豆科在牧草中占有很重要的地位。根据种子,把种或变种大致区别开对生产是有益的。区别豆科种子的方法很多,如荧光法、化学法、薄层色谱法、幼苗法等。本文仅限于根据种子形态来鉴别,在这方面Musil,对种子胚根与子叶的关系(即胚根尖与子叶分开与否和胚根长与子叶长之比例关系)作了研究,而Gunn则侧重于研究种脐、种瘤和脐条三者间的相对位置,以及种脐长度与种子 Leguminosae in the forage occupies a very important position. Depending on the seed, it is beneficial to make a broad distinction between species or varieties for production. There are many ways to distinguish leguminous seeds, such as fluorescence, chemical, thin layer chromatography, seedling and so on. In this article, Musil identified the relationship between seed radicle and cotyledon (ie, the separation of radicle tip from cotyledon and the ratio of radicle root length to cotyledon length), while Gunn Focus on the study of umbilical, tumor and umbilical cord between the relative position of the three, as well as umbilical cord length and seed
