| 中文摘要 | 夏季高溫易使洋桔梗植株提早由營養生長階段轉為生殖生長階段,使莖長度不足而降低切花品質,為避免因溫度熱累積造成植物不良現象,本研究探討不同遮光網處理對春、夏季洋桔梗生育及切花品質之影響。洋桔梗'Korezo Light Pink'可柔亮粉於一次切花後,側芽長出30~40 cm時留側芽1枝開始遮光,分別使用50%黑色遮光網、50%銀色遮光網及70%紅色遮光網,至切花採收共遮光11週,遮光網高度為地面上算起2.3 m。結果顯示70%紅色遮光網的表現效果較50%黑色遮光網、銀色遮光網及對照組為佳,相較50%黑色遮光網、銀色遮光網,除分別提高株高6.6 cm及2.0 cm、增加葉綠素值SPAD 4.6及2.6、增加單枝鮮重9.0 g及4.6 g、著花節位高度增加7.5 cm及3.9 cm、紅色度增加3.12及2.52、增加總花數3.5朵及2朵等較優的園藝特性外,瓶插壽命亦可分別延長1.1天及0.5天,本試驗結果可提供農民栽培參考。 |
| 英文摘要 | Eustoma grandiflorum is flowering rapidly in summer that plant height is short and the quality of cut flower is poor. In order to reduce the adverse influence of high temperature in summer, the effects of different shading net on re-bolting shoots of Eustoma grandiflorum 'Korezo Light Pink' were investigated. The shading period was 11 weeks, and the shading treatments were 50% black shading net, 50% silver shading net and 70% red shading net which are 2.3m height above the field. Compared with black and silver shading net, the 70% red shading net showed better effects of plant height, chlorophyll contents, total flower number, and vase life. The plant height of Eustoma grandiflorum in red shading net was 2~6.6 cm higher than the other treatments. SPAD value increased 2.6~4.6, fresh weight increased 4.6~9.0 g and totoal flower number was 2~3.5 more. The red chroma of cut flowers treated with red shading net treatment was also higher than other treatments. |
