摘要: 朱槿夏季扦插時以頂梢插穗的發根率較高。'Como'品種以頂梢插穗處理NAA粉劑濃度2g/kg時最高之發根率為77.8%。'0112'品種發根率較差,以頂梢插穗處理NAA濃度2g/kg時最高之發根率僅16.7%。'京都'品種則以頂梢插穗處理NAA濃度0.5-2g/kg時有較高之發根率為83.3-87.5%。播種前種子以常溫或50℃溫水浸種15小時處理,發芽率無顯著差異。發芽勢則以常溫浸種處理較優於50℃溫水浸種處理。不同雜交組合獲得之種子,發芽率介於27.7%至44.3%之間。
The rooting rate of H. rosa-sinensis L. terminal cuttings was better than woody cuttings in the summer. The optimum NAA concentration for terminal cuttings of 'Como' was 2 g/kg, with the rooting was 77.8%. The rooting rate of '0112' terminal cuttings powered with NAA 2 g/kg was 16.7%. The rooting rate of 'Kyoto' terminal cuttings powered with NAA 0.5 to 2 g/kg was 83.3-85.2%. Seed germination rate was not different between soaked 15 hours in water at room temperature or in 50℃ warm water, and the germination rate of hybrid seeds was 22.7-44.3 %. The germination strength of seeds soaked in water at room temperature was better than those in 50℃ warm water.
