Calcium oxalate crystals are a major biomineralization product in higher plants. Their biological function and use are not well understood. In this work, we focus on the isolation and crystallochemical characterization of calcium oxalate crystals from seed coats of Phaseolus vulgaris (prisms) and leaves of Vitis vinifera (raphides and druses) using ultrastructural methods. A proposal based on crystal growth theory was used for explaining the existence of different morphologies shown by these crystals grown inside specialized cells in plants.
草酸钙晶体是高等植物中主要的生物矿化产物。它们的生物学功能和用途尚未得到充分了解。在这项工作中，我们利用超微结构方法，专注于从菜豆种皮（棱柱体）和葡萄叶片（针晶体和晶簇）中分离草酸钙晶体并进行晶体化学表征。基于晶体生长理论提出了一个方案，用于解释植物中特化细胞内生长的这些晶体所呈现出的不同形态的存在原因。
