The present experiment was done to know the germination ability for the effective propagation of Rhododendron fauriei for. rufescens. The optimum temperature for seed germination of R. fauriei for reference might be 20 degrees Centigrade. The rate of seed germination varied with the storage of seed and decreased when the seeds were washed in water for a long period of time. Among the thiourea treatments, one percent level gave the highest rate of seed germination was apparent in the early stage of germination but not in the late stage. In the plots of IAA (Indole Acetic Acid) and GA (Gibberellic Acid) treatment kept in darkness, few of the seed germination were seen in the treatment with IAA, while there was fifty percent of seed germination with the treatment of GA
