Potential damage by biotic stress Fungi cause more diseases in plants than any other biotic stress factor Over 8,000 fungal species are known to cause plant disease Not many plant pathogenic viruses exist, but they are serious enough to cause nearly as much crop damage worldwide as fungi Microorganisms can cause plant wilt, leaf spots, root rot, or seed damage Insects can cause … Environmental resistance factors include factors that are biotic (living) and abiotic (non-living). Tolerance Biotic potential, the maximum reproductive capacity of an organism under optimum environmental conditions.It is often expressed as a proportional or percentage increase per year, as in the statement “The human population increased by 3 percent last year.” It can also be expressed as the time it takes for a population to double in size (doubling time).
