为了解极早熟品种骆驼黄杏花芽分化时期与分化特点 ,于 1998～ 1999年以河北省易县独乐乡中独乐村 6a生骆驼黄杏为试材 ,采用石蜡切片法对其花芽分化进行了系统的观察研究。结果表明 :骆驼黄杏花芽分化自 6月下旬开始至 9月底结束 ,分化盛期集中在 7～ 9月份 ,其分化过程分为未分化期、分化初期 ,萼片分化期、花瓣分化期、雄蕊分化期、雌蕊分化期等 6个时期 ,需要 90多d。雌蕊分化后表现出多种畸变形式 ,主要有花柱萎缩、弯曲、长于雄蕊等 ,这一现象的出现除与品种特性有关外 ,还与营养状况、栽培技术密切相关
In order to understand the differentiation and differentiation characteristics of camel’s yellow apricot flower buds during the period of 1998 ~ 1999, Huang camel yellow apricot (Camellia oleracea) from Zhonglu Lok village in Dile Township, Yixian County, Hebei province was used as material to conduct flower bud differentiation by paraffin section The system of observation and research. The results showed that the flower buds of camel’s yellow apricot began to differentiate from the end of June to the end of September, with the peak of differentiation concentrated from July to September. The differentiation process was divided into undifferentiated stage, early stage of differentiation, sepal differentiation stage, petal differentiation stage, Period, pistil differentiation and other six periods, need more than 90 d. Pistil differentiation showed a variety of forms of distortion, the main styles of atrophy, bending, longer than the stamens, in addition to the appearance of this phenomenon with the variety characteristics, but also with nutritional status, cultivation techniques are closely related
