Rooting Vigor

Rooting vigor is not a terpene in the classical sense, but rather a phenotypic trait breeders observe during vegetative propagation—particularly when working with clones and cuttings. This trait describes how quickly and robustly a cutting develops new root tissue, often correlated with certain monoterpene and sesquiterpene profiles, though causation remains unclear. Lineage records frequently report that some cultivars show consistently stronger root initiation across multiple generations, suggesting possible genetic predisposition. The trait is valued in breeding programs focused on propagation efficiency and clone stability, as faster-rooting genetics reduce nursery time and lower transplant loss. Environmental factors (hormone application, light, humidity, substrate) heavily influence expression, making controlled trials necessary to distinguish genetic from phenotypic components.

Breeders working in clone-heavy production systems prioritize rooting vigor to streamline propagation. Crosses selecting for this trait can reduce nursery bottlenecks and improve cut viability in commercial or breeding operations.
