Seeds, Rootstocks & BreedingHow can a nursery separate seed-source effects from collection-date effects?
Collect the sources over comparable periods where practical, and retain separate dates within each source. If one source is collected fresh while another arrives after prolonged holding, their results describe different handling histories as well as different sources. Compare matched collections first. An unmatched comparison can still inform purchasing, but it cannot isolate an inherited germination advantage.
