中文摘要 | 本試驗的目的在探討不同地區栽培之紅甘蔗,在同一地區、同一栽培 條件下,是否有地方品種差異之表現,並比較其異同及性狀間之相關性。因此利 用所採集30個地方的不同來源族群的蔗種,做為試驗材料,於1979年11月種 植於南投縣之埔里,分別研究地方品種的差異及經濟性狀間之相關程度。不同來 源紅甘蔗的母族群間,原來即有差異存在,而於同一環境下栽培結果,顯示地方 品種間亦有差異性存在。收穫的紅甘蔗莖產量與蔗種來源族群的節間長,呈極顯 著的正相關(r=0.496**),同樣的與來源族群的節間直徑,亦呈顯著的正相關 (r=0.387*)。又甘蔗生育初期的株高、葉寬均與產量呈正相關,相關係數分別為 r=0.659**與r=0.650**,此即表示收穫時之平均蔗莖產量決定生育初期至中期的 營養生長。中部與南部之輪換蔗種似乎不一定能提高紅甘蔗的經濟效益。 |
英文摘要 | The purpose of this experiment was to study the variations of agronomic characters of different original seedlings of fresh edible sugarcane which were evaluated at the same location and cultural condition. Correlations between agronomic characters were also studied. Thirty local varieties of fresh edible sugarcane were planted in poli on November 16, 1979. Those seedlings were varied in their original places. Puli field trial showed that some local varieties of sugarcane were greatly different with the difference of its original population. It seems that sugarcane has varied local varieties in different location. Significant positive correlation (r=0.496**) was found between production and stem internode length from original sugarcane population. Sugarcane also positively correlated with the stem internode diameter from original sugarcane population. Sugarcane production was closely dependent upon whether vegetative growth is vigorous at stages from early growth to midstage. It is not necessary to exchange sugarcane seedlings recurrently to increase production and economic values. |
