葡萄(Vitis vinifera L.)果皮解剖研究——细胞分裂、生长和内含物积累

An Anatomical Study of Pericarp in Grapes——Cell Division,Cell Growth and the Accumulation of Ergastic Substance

本文应用组织切片研究了葡萄子房壁细胞分裂、细胞生长和内含物积累,观察到细胞分裂率存在开花前和开花后2次高峰。测量果实外形以中横轴、中纵轴增长最大。显微测量确认中果皮、隔膜、胎座细胞的径向、切向、纵向扩张生长是果皮增厚的主要因素。组织化学测定幼果果皮含多量染色深的含内物,成熟果皮减少。并讨论了易裂果果皮的结构特征。

Using tissue section,this research studies the cell division,cell growthand the accumulation of ergastic substance in the ovary wall of grapes.It hasbeen observed that there are two high waves of cell division before and afterblossom and that the size increase is greatest at the middle cross axile andthe middle longitudinal axile.The study also reveals by microscope measurementthat the tangential,radial and longitudinal expanding growth of mesocarp anddiaphragm placenta cells are important forces of pericarp increase.The tissuechemical measurement shows that there is a lot of stainable ergastic substancein young fruit,but the same substance reduces in mature fruit.Lastly,thepaper discusses the anatomy of dehiscent fruit.
