中文摘要 | 樹型聖誕紅僅佔聖誕紅總產量的0.05% ,因其樹型主幹的培養耗時,增加管理成本,同時也缺乏一套完善的樹型商品生產流程。聖誕紅實生植株具有節間長、莖直徑較粗、生長快且較強健等特性,同時實生聖誕紅不易分枝且主幹葉片容易落葉,在樹型苗生產過程能省去摘除主幹側芽和葉片的勞力花費。實生苗除葉摘心處理後能有8 個節位萌發腋芽,強摘心及輕度摘心處理最多僅有5 個腋芽萌發。除葉摘心處理植株可產生6 枝超過5 公分的側芽,同時側芽長度呈現由頂而下漸增的趨勢,使植株呈現一美觀樹型。利用高度20-25 公分之實生苗進行至少3 次除葉摘心,能生產盆花規格為高度45-50 公分的樹型聖誕紅。 |
英文摘要 | The new bitter gourd variety Hualien No.3 is an F1 variety. It has the characteristics of strong growth, early female flowering, strong fruit setting and good eating quality. The parental plants were collected from domestic Jian area in 1998. Then in 2002, a breeding line WB15 has been, with good breeding quality of multiple objectives, reproduced after a series of purification, selection and crossing for years. On November 10, 2007, WB15 was formally named Hualien No.3, after some tests including the combining ability test of F1 crossing, comparison test, regional trials and density trials. Bitter gourd Hualien No.3 is a vine with lots of branches. Its female flowers bloom from the twenty section of the main vine. The flowering period starts about 31 days for spring crop and 29 days for summer crop. Its exocarp is green and the face of the fruit has the process of pearls and bars. The fruit is long ovaloid and the weight of 160 to 200 grams. It can be reaped after flowering 20 to 25 days for spring crop and 20 days for summer crop. The total product each hectare is approximately 19.2 metric tons for spring crop and 13.6 metric tons for summer crop. Seedling nursing days are about 14 to 20, setting to flowering days 30, and setting to reaping days 55 for spring crop and 50 for summer crop. Total reaping days are 45 to 60. Total surviving days are 110 to 140. |
