Which term refers to the condition of being affected negatively by a treatment due to inherent plant characteristics?

The term that accurately describes the condition of being negatively affected by a treatment due to the inherent characteristics of a plant is "susceptibility." This term refers to the sensitivity or weakness of a plant to various treatments, which can include herbicides, fungicides, or other chemical applications. Plants that are susceptible may respond poorly to these treatments because of their genetic makeup, physiological traits, or their current health status.

In the context of weed management, understanding susceptibility is crucial, as it helps in predicting how different species will respond to herbicides or other control methods. Certain plants may have traits that make them more prone to damage from specific treatments, which influences management decisions.

Resistance, on the other hand, refers to a plant's ability to withstand treatments without being adversely affected. Vulnerability implies a general risk of harm but does not specifically denote a negative response to a treatment as directly as susceptibility does. Inoculation is a term related more to introducing a pathogen or a beneficial organism, not to the concept of response to treatment based on plant characteristics.
