1.中国水仙每个3年生鳞茎约有花序3～7枝;3～11朵花组成一伞形花序。花各部分轮状排列。 2.中国水仙花芽分化可分为8个时期:叶芽期、花序原基形成期、佛焰状总苞形成期、花原基形成期、花被形成期、雄蕊形成期、雌蕊形成期和副花冠形成期。 在漳州地区,中国水仙花芽分化开始于7月上旬,7月中旬佛焰状总苞原基出现,7月下旬花原基出现。在第一朵花中,外轮花被原基出现于8月上旬,8月中旬内轮花被原基出现,8月中旬末至下旬中期外轮雄蕊原基出现,8月下旬内轮雄蕊原基出现,9月上旬心皮原基出现,9月中旬胚珠原基出现于中轴中部,9月下旬副花冠原基出现。小孢子母细胞减数分裂发生于11月中旬,大孢子母细胞减数分裂发生于10月中旬。同一花序中,每1朵花各部分的分化都较前1朵花同一部分的分化推迟约1个发生期。
1. Chinese Narcissus Each 3-year-old bulbs about 3 to 7 inflorescences; 3 to 11 flowers composed of a umbel. Flower arrangement of all parts of the wheel. 2. Narcissus bud differentiation can be divided into eight periods: leaf bud stage, the formation of inflorescence primordium, the bud-shaped bud formation, the primordium formation period, the formation of the period, the formation of stamens, pistil formation and vice Corolla formation period. In Zhangzhou, the Chinese narcissus flower bud differentiation started in early July, and in July the bud of the bud-shaped primordial bud appeared, and the flower primrose appeared in late July. In the first flower, the outer flower primordia appeared in early August, mid-August within the flower primordia, mid-late August to late mid-stamens primordia appear, in late August the inner stamen primordia Appeared in early September carpels primordial found in mid-September ovule primordium in the central axis, coronal primordium in late September appeared. Microspore mother cell meiosis occurred in mid-November, megaspore mother cell meiosis occurred in mid-October. In the same inflorescence, the differentiation of each part of each flower is delayed by about 1 occurrence compared with the differentiation of the same part of the previous flower.
