中文摘要 | 本研究主要探討修剪對仙丹花(Ixora chinensis Lam.) 生長與開花的影響。於較 高溫之 4 月、6 月或 8 月修剪時,修剪後新芽萌發較快,枝條較長,至下次開花所需期間 較短;若於較低溫之 2 月、10 月或 12 月修剪,則修剪後約需 5 週至 6 週之時間,才見 新芽萌出,且枝條生長緩慢,故切花長度較短,花序亦較小,至下次開花所需時間亦較長。 不同修剪程度明顯影響切花的品質。低溫時修剪至離地 50 公分之花莖較修剪 70 公分為長 。唯 6 月修剪時,反以修剪至離地 70 公分之花莖較長。 故於高溫時,不宜過度強剪。全 年中則以較高溫時宜弱剪,較低溫時可較強剪。 花開時,以留 4 節之修剪,其切花品質佳 ,其中又以春季採收之切花品質最好,且 2 次採花間之日數亦較短。 |
英文摘要 | In two-year pruning experiment of Ixora (Ixora chinensis Lam), when plants were pruned in April, June or August, new shoots grew faster, longer and the days to flowering shortened. If plants were pruned in February, October or December, the new buds sprouted five or six weeks later after pruning, the shoots were very short,and the time to flowering was delayed due to slow growing. The effect of the pruning height on the flower quality of Ixora was obvious. Hedging at 50 cm height in low temperature resulted in longer flowering shoots than those at 70 cm. In short, light pruning could be adopted while the temperature was high, and heavy pruning should be used in low temperature. Better flowers could be obtained in a shorter period of time if flowers were cut at the 4th node from the cane base at blooming. |
