扁桃是重要的干果。本试验以扁桃果实为材料,通过半薄切片法和透射电镜法处理,观察了扁桃果实早、中、晚3个时期各层组织结构和超微结构发育变化。同时观察了扁桃果实维管束结构,发现SE/CC复合体与周围韧皮薄壁细胞没有胞间连丝,属于共质体隔离,初步推断扁桃果实以质外体卸载方式为主。 Almond is an important dried fruit. In this experiment, almonds were used as materials to investigate the histological and ultrastructural changes of Almonds in three stages of early, middle and late stages of almond by semi-thin sectioning and transmission electron microscopy. At the same time, we observed the vascular bundle structure of Almond and found that the SE / CC complex and the surrounding phloem parenchyma cells had no interstitial filaments, which belonged to the isolation of the common plastids. It was preliminarily concluded that the apricot fruit was mainly unloaded by the apoplast.
