Abstract: The acclimatization of five wild Primroses (Pfrimula forrestii Franch, P.poissonii Franch, P.bulleyana Forr., P.secundiflora Franch and P.sikkimensis Hook,)from N.M.Yunnan is reported in the present paper. Their seeds were collected from different places with various climate and ecological environments. Through observation for the process from "seed to seed" in different controls including mediums, temperature, light duration etc, we come out with three convincing arguments: (1) All seeds possess a high germination adaptability in cultivation in Kunming, though the germination capacity of each species seeds in different medium is uneven.

Key words: Primula
