Abiotic Stress in Agricultural Crops Under Climatic Conditions

摘要: Crop stress has been identified as one of the problems that threaten global food security. is an injurious deviation from normal physiological processes result into a decline in crop yields. It could be due to biotic factors (biotic stress, i.e. insect pests and disease pathogens) or abiotic (abiotic drought, flooding, radiation nutrient deficiencies). Agricultural crops normally undergo series (photosynthesis, respiration, stomatal functions nutrition) during developmental stages their life cycles are sensitive environmental conditions. The stressed impact on growth development leads biochemical morphological modifications plant species. This chapter details predominantly occurring stresses directly indirectly associated with disruption crops. effects plants range qualitative quantitative changes synthesis type proteins flower bud formation pollination process plant, well impaired uptake resulting poor About 51–82% yield world agriculture lost annually stress. mechanisms four principal (temperature, water, radiation, nutrients, etc.) presented chapter. An understanding agricultural help farmers optimize productivity under changing climate. therefore focuses causes affecting crops, possible coping strategies promote sufficiency.
