Miekal: Here's info per Deno. amelanchier alnifolia - ref 43. CH. 10. Chapter 10 discusses outdoor exposure and oscillating temperatures. The temperatures oscillate between 40 and 70 but I don't know what ref 43 means. Perhaps someone else can explain this. Sorry... prunus virginiana - no info in vol. 1 mahonia aquifolium - over many cycles. Seeds WC for 7d and DS 6m at 70 germ. 40(1%)-70(4%)-40(4%)-70(3%)-40(39% in 3-12 w. This is for seed collected in July. The cycles are 3months each. rubus parviflorus - 70 GA-3(25% in 4-7w), 70D(none) and 40-70D(6%)."Eugene Zielinski communicated that it germ. in April in outdoor treatment." I hope this helps.
