Tissue Distribution

Tissue distribution refers to how terpenes accumulate and concentrate across different plant tissues—primarily in trichomes, leaves, stems, and flowers. In cannabis, this spatial patterning is genetically controlled and influences both the plant's biochemical profile and cultivation outcomes. Understanding tissue-specific terpene localization helps breeders predict aromatic expression and phytochemical consistency across plant organs. Most cannabinoid-producing plants concentrate volatile compounds in glandular trichomes on flower buds, though secondary accumulation occurs in fan leaves and surrounding tissues. Lineage records frequently report variation in tissue distribution patterns between parent lines, affecting both breeding stability and post-harvest product uniformity.

Breeders working in terpene-dominant lines select for consistent trichome density and terpene accumulation patterns to ensure predictable aromatic output across harvests. Tissue distribution traits are often assessed through microscopy and phytochemical analysis to identify and stabilize desirable concentration profiles in target organs.
