Cannabis pollen germination assays, collection-stage effects, loss of viability during cool storage, desiccation/cryopreservation methods, and periodic viability testing.
Visual lesson 10
Pollen viability, germination & storage
Compare staining or non-abortion observations with actual in-vitro pollen germination, then connect collection conditions, moisture, temperature, storage duration, and thawing or rehydration procedures to measured fitness rather than assuming visible pollen is viable.

PracticeCan you explain what the visual is showing?
Why is an in-vitro pollen germination assay more informative than appearance or staining alone for stored Cannabis pollen?
