矮牵牛花粉含有非常大量的植酸（2.1重量%），其占花粉粒的总磷含量的37%。在一项广泛的植物调查中，所有花柱长度为5 mm或更长的物种都有显著的（0.05-2.1%重量）花粉植酸含量。这些植物包括核桃、黄连木、金鱼草、百合和鹤望兰。相比之下，复合材料和草（玉米除外）测试有非常短的风格和没有检测到的植酸花粉。有人建议，植酸是参与提供前体细胞壁合成所需的快速花粉管伸长授粉植物的风格。
Petunia hybrida pollen contained a very large amount of phytic acid (2.1% by weight) which comprised 37% of the total phosphorus content of the pollen grain. In a survey of a wide range of plants, all species with a style length of 5 mm or more had a significant (0.05-2.1% by weight) pollen content of phytic acid. These included Juglans regia, Pistacia chinensis, Antirrhinum majus, Lilium henryi and Strelitzia reginae. In contrast the composites and grasses (except for maize) tested had very short styles and no detectable phytic acid in pollen. It is suggested that phytic acid is involved in providing precursors for cell-wall synthesis necessary for rapid pollen tube elongation down the styles of pollinated plants.
