芻料用高粱品系生產潛力評估
The assessment of yielding potential in forage sorghum lines
摘要
本研究利用從日本引進四個商業用芻料高粱品系（品系No.1元氣青刈、品系No.2耐病雙收、品系No.3高產、品系No.4蘇丹高粱）及選育的二個高莖高粱品系（No.5與No.6）為材料，於生育期間調查農藝性狀與產量，以評估其生產潛能，俾供日後品種選育與利用之參考。結果顯示，選育的二個高莖品系在株高、莖徑、植株鮮重、最大葉長與葉／莖比等性狀於生育初期（40天），顯著高於四個日系品系（P＜0.05）。在生育中期（75天）的農藝性狀中，選育的二個高莖品系在株高、莖徑、最大葉長、最大葉寬與植株鮮重等性狀，顯著高於日系品系（P＜0.05），於收刈割期（生育95天）之農藝性狀，選育的二個高莖品系在株高、莖徑、最大葉長、最大葉寬與植株鮮重等性狀，顯著高於日系品系（P＜0.05），顯示高莖品系在生育期間有明顯的生長勢。然葉／莖比則明顯低於日系品系（P＜0.05），將影響高莖品系的營養成分與餵飼價值。於乳黃熟收穫之牧草產量，高莖品系顯著高於日系品系（P＜0.05）。宿根栽培的產量以高莖品系最高（P＜0.05），累計全年產量以選育的高莖品系最高。由於所有參試品系均對短日照敏感（早熟），將可利用高粱幼苗（早期）的生育特性如株高、莖徑、植株鮮重與最大葉長等性狀，進行早期篩選具高產潛力的品系。

The objectives of this study were to evaluate the effects of forage sorghum agronomic characters on yield and the following ratoon croprotation. There were four forage sorghum lines introduced from Japan and two lines selected from HengChun Branch COA. LRI. as experimental materials. The results showed that the two selecting lines in traits of plant height, stem diameter, plant fresh weight, max leaf length and leaf/stem ratio in the early seedling stage (40 days), were higher than those of the four Japanese lines. Besides, both in 75 and 95 days, the traits of plant height, stem diameter, plant fresh weight, max leaf length and max leaf width of the selecting lines, were higher than those of the four Japanese lines. The two selecting lines on the growth potential fertility during the development and the yields were higher than those of introduced varieties in main production, first ratoon harvest, second ratoon harvest and total production. However, the leaf/ stem ratio of four Japanese lines was significantly higher than that of the two selecting lines. The results showed that all forage sorghum lines were sensitive to day length and the selecting lines had higher production than other four Japanese lines. It is beneficial to select the high yielding lines from the assessment of seedling agronomic characters in early stage in the basis biomass production.
