摘　　要：对引进的5个种源地的栾树属植物种子进行种子试验,并对1年生苗的生长节律及生长量进行观测。结果表明：引进的5个种源地的栾树属植物种子在千粒重、含水量及发芽率等方面均表现出极显著差异,综合看来,江苏、湖南、浙江的种子质量较好;栾树属植物在海南气候条件下4~5月和9~11月生长较快,5~9月生长速度稍有下降,结合生物量测定结果表明,江苏、湖南、浙江种源的栾树属植物适合在海南种植。The seed test carried out on seed of 5 Koelreuteria Laxm provenances, the biomass and growth rhythm of one year old seedling were also observation. The results showed that there were significant differences at 1000 grain weight, moisture and germination rate of 5 Koelreuteria Laxm provenances. Comprehensive view, the quality of seed from Jiangsu , Hunan and Zhejiang were better; In Hainan climate conditions, Koelreuteria plants grew faster from April to May and September to November, and then declined slightly from May to September. Combined with biomass determination results, Koelreuteria Laxm from Jiangsu , Hunan and Zhejiang provenance are suitable for cultivation in Hainan.
