中文摘要 | 本試驗以「Sunbright supreme」及「Sunrich orange」兩品種為供試材料,分別以35×35cm、20×20cm、15×15cm及12×12cm四種栽植行株距為處理,探討不同栽植密度對切花用向日葵生育之影響。結果顯示,兩品種之株高及葉片數,處理間差異均未連顯著顯著水準,而葉長及葉寬隨行株距增加而增加。切花品質方面,「Sunbright supreme」品種之頭狀花徑、管狀花徑、舌狀花長、花瓣數、花頸直徑、花梗直徑及切花的乾鮮重,均隔行株距增加而增加,且處理間差異達顯著水準;而「Sunrich orange」品種除頭狀花徑,佳狀以種植在行株距35×35cm處理與其他處理有顯著差異外,其餘各性狀調查結果與「Sunbright supreme」品種相同。 |
英文摘要 | The experiment was conducted to study the effects of four planting densities (ie. 35×35 cm, 20×20 cm, 15×15 cm and 12×12 cm) on two sunflower (Helianthus annuus L.) cultivars "Sunbright supreme" and “Sunrich orange". No influence of plant density on the plant height and the number of leaf were obtained, but the width and length of leaf were increased as planting density enlarged. The flower head diameter, diskfloret diameter, rayfloret length, rayfloret width, number of sepal, stem neck diameter, stem diameter, the fresh and dry weight of cutting flower of Sunbright supreme were greater at lower planting density. Similarities for the cut flower quality characters were observed on Sunrich orange, except for the 35×35 cm treatment. |
