  • Plants are continuously affected by a variety of environmental factors. Whereas biotic environmental factors are other organisms such as symbionts, parasites, pathogens, herbivores, and competitors, abiotic factors include parameters and resources which determine plant growth like temperature, relative humidity, light, availability of water, mineral nutrients, and CO 2 , as well as wind, ionizing radiation, or pollutants (Schulze et al. 2002 ) .
