    郁南无核黄皮胚囊异常发育的细胞学观察

    The Cytological Observation of Embryo Sac Development Abnormality in Yu''nan Seedless Wampee

    • 摘要: 利用石蜡切片观察了郁南无核黄皮和有核鸡心黄皮胚囊发育状况. 结果表明:郁南无核黄皮胚囊发育存在败育现象,即表现为开花当日有91.9%的胚囊未发育达到受精的成熟状态,花后1~7 d,仍有81.6%的胚囊未发育达到八核期成熟胚囊;而对照材料有核鸡心黄皮在开花当日和花后7 d内发育到八核期成熟胚囊的比率分别为96.7%和100%. 郁南无核黄皮胚囊受精前败育是导致其无核的重要原因之一,也是其和有核黄皮混种能稳定保持无核性状的重要原因.
