茶壶枣果形多样性形态学观察

观察得知,茶壶枣果实形状个体之间存在着较大差异,茶壶枣的果实不同于骏枣等品种,是由子房、蜜盘、花丝残留组织共同膨大发育形成,而不是单纯由子房膨大发育形成;茶壶枣由于花芽分化不完善,花丝难以与蜜盘或子房分离,开花后花药脱落,留在蜜盘上的花丝组织残迹随蜜盘一起膨大发育而形成果实上的肉状突起。

Morphological Observation of Diversity Fruit Shape in Chahuzao Variety of Chinese Jujube

Through observation, it is known that there is great difference between the individual fruit shape of Chahuzao jujube. It was discovered that the fruit of ehahuzao jujube variety developed by the expansion of ovary, phycostemones and residual capillament organization all together rather than expansion of ovary of Junzao jujube only. In addition, the flower bud of Chahuzao jujube does not different to ripening and there＇ s adhesion between some capillaments and phyeostemones. When the Chahuzao jujube flowers, some eapillaments can＇ t outspread and then residual eapillament expands and develop to protuberance on fruit.
