【摘要】 以南方观赏桃花的花芽为材料,通过植物冰冻切片的方法系统地对花芽分化进行切片观察,以得到"茶中红"花芽在分化时期的形态变化图像。结果显示:桃花花芽分化时期主要集中于9月中下旬至12月上旬,历时大约2个多月。茶中红桃花花芽形态分化主要分为未分化时期,花芽分化初期,萼片分化期,花瓣分化期,雄蕊分化期,雌蕊分化期六个时期。分化初期共37 d,花萼分化期共21 d,花瓣的形成期共20 d,雄蕊分化期7 d,雌蕊在12月1号之后全部形成。更多还原

【Abstract】 Take flower buds of South China ornamental peach blossom as researd object, observe plant frozen section biopsy of Tea Red peach flower bud differentiation systematically to collect the morphological change images in flower bud differentiation period. The results show that bud differentiation period of peach blossom mainly concentrated from mid- to- late September to early December, which lasted about 2 months. Tea Red peach flower bud morphological differentiation period mainly divided into six stages, they were undifferentiated stage, flower bud differentiation initial stage, sepal differentiation stage, petal differentiation stage, stamen differentiation stage and pistil differentiation stage. Differentiation initial stage lasted for 37 days, sepal differentiation stage lasted for 21 days, petals forming period needed for 20 days, stamen differentiation stage 7days, pistil all formed after December1.更多还原
