It is known that many abiotic stresses, such as mineral deficiency, drought, UV-B radiation, wind and low temperatures, alter the quantity and composition of lignin in several species [1]. The aim of this work was to verify if the drought stress may cause changes in the quantity and composition of lignin in Eucalyptus globulus Labill and in the hybrids E. urograndis (E. urophylla x E. grandis) ...

Non-irrigated crops in temperate climates and irrigated crops in arid climates are subjected to continuous cycles of water stress and re-watering. Thus, fast and efficient recovery from water stress may be among the key determinants of plant drought adaptation. The present study was designed to comparatively analyze the roles of drought resistance and drought recovery in drought adaptation and ...

Sorghum [Sorghum bicolor (L.) Moench] grain yield is severely affected by abiotic and biotic stresses during post-flowering stages, which has been aggravated by climate change. New parental lines having genes for various biotic and abiotic stress tolerances have the potential to mitigate this negative effect. Field studies were conducted under irrigated and dryland conditions with 128 exotic ge...

A study was performed to study the effect of drought stress on protein changes of five wheat genotypes. Wheat genotypes were planted in early November, growing season of 2008-2009. The experiment was carried out in a factotial design with three replications. Two drought stress levels (irrigated and Non irrigated) and five genotype of wheat (F103-L-1-12//PONY/OPATA, F1.158/FDL//BLO/3/SH14414/CRO...

A field experiment with two sets, each comprising 13 chickpea genotypes with three replications was carried out during Rabi 2012-2013 in stress and non-stress conditions. The objective of the reported research was to study the response of chickpea genotypes in drought stress and to screen the appropriate genotypes performing better in water deficit and irrigated conditions. Three genotypes TG12...

To determine root growth and grain yield of winter wheat (Triticum aestivum L) under moderate drought stress, a nursery experiment and a field trial were conducted with or without water stress using three representative cultivars released in different years: CW134 (old landrace), CH58 (modern cultivar) and CH1 (new release). In the nursery experiment, plants were grown in soil-filled rhizoboxes...

Common bean (Phaseolus vulgaris L.) is the most important food legume in the diet of poor people in the tropics. Drought causes severe yield loss in this crop. Identification of traits associated with drought resistance contributes to improving the process of generating bean genotypes adapted to these conditions. Field studies were conducted at the International Center for Tropical Agriculture ...
