摘要

本試驗主要探討於黏重土壤下作畦及不作畦栽培模式對洋桔梗生育及切花品質之影響。不同栽培模式下，品種間除了節間長及花梗長度外，在所有的切花品質性狀上都有顯著性差異存在，其中莖徑以白金紫4.3 mm最粗其次為羅莎綠4.1 mm及羅莎粉3.6mm，其餘性狀皆以白金紫表現最佳。另一方面作畦及不作畦處理中在生長與發育性狀上除切花莖徑、葉幅寬有明顯差異存在外，其餘性狀並無明顯差異存在，其中不作畦莖徑為3.8mm、作畦4.2mm，顯示在黏重土壤種植洋桔梗，作畦栽培可以明顯提高莖徑。而在開花品質性狀上除花朵數，無明顯差異存在外，其餘性狀包括第一朵花高、花苞數、花徑、花梗長度、盛花期及地上部鮮重，都有明顯差異存在。在花梗長度上，不作畦12.4 cm、作畦10.8 cm，顯示作畦對洋桔梗生育中後期水分管理較容易，而使花梗抑制的效果較佳，同樣情況也表現在地上部鮮重性狀上，作畦49.3 g比不作畦43.5 g明顯較重。

Study on bedding of growth and development of Eustoma cultivars under clay soil. Different cultivars, have significant different in all results except, nodes length and flower stalk. ”Platinum” is the best which stem diameter is 4.3 mm ”Rosa Green” is 4.1 mm and ”Rosa Pink Fresh” is 3.6mm. Ridging or nonridging growing except that there are obvious differences to exist in stem diameter and leaf width on the other characters have no significant different. It is stem diameter ridging have 4.2mm, non- ridging 3.8mm, show that is clay soil and planting the Eustoma, bedding culture can obviously improve the stem diameter. Except that the flowering quality, obvious difference to exist in flower numbers, other properties including first flower high, bud numbers, flower diameter, flower stalk, flowering time and fresh weight, obvious have significant different. Flower stalk length, make ridging of 12.4cm, non- ridging 10.8cm, show planting middle and later periods to be moisture management easy flower stalk it suppresses to be relatively apt result of up toing to Eustoma, same situation department at the fresh weight, ridging of 43.5 g, non- ridging 49.3 g there is the same situation.
