摘要

本試驗收集台灣鼠李、羅芙木、魯花樹及槴子花等4種本土植物，以種子在不同溫度萌芽和插穗扦插在不同發根劑濃度成活的繁殖方式，探討最適合的繁殖方法。結果顯示台灣鼠李以種子萌芽方式繁殖較能獲得實生苗，但在30℃高溫環境之萌芽率僅5%，插穗扦插成活率均在20%以下。在春季，羅芙木插穗沾取發根劑扦插繁殖可獲得53-60%的成活率，種子在30℃處理有46.7%的萌芽率，魯花樹插穗不論有無沾取發根劑均可獲得100%的成活率。黃槴子不論在春、夏、秋季以扦插方式繁殖幼苗的成活率幾達100%，氣溫和降雨對其影響不大。

Four species of native plant included Rhamnus formosana Matsum、Rauwolfia verticillata (Lour.) Baillon、Scolopia oldhamii Hance、Gardenia jasminoides Ellis were collected in Taiwan. The plant characterization, the optimal germination temperature by seedling and IBA concentration of cuttage survival rate were examined. The results showed that it would gain Rhamnus formosana Matsum seedling by seed germination. And the seeds had 5% germination rate by 30℃ treatment and 20% cuttage survival rate only. Cuttage of Rauwolfia verticillata (Lour.) Baillon treated with IBA had 53-60% survival rate in Spring and got 46.7% germination rate in 30℃ treatment. Cuttage of Scolopia oldhamii Hance treated or non- with IBA had 100% survival rate. The survival rate of Gardenia jasminoides Ellis cottage was 100% in spring, summer or autumn, and rain fall were not mainly effects.
