The microhardness of individual morphological structures of the hard coat of the seed of Gleditsia triacanthos L. was measured. Measurements were made on the transverse and frontal planes. Based on the differences in the hardness of the two planes, the anisotropy of the seed coat was revealed. The entire seed coat has a special hardness which can be compared with the hardness of hardwood like oat wood. An interesting feature was the hardness of the endosperm, comparable to the hardness of the epidermis. Further study of the processes that occur in seeds during imbibition is based on the obtained data. Mathematical modeling methods are the most promising for these tasks; they will help to identify the points of fragility and the points of the greatest tension in the seed coat. These results will allow us to find the best ways to destroy the seed coat and to accelerate the germination. Research of physical properties of the seed coat is of practical importance in the fact that in the future it will allow reducing of the hard-seeding and increasing the germination of seeds. The obtained data allows us to represent the initial hardness of the seed coat.
测量了皂荚种子硬壳的各个形态结构的显微硬度。在横切面和正面进行了测量。基于两个平面硬度的差异，揭示了种皮的各向异性。整个种皮具有特殊的硬度，可以与像燕麦木这样的硬木的硬度相媲美。一个有趣的特点是胚乳的硬度，可与表皮的硬度相媲美。进一步研究种子在吸水过程中发生的过程是基于所获得的数据。对于这些任务，数学建模方法是最有前途的；它们将有助于确定种皮中脆弱点和最大张力点。这些结果将使我们能够找到破坏种皮并加速发芽的最佳方法。研究种皮的物理性质具有实际意义，因为未来它将允许减少硬籽并提高种子的发芽率。获得的数据使我们能够表示种皮的初始硬度。
