中文摘要 | 為瞭解棚架型式對巨峰葡萄生長與光合成速率之影響,本試驗以巨峰 葡萄在水平棚架(Horizontal)、高垣籬雙幹式(Duplex-UMB)、低垣籬雙幹式(Duplex -FEN)、垣籬單幹式(Vertical-FEN)及豆籬式(3H-V-shaped)等五種棚架下栽培,於 萌芽後新梢開始生長至果實成熟期間調查植株生長情形,並在果實發育之不同階 段調查花穗對面葉片之光合成速率,果實成熟期調查結果枝上不同節位葉片之光 合成速率。結果發現棚架型式影響枝條生長,開花期以水平棚架及高垣籬雙幹式 之枝條長度較長,垣籬單幹式及豆籬式枝條長度較短;開花後70天及果實成熟 期以水平棚架及豆籬式枝條轉變為木質化之百分比較高,高垣籬雙幹式及低垣籬 雙幹式轉變為木質化比例較低,但高垣籬雙幹式及豆籬式枝條木質化長度較短, 且豆籬式枝條直徑最細。在果實發育不同階段調查花穗對面葉片光合成速率,在 開花後30天葉片光合成速率最高,果實成熟期葉片光合成速率都降至52%以下 ;在不同葉位之調查顯示葉齡影響光合作用能力,枝條基部之葉片光合成能力下 降,在第一花穗後第6及10片葉光合成速率較高。 |
英文摘要 | In order to clarify the effect of trellis systems on growth and photosynthetic rate of "Kyoho" grapevine (Vitis vinifera L. X Vitis labruscana Bailey CV. Kyoho), five trellis systems, Horizontal; Duplex- UMB; Duplex- FEN; Vertical-FEN and 3H- V- shaped were used in the experimental field of Taichung DAIS. Vine growth and leaf photosynthetic rate were investigated from blooming stage to fruit mature stage. The results indicated that shoot growth was affected by trellis system. Shoot length was longer in both Horizontal and Duplex-UMB systems but shorter in Vertical -FEN and 3H-V-shaped systems at blooming stage. The percentage of lignified shoot was higher in Horizontal and 3H-V-shaped, but lower in Duplex-UMB and Duplex- FEN systems. The length of lignified shoot in Duplex-UMB and 3H-V-shaped systems was shorter. Shoot diameter appeared to be slender in 3H-V-shaped system. Photosynthetic rate of leaves opposite to the first cluster was measured at different stages of berry development and different positions of shoot at fruit mature stage. Photosynthetic rate reached the maximum at 30 days after blooming, then decreased more than 48% at fruit mature stage. Photosynthetic rate was affected by leaf age. Apparently, photosynthetic rate declined in the leaves at shoot basal. However, higher photosynthetic rate was found at the 6-10th leaves after first cluster at fruit mature stage. |
