CO2 Responses of Winter Wheat, Barley and Oat Cultivars under Optimum and Limited Irrigation

نویسندگان

چکیده

Field crop production must adapt to the challenges generated by negative consequences of climate change. Yield loss caused abiotic stresses could be counterbalanced increasing atmospheric CO2 concentration, but C3 plant species and varieties have significantly different reactions CO2. To examine responses wheat, barley oat enrichment in combination with simulated drought, a model experiment was conducted under controlled environmental conditions. The plants were grown climate-controlled greenhouse chambers ambient enriched (700 ppm 1000 ppm) concentrations. Water shortage induced discontinuing irrigation at BBCH stages 21 55. Positive determined barley, CO2-sink ability low oats. Reactions winter wheat concentration varied greatly terms yield parameters (spike number grain yield). water uptake all cultivars decreased significantly; however same time, water-use efficiency improved Mv Ikva not susceptible fertilization, while no consequent observed for Nádor Nemere.

Cultivar Mixture Cropping Increased Water Use Efficiency in Winter Wheat under Limited Irrigation Conditions

The effects of cultivar mixture cropping on yield, biomass, and water use efficiency (WUE) in winter wheat (Triticum aestivum L.) were investigated under non-irrigation (W0, no irrigation during growth stage), one time irrigation (W1, irrigation applied at stem elongation) and two times irrigation (W2, irrigation applied at stem elongation and anthesis) conditions. Nearly 90% of cultivar mixtur...

Responses of Winter Wheat Yield and Water Use Efficiency to Irrigation Frequency and Planting Pattern

A suitable planting pattern and irrigation strategy are essential for optimizing winter wheat yield and water use efficiency (WUE). The study aimed to evaluate the impact of planting pattern and irrigation frequency on grain yield and WUE of winter wheat. During the 2013-2014 and 2014-2015 winter wheat growing seasons in the North China Plain, the effects of planting patterns and irrigation fre...

Remobilization of water soluble carbohydrates in non-leaf organs and contribution to grain yield in winter wheat under reduced irrigation

The remobilization of water soluble carbohydrates (WSC) has an important role for grain yield. This study investigated the accumulation and remobilization of WSC in non-leaf organs (chaff, upper stem, and lower stem) and their contribution to grain yield, under different irrigation levels (rainfed, reduced irrigation, and full irrigation) and seeding rate treatments (450, 600 and 750 plants...
