A factor of an experiment is a controlled independent variable; a variable whose levels are set by the experimenter. A factor is a general type or category of treatments. Different treatments constitute different levels of a factor.
Any process that results in a change in state or activity of a cell or an organism (in terms of movement, secretion, enzyme production, gene expression, etc.) as a result of an abiotic (not derived from living organisms) stimulus.
Plant abiotic stress traits may be manifested in either the whole plant (PO:0000003) or in parts of the plant, as a result of the exposure to an abiotic plant stress (PSO:0000012). Responses to plant stresses may vary from resistance to susceptibility, with varying levels of tolerance. Abiotic stresses are those resulting from non-living factors such as drought, salinity or temperature extremes.

A process in which a symbiont alters or subverts the response of its host to an abiotic (non-living) stimulus. The host is defined as the larger of the organisms involved in a symbiotic interaction.

An abiotic disease is a physiological, non-parasitic, non-infectious disease caused by numerous phenomenons such as: accidents linked to climate or weather, nutritional disorders, phytotoxicity linked to treatment, genetic anomalies, or any other environmental factors or human interventions, ...
An abiotic vector is a non-living phenomenon able of successfully transporting a pathogen agent from an infected living organism to another healthy living organism or to its environment or its consummed resource. Transport is considered effective if it enables the pathogen agent to be maintained in the environment in question. In plant health, water and wind are two essential abiotic vectors involved in the spread of plant bioaggressors over varying distances (e.g. water/bacteria; wind/insect vectors).
Physical, chemical and other non-living environmental factors. They are essential for living plants and animals of an ecosystem, providing the essential elements and nutrients that are necessary for growth. The abiotic elements also include the climatic and pedologic components of the ecosystem.
All traits related to stress caused by non-living
stressors. Abiotic stress is defined as the
negative impact of non-living factors on the
crop/plants. Most common abiotic stressors are
drought, waterlogging, high/low temperatures,
mineral toxicities/deficiencies, hail, and wind.
A condition that varies between observation units, by taking different values or modalities, assessing the effect of which is the goal of the study. A factor may be biotic (pest, disease interaction) or abiotic (treatment, cultural practice) in nature. It must have at least two values or modalities.
Any toxin secreted by bacteria, viruses, fungi or protozoa enabling them to achieve colonisation of a niche in the host, inhibit or evade the host's immune response, enter and exit cells, or obtain nutrition from the host.
