Is it true that Scarification improves seed germination rates?
Partly. Several species-specific studies and references report that scarification raises germination rates in particular seeds, while at least one study found scarification did not increase germination and another found non-scarified seeds performed best. The evidence covers individual species rather than a general rule.
