Elevated CO2 Reduced Floret Death in Wheat Under Warmer Average Temperatures and Terminal Drought
Elevated CO2 often increases grain yield in wheat by enhancing grain number per ear, which can result from an increase in the potential number of florets or a reduction in the death of developed florets. The hypotheses that elevated CO2 reduces floret death rather than increases floret development, and that grain size in a genotype with more grains per unit area is limited by the rate of grain ...
متن کاملcrop models efficiency and performance under elevated atmospheric co2
abstract radiation, water and co2 are three major resources requirement for crops growth and development and within a wide range, increasing each of them would increase the biosphere productivity. higher usage of fossil fuels is increasing the atmospheric co2 and according to known crop physiological functions, such conditions should increase the crops production. however there is a possibility...
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 کاملElevated CO2, drought and soil nitrogen effects on wheat grain quality
• The likely consequences of future high levels of atmospheric CO 2 concentration on wheat ( Triticum aestivum L.) grain nutritional and baking quality were determined. • Two free-air CO 2 enrichment (FACE; 550 mmol mol − 1 ) experiments were conducted at ample (Wet) and limiting (Dry) levels of irrigation, and a further two experiments at ample (High-N) and limiting (Low-N) nitrogen concentrat...
متن کاملElevated CO2 maintains grassland net carbon uptake under a future heat and drought extreme.
Extreme climatic events (ECEs) such as droughts and heat waves are predicted to increase in intensity and frequency and impact the terrestrial carbon balance. However, we lack direct experimental evidence of how the net carbon uptake of ecosystems is affected by ECEs under future elevated atmospheric CO2 concentrations (eCO2). Taking advantage of an advanced controlled environment facility for ...
