Physiological and morphological responses of cotton (Gossypium herbaceum L.) under different water regimes
The cotton (Gossypium herbaceum L.) was analyzed for changes in physiological and morphological parameters under the influence of water stress. The deleterious effect of water stress i.e., drought in cotton plants was mainly targeted towards physiological and morphological characteristics. The gas-exchange parameters of net photosynthesis (P N ), stomatal conductance (g s ), electron transport ...
متن کاملPhysiological and biochemical responses of Quercus brantii seedlings to water deficit stress
Water shortage is one of the most important environmental stresses in Mediterranean regions. Poor seedling quality may account for the failure of oak regeneration. To determine the best seed origin of Quercus brantii, we investigated on seedlings collected from 20 mother trees in the Zagros Mountain forests 700 to 2200 m altitudes above sea level. Seedlings from different altitudes were irrig...
متن کاملEvaluating the physiological and hormonal responses of caper plant (Capparis spinosa) subjected to drought and salinity
In order to investigate the effect of drought and salinity stress on caper plant (Capparis spinosa), a factorial experiment including two factors consisting of drought and salinity levels based on randomized complete block design (RCBD) with five blocks were carried out at College of Agriculture, Shiraz University, Shiraz, Iran. After pretreatment, seeds were germinated in petri dishes and then...
متن کاملPhysiological and behavioral responses to different watering intervals in lactating camels (Camelus dromedarius).
During drought periods camels are watered at long intervals, but effects on body fluid homeostasis of lactating camels are not known. It was hypothesized that camels store water after drinking and minimize water losses by diurnal variation in body temperature, changes in behavior, and release of vasopressin. The aim was to find a sustainable watering interval for lactating camels. Seven lactati...
متن کاملMorphological and physiological responses of rice seedlings to complete submergence (flash flooding).
BACKGROUND AND AIMS Reducing damage to rice seedlings caused by flash flooding will improve the productivity of rainfed lowland rice in West Africa. Accordingly, the morphological and physiological responses of different forms of rice to complete submergence were examined in field and pot experiments to identify primary causes of damage. METHODS To characterize the physiological responses, se...
