葡萄植株光合産物運移之研究 (Ⅰ)不同誘引方式下葡萄植株中光合産物的運移模式

Translocation of Photosynthates in the Concord Grape (Ⅰ) Translocation Pattern of Photosynthate in Grapevines with Different Training System

摘要


葡萄扦挿幼株,留是一技條培育,不同植株分別行水平或垂直誘引,以碳14標識的蔗糖處理枝條中段生長約30天的單一藥片時,處理藥片向外輸出的含碳化合物,除了向下運送到根部外,同時也運移於其他枝條及藥片中;行水平誘引時,由處理藥片運移出來的含碳化合物,大部分蓄積在上段枝條部位,而垂直誘引者,碳化合物有被向上、向下雙向等量運移的情形。另外,將葡萄幼株留二枝條培育,其中之一行水平誘引,另一枝條行垂直誘引,生長三個月後,以碳14標識的蔗糖分別處理於垂直或水平枝條中段的藥片時,垂直枝條中段及水平枝條中段的藥片,主要將含碳化合物運移根部眝積;而垂直枝條中段的藥片級同時對水平及垂直二枝條運送等比例的含碳化合物,但水平枝條中段的藥片,則將大部分的含碳化合物轉運於其着生的枝條中。

The purpose of this investigation is to try to realize the mode of translocation of photosynthates in Concord grape by using 14C-labelled sucrose as tracer. When vines with single shoot were vertically or horizontally trained, a 30-day-old leaf on the midsection of shoot was treated with 14C-sucrose. Both the leaf on the vertical shoot or horizontal shoot translocate the 14C-compounds into leaves and mainly into the roots. Nevertheless, when horizontally trained, the 14C-compounds were mostly accumulated in upper portion of the transporting leaf. When vertically trained, the 14C-compounds were equally translocated to the upper and lower portion of the shoot. Grapevines with two shoots, one was vertically trained and the other was horizontally trained, a 25-day-old leaf on the midsection of the vertical shoot or the horizontal shoot was treated with 14C-sucrose. Both the leaf transport the 14C-compounds basipetally to the roots, Nevertheless, the leaf on the vertical shoot also transport equal amount f 14C-compounds into the horizontal shoot and the vertical shoot, and the one on the horizontal shoot transport 14C-compounds mainly within the lateral shoot.
