摘要: 為瞭解巨峰及蜜紅葡萄在一年兩收生產模式下之主芽壞死狀況,觀察其不同生長勢結果枝或結果母枝第4~11節之8個主芽壞死數、橫切面組織及主芽生理活力。結果顯示,巨峰葡萄結果枝滿花後110日之主芽壞死發生以強生長勢枝梢之1.3個4(16.8%)為最多,中生長勢枝梢次之為0.34個(43%),弱生長勢枝梢者無主芽壞死。此結果枝至翌春之間主芽有繼續壞死之現象,其中強生長勢枝梢之壞死數(率)增加為4.2個(52.5%),中生長勢枝梢增加為2.45個(30.6%)及弱生勢枝梢者增加為1.15個(14.4%),而結果母枝4~7節位之主芽壞死較8~11節位者多。由結果母枝橫切面之顯微觀察發現發生長勢枝梢之髓部及導管較大、亦有較多的導管數。結果枝主芽之生理活力則以中生長勢枝梢者最高,強生長勢枝梢則最低,其中4~7節位之主芽活力較8~11節位者低,而活力較低者其隔年主芽壞死數較多。至於蜜紅品種則與巨峰有相似的拮果,但主芽壞死情況未若巨峰嚴重。
Primary bud necrosis of 'Kyoho' and 'Honey Red' grapevines under one year two crops condition were investigated. The number of primary bud(4-11 th nodes) necrosis, transverse section of stem tissue and primary bud tissue viabilities were examined. The results showed that strong vigorous canes of 'Kyoho' grapevine had 4.2 (52.5%) necrotic buds and weak vigorous canes had only 1.15 (14.4%) buds.The primary bud necrosis number at budbreak was higher than that at 110 days after full bloom in the previous season, and 'Honey Red' had lower necrotic buds than 'Kyoho' . The basal 4~7 nodes bore higher number of necrotic primary bud than 8~11 nodes. Strong vigorous canes had higher vessel number, longer vessel diameter and pith diameter. Primary buds of normal vigorous shoot had higher viability, based on TTC (2,3,5- triphenyltertrazolium chloride) assay, than those of strong vigorous shoot. The strong vigorous shoot, which had the lowest primary bud viability, bore the highest number of necrotic primary bud.
