Systemic Acquired Resistance
Systemic Acquired Resistance (SAR) is not a terpene, but rather a plant defense mechanism that cannabis breeders and growers study for its potential role in whole-plant immunity. When a plant encounters a pathogen or stressor in one area, SAR signals activate chemical defenses throughout the entire organism—a process mediated by salicylic acid and other signaling compounds. While terpenes themselves are volatile aromatic molecules distinct from immune signaling pathways, certain terpene profiles are often observed in cultivars bred for robust disease resistance. Understanding SAR is relevant to breeding programs focused on pest resilience and environmental stress tolerance, rather than aroma or flavor.

Breeders working on disease-resistant genetics study SAR activation as a marker of plant vigor and survival potential under challenging cultivation conditions. Cultivars exhibiting strong SAR traits may require fewer external interventions, making them valuable for sustainable breeding objectives.
