‘巨峰’葡萄變異株之園藝性狀及果實發育

Abstract

本研究調查一'巨峰'葡萄變異株之園藝性狀與果實發育，並以'巨峰'品種作為對照。結果顯示，變異株之枝條及葉片型態與'巨峰'並無明顯差異，主要差異在於花及果實。變異株之花器及果形均較細長，子房內支胎座及胚珠數目異常比率高，多形成無子的橢圓形果。變異株之果實較'巨峰'小，且成熟期較'巨峰'早。There was no apparent difference in shoots and leaves between 'Kyoho' and 'Kyoho' mutant. The major morphological variations were the flower and berry shapes; those of the mutant were more elongate. Most ovaries of the mutant had abnormal placetae and ovules, which led to an abnormal unsymmetrical shape. Berries of the mutant were smaller and ripened earlier than 'Kyoho'
