摘　　要：扁桃(Amygdalus cummunis L.)的食用部位为种子。试验以扁桃种皮为材料,通过半薄切片和透射电镜,观察了扁桃种皮发育过程早、中、晚3个时期的组织结构和超微结构变化,对其维管束结构观察,发现维管束SE/CC复合体与周围韧皮薄壁细胞的胞间连丝发达,初步推断扁桃种皮以共质体方式进行糖卸载,同时对扁桃种皮细胞衰老方式进行了探讨。The ediblepart of almond is its seed.The tissue structure and ultrastructure of the almond seed capsule were observed and the phloem structure of the almond seed capsule at the early,middle and late developmental stages were studied by light microscopy and transmission electron microscopy.The results showed that vascular bundle structure of SE/CC comlex and the surrounding phloem parenchyma cells were well developed.It was speculated that the almond seed capsule may be the main symplastic pathway of the photoassimilates unloading.The cell senescence of the almond seed capsule was analysed.
