperature stability (cts) along with yield, its components and se...

Novel strategies in coastal protection are needed to cope with climate change-induced sea level rise. They aim at the sustainable development of areas light intensification and land use changes. A promising approach is design nature-based solutions (NbS), complementing safety levels technical infrastructure. However, NbS lack a widespread large-scale implementation. To address this deficit, co-...

polyanionic cellulose polymer is used as an additive in drilling mud in order to decrease water loss and mudcake- thickness. in this study effect of bulk and nanosize polyanionic cellulose on water loss and mud-cakethickness in mud drilling is investigated. polyanionic cellulose nanoparticles are made by using of ball milling. size of nanoparticles is measured by particle size analyzer. polyani...

Birds living in desert environments have been the preferred models for the study of physiological adaptations to water scarcity. Passerine birds living in marine coastal habitats face similar problems, yet physiological adaptations to water conservation in such species have been poorly documented. We measured total evaporative water loss (TEWL) and rates of oxygen consumption (VO2) in three spe...

Article history: Received 15 December 2009 Received in revised form 4 July 2010 Accepted 7 July 2010 The aim of the present study was to investigate the relationship between water, feed intake, relative body weight loss, and the weaning weight of piglets of lactating sows and to analyse the curves of water and feed intake. Data recording was performed on the Hohenschulen research farm of the In...

nowadays, hydrogels are widely used as wound dressings in biomedical applications. similar to other types of the moist (wet) wound dressings, it is necessary to have sufficient information about their dehydration kinetics during the pre-usage period (e.g. storage duration) and also the wound healing process. in this work, hydrogel wound dressings based on polyvinyl alcohol were prepared by cycl...

The objective of this experiment was to study of water relations and chlorophyll in different wheat genotypes and their correlations with grain and biological yields. 21 genotypes of bread wheat were compared in a field experiment as randomized complete blocks design with four replications. The results showed that relative water deficit, relative water loss, excised leaf water retention, cell m...

Shortage and salinity of irrigation water are two major constraints that influence rapeseed production in arid and semi-arid regions of central and southern Iran. In this study, effects of deficit irrigation with different salinity levels and planting methods (in-furrow and on-ridge) as strategies for coping with water and salinity stresses on yield and yield quality of rapeseed were invest...
