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

摘要： 报道了采自云南西北部的5种野生报春(灰岩皱叶报春Primula forrestii Franch,海仙花P.poissonii Franch，橘红灯台报春P.bulleyana Forr.,偏花报春P.secundiflora Franch和钟花报春P.sikkimensis Hook,)的引种驯化研究。将采自不同地方，不同气候以及不同生态环境下的种子，通过在不同控制条件下包括基质、温度、光照等 “从种子到种子”整个过程的实验观察，得出结果如下：(1)虽然每个种的种子在不同的基质中萌发率参差不齐，但所有种子在昆明栽培条件下都有高的萌发适应性。(2)虽然它们的开花时间不同(海仙花和偏花报春除外)，但所有从播种获得的植株要10～16个月才能开花，与野生报春相比栽培的报春花花期提前2～3个月，灰岩皱叶报春还出现了重瓣花。(3)苗圃的报春花结实率比在野生状态下的低，人工授粉后座果率有所提高。
