Which term refers to the resistance of plants to pests or diseases due to environmental conditions?

The term that accurately describes the resistance of plants to pests or diseases as a result of environmental conditions is abiotic tolerance. This term specifically refers to a plant's ability to withstand or adapt to non-living environmental factors, such as temperature, water availability, soil composition, and other abiotic factors. These environmental conditions can significantly influence a plant's health and its ability to fend off biotic stressors like pests and diseases.

In the context of plant health, when conditions such as drought or nutrient deficiency are optimized, plants can exhibit increased resistance to the pressures imposed by pests or pathogens. This connection is vital for understanding how plants can be supported through practices that enhance their abiotic resilience, ultimately leading to improved crop yields and sustainability.

Other terms mentioned, while related to plant health, do not specifically denote the influence of abiotic factors on resistance to pests and diseases. Thus, abiotic tolerance is the most relevant and correct term in this scenario, as it underscores the impact of environmental conditions on a plant's defensive capabilities.
