Morphological Differentiation of Flower buds in Sweet Pepper

Abstract

甜椒花芽分化以銘星品種而言，二片本葉苗齡時，已具花芽原始體，藍星品種則需至三片本葉始達此階段，在藍星品種切片試驗觀察中，可見花萼形成期所需時間較長。花芽原始體出現後，莖頂開始增寬成圓頂狀，在芽體兩側依序發生，形成花萼，其後花瓣，隨後雄蕊及雌蕊心皮的分化，完成花芽之分化。Flower bud differentiation of pepper had shown cultivar Andalus flower primoduim at 2 leaf stage while cultivar Blue Star was observed at 3 leaf stage. In paraffin section observation of Blue Star required longer time for the development of calyx. After the appearance of flower primoduim, the shoot apex changed to dome shape and beginning the formation of petal, sepal followed by stamen and pistal and then completion of the flower initiation
