Trichome sampling units, bract versus sugar-leaf context, microscopy and imaging considerations, anatomical variability, and reproducibility of trichome assessment.
Visual lesson 03
Where to inspect
Compare glandular trichomes on representative flower bracts, nearby sugar leaves, and different canopy or flower positions so one convenient sample is not assumed to represent the entire inflorescence.
Interactive academic visual
Where to inspect trichomes
Standardize tissue, canopy position, magnification and repeat samplingFlower bracts
For floral maturity observations, glandular trichomes on representative flower bracts are generally more relevant than those on surrounding leaf tissue.
