核桃果皮的组织解剖学研究

Study on the tissue anatomy on the pericarp of Juglans Regia L

  • 摘要: 研究表明核桃果皮(果壳)结构可分为外、中、内果皮3层,其发育阶段可分为前后2个时期。外果皮由数层细胞组成,前期表皮细胞密布腺毛,后期发育出角质层和气孔构造。不同品种及果实不同部位间果点亦有差异。中果皮为果肉的大部分,细胞大,中间散生有多束维管束。前期3层果皮界限不明显,进入后期后维管束数目增加,类型增多且出现分叉。前期内果皮细胞小而透明,与中果皮界限不明显,后期则迅速木质化而形成硬壳,逐渐转化为坚硬的木质化石细胞层,其外的维管束组织高度发达呈网络状。

     

    Abstract: The tissue structure of the pericarp of Juglans regia L.may be divided into three parts,i.e.exocarp,mesocarp and endocarp.The development stage can be divided into the early stage and late stage.The exocarp is consisted of lays of cells.There are numerous glandular hairs in the epiderm cells in the early stage and the corneous layer cells and stomata are developed in the late stage.The spots in fruit surface are different in the different varieties and positions of fruit.The mesocarp is the main parts of pericarp,and there are vascular bundles in it.The boundary lines between exocarp,mesocarp and ndocarp are not clear in the early stage,but the numbers of vascular bundles increase and the branches appear,as well as the parenchyma cells are enlarged in the late stage.The cells of endocarp is small and transparent in early stage,and changes into hard shell that is made of lignification stone cells.The tissue of vascular bundles is developed and becomes ereticulate vein.
