The relationship between biotic stress and plant yield affects economic decisions as well as practical development. The impact of biotic injury on crop yield impacts population dynamics, plant-stressor coevolution, and ecosystem nutrient cycling. [3] Biotic stress also impacts horticultural plant health and natural habitats ecology. It also has ...
Plant stress research looks at the response of plants to limitations and excesses of the main abiotic factors (light, temperature, water and nutrients), and of other stress factors that are important in particular situations (e.g. pests, pathogens, or pollutants). Plant stress measurement usually focuses on taking measurements from living plants.
Plants can protect themselves from abiotic stress in many different ways, and most include a physical change in the plant’s morphology. Phenotypic plasticity is a plant’s ability to alter and adapt its morphology in response to the external environments to protect themselves against stress. [ 2 ]
He is a member of the Order of Australia and his contributions spans physiological response of crops and trees to water deficits, rainfall-use efficiency, climate change implications for crop production, and various abiotic and biotic stress factors affecting plant growth and productivity. [1] Turner has authored and co-authored over 400 ...
A plant's first line of defense against abiotic stress is in its roots. If the soil holding the plant is healthy and biologically diverse, the plant will have a higher chance of surviving stressful conditions. [10] The plant responses to stress are dependent on the tissue or organ affected by the stress. [8]
Ecophysiology (from Greek οἶκος, oikos, "house(hold)"; φύσις, physis, "nature, origin"; and -λογία, -logia), environmental physiology or physiological ecology is a biological discipline that studies the response of an organism's physiology to environmental conditions.
Issues of sulfur nutrition of crop plants, with focus on resistance to abiotic and biotic stress were later one of her main research subjects. In 2001 Haneklaus coined with Ewald Schnug the term ‘Sulphur-Induced Resistance’ (SIR) which will become a major focus in the research portfolio of FAL/JKI.
Plant hormones are signalling molecules produced within the plant (i.e. they are endogenous). Hormones regulate cellular processes in targeted cells locally and can be moved to other parts of the plant. Examples of plant hormones are auxins, cytokins, gibberellin, ethylene, abscisic acid, salicylic acid and jasmonates.
