本文介绍了正常的葡萄浆果和不同的射击葡萄浆果在第一个生长期（受精后的第一个月）的组织结构。我们将观察集中在受精过程中的4个特定区域，即葡萄浆果的隔膜，用不同的组织化学试剂处理以选择性地显示酚类化合物和某些组织;每个样品都通过可见光和紫外光进行检查。对照葡萄浆果的隔膜始终是纤维素的，而射击葡萄浆果的隔膜具有典型的伤口反应的木质化（疤痕）组织，并且与正常葡萄浆果中未观察到的类黄酮色素的显着积累相关。这种韧带组织的起源进行了讨论。
This paper describes the histological structure of normal grape berries and of different shot grape berries during the first growth period (the first month after fertilisation). We focused our observations on 4 specific zone during fertilisation, i.e. the septum of the grape berries, which was treated with different histochemical reagents to selectively reveal phenolic compounds and certain tissues; each sample was examined by visible and ultraviolet light. The septum of control grape berries was always cellulosic, whereas the septum of shot grape berries featured lignified (scar) tissue typical of a wound reaction and associated with significant accumulation of flavonoid pigments not seen in normal grape berries. The origins of this lignified tissue are discussed.
