| Abstract | ||
| The present study aims to describe and characterize the The present study aims to describe and characterize the morphology of the embryo and the seedling; including the cotyledonary, the first unifoliate and first trifoliate foliage leaves and their importance in the taxonomy of the studied Trifolium species. Macromorphological (cotyledon, seedling with first unifoliate leaves and first trifoliate leaves) studies carried on 15 Trifolium species. Qualitative and quantitative characteristics of the embryo, seedling with cotyledonary, seedling with first unifoliate and second trifoliate leaves indicated that cotyledon characters (cotyledon shape; L/W ratio, apex, colour, radicle position; shape, apex), cotyledonary leaves (hypocotyl colour, blade shape, L/W ratio), first and second leaves (shape, apex base, margin and texture). Numerical analysis is carried and also phenogram illustrating the relationship between the studied taxa were constructed by calculating the average taxonomic distance. Results have a taxonomic significance in identification and differentiation between the studied 15 Trifolium species. An identification key was prepared. | ||
