中文摘要 | 本研究主要探討小蒼蘭在不同海拔高度、種植時期及球莖低溫處理下對生育及花期之影響。 濕冷藏處理結果顯示,各品種對低溫處理反應均為敏感,表現提早開花,開花日數新屋平均約在49-73天、五峰平均約在66-98天;愈早種植者,由於外界溫度較高,故提早開花時間愈明顯;而海拔愈高者(五峰),由於外界溫度較低,則較9,10月種植者平均約晚33-26天開花。花莖長度以新屋表現較佳,長度較高,平昀可達到公分以上,其中以白、紅、黃等色系,較符合經濟利用之長度。小花數在10月、11月定植者,由於五峰試區溫度較冷涼,故表現較佳,平均約可達10朵;12月定植者,因新屋試區氣溫已降為冷涼,故小花數較五峰生產者為多,平均可達10.4朵。 乾冷藏處理結果顯示,各處理對低溫處理反應亦均為敏感,而提早開花,兩地各提早約26天及20天。各園藝性狀如到花日數、花莖長及小花數等表現以平地表現較佳,就整體而言除10月種植者,以溫度處理局10℃下30天及45天兩組在花莖長及小花數等園藝佳狀較差外,其餘各組處理均能符合市場要求品質。又乾冷藏處理其開花期,移出定植後約100天左右開花,較濕冷藏處理者約晚45天開花,但植株生育較佳,切花品質較高,且其處理種球數量可較多、方便而成本較低,故可獲得較高之利潤。 |
英文摘要 | The purpose of this study was to improve the cut flower quality of freesia under different elevations, planting dates low temperatures in Taiwan. Experiments were conducted to study the effects of three planting dates and low temperatures storage of corms on the growth and flowering of freesia at Taoyuan district Agricultural Improvement Station and Wu-Fung branch in 1994. Wet and low temperatures Storage of freesia corms could accelerate early flowering in all the experimental cultivars. Early flowering was found in early planted treatment under high temperature location. Late flowering was found in the high elevation area under low temperature condition. The longest flower stem was obtained from the corms planted at the Station. The white, read and yellow colors cultivars showed the best quality. The number of floret which planted in October and November at Wu-Fung blanch gave the highest yield due to the cooler temperature, while the other which planted in the Station showed the best quality in December. Freesia corms stored under the dry and low temperature conditions could accelerate early flowering in all cultivars. Better characteristics were observed while freesia were grown in low elevation. The cut flower quality could supply for the market demand in all treatments except the stored at 10℃for 30 and 45 days then planted in October. The corms being stored in dry and low temperature treatment resulted in better cut flower quality, growth rate and storage efficiency than those being stored in wet treatment, but delayed flowering dates. |
