摘  要

楊紹榮、李國權、張武男.1990.檬果花器構造之探討。台南區農業改良場研究彙報24:65~72。

檬果花器在萼片及花瓣形成後,以功能雄蕊之分化及發育最早。次為退化雄蕊,雌花器之心皮發育最遲。當花穗抽出後花器之分化暨發育仍持續進行。小花綻放後調查得知:檬果花穗著生雄花、兩性花暨不完全兩性花等三種小花,以雄花最多,不完全兩性花所佔比率最少、不足1%。單一小花之功能雄蕊平均為1枚,惟凱特及懷特檬果易產生2枚或3枚之功能雄蕊;單胚型愛文及海頓檬果小花之退化雄蕊平均為4.5枚,凱特2.8枚,而多胚型本地種檬果則無明顯退化雄蕊。單一小花偶會產生2枚、3枚或4枚子房之畸形花,供試品種以愛文檬果最易發生。

關鍵詞:檬果、雄花、兩性花、花性表現。


Study of Floral Morphology of Mango (Mangifera indica)

Yang, S. R., K. C. Lee and W. N. Chang

摘  要

The order of differentiation and development of flower bud of mango were functional stamens, followed by staminodes and the carpel was the last development organ.  The differentiation of florets will be lasted after the panicle emerged.  The one of functional stamen were observed in both of cultivars of Irwin, Haden, Keitt, White and native mango, but sometimes 2 or 3 of functional stamens were produced in cvs of Keitt and White mango.  The staminodes were average 4.5 for cvs Irwin and Haden and 2.8 for Keitt mango, but there are scarcely noticeable staminodes found in native mango.  Multiple carpel (2-4) also was observed in a flower, especially in cv. Irwin.  The mango panicle consists of male, hermaphrodite and imperfect flowers.  The imperfect flowers are the least abundant (less than 1%) among the three categories of flowers.
