Effects of External Potassium (K) Supply on Drought Tolerances of Two Contrasting Winter Wheat Cultivars
BACKGROUND Drought is a common stress limiting crops growth and productivities worldwide. Water deficit may increase cellular membrane permeability, resulting in K outflow. Internal K starvation may disorder plant metabolism and limit plant growth. However, it is seldom reported about the effects of external K on drought tolerance of contrasting wheat cultivars. METHODOLOGY/PRINCIPAL FINDINGS...
متن کاملPhysiological responses of two wheat cultivars to soil drought.
Young plants of the two wheat cultivars Katya and Prelom, differing in their reaction to drought in the field, were grown in soil in pots, and their water status was assessed as well as the intensity of gas exchange, chlorophyll fluorescence, and accumulation of compatible solutes and hydrogen peroxide after 7 days of dehydration. It was established that cv. Katya displayed markedly better tole...
متن کاملGenetic diversity in spring wheat cultivars and relationships between traits under terminal drought stress
For evaluation of the traits related to water deficit stress in 20 spring wheat (Triticum aestivum L.) cultivars and subsequently determination of the most tolerant and sensitive cultivars, an experiment was carried out in split plot based on randomized complete block design (RCBD) in the research farm of the University of Tabriz, Iran during 2010-2011 and 2011-2012 crop seasons. The first fac...
متن کاملYield Components and Grain Yield Responses of Four Wheat Cultivars to Growth Retardant Cycocel under Terminal Drought Stress Conditions
This research was carried out to study the grain yield, yield components and NDVI (normalized difference vegetation index) responses of four wheat cultivars to growth retardant cycocel under terminal drought stress conditions. The experiment was laid out as a split split plot with three replicates at the experimental farm of the School of Agriculture, Shiraz University, Shiraz, Iran in 2016-201...
متن کاملContrasting response of biomass and grain yield to severe drought in Cappelle Desprez and Plainsman V wheat cultivars
We report a case study of natural variations and correlations of some photosynthetic parameters, green biomass and grain yield in Cappelle Desprez and Plainsman V winter wheat (Triticum aestivum L.) cultivars, which are classified as being drought sensitive and tolerant, respectively. We monitored biomass accumulation from secondary leaves in the vegetative phase and grain yield from flag leave...
