中文摘要 | 本試驗採45與95度角之4m垂直高架遮蔭物,探討離遮蔭物不同距離甜椒生育及植 株光合能力表現。試驗結果顯示,垂直高架遮蔭物,對臨近植株隨遮蔭時數增加及日射量減 少,造成甜椒光量密度大幅減少。甜椒葉片葉肉傳導度與水分利用率,皆因遮蔭效果而明顯 下降,植株羧化效率減少,淨光合成速率降低,因此採收甜椒植株高度、地上部鮮重、地下 部鮮重及果粒鮮重均減少。 |
英文摘要 | This study was designed to evaluate the effect of 4m height of 45 and 95 angles vertical shading on the growth and photosynthesis of fall sweet pepper. The result was indicated that vertical shading increased shading duration, and decreased solar radiation, and subsequently decreased photosynthetic photon flux density. Vertical shading also decreased mesophyll conductance and water use efficiency of sweet pepper, therefore, carboxylation efficiency was lower, the net photosynthesis rate decreased and subsequently reduced plant height, shoot fresh weight, root fresh weight and fresh weight per fruit of sweet pepper. |
