Abstract

In this paper, the physical and chemical differences of seed coat between hard and soft seeds from the same Licorice lot were identified. Electron microscopy-based examination revealed that the cracks on hard seeds coat were much less obvious (shallower and narrower) than those of soft seeds, and that hilar fissure from hard seeds was considerably narrower. Endosperm of hard seeds was markedly thicker than that of soft seeds. Finally, X-ray fluorescence spectrometry revealed significant enrichment for 12 out of the 14 tested mineral elements in hard seed coat. It could be concluded that these above features of hard seeds would increase their resistance to physical impact and protect against cracks in seed coat surface, thus contributing to the impermeability of hard seeds.

甘草硬、软种子种皮的理化差异
本文对同一批次甘草硬种子和软种子种皮的理化差异进行了鉴定。电镜检查发现,硬种子皮上的裂纹比软种子皮上的裂纹要浅得多,窄得多,而硬种子皮上的门裂要窄得多。硬种子胚乳明显厚于软种子胚乳。最后,x射线荧光光谱分析显示,在硬种皮中,14种矿物元素中有12种元素显著富集。由此可见,硬种子的这些特性增加了其抗物理冲击的能力,并防止种皮表面出现裂纹,从而提高了硬种子的抗渗性。
