Increasing seed weight resulted in increased seedling dry weight and increased leaf area but did not affect the relative growth rate of Vicia dasycarpa . Varying the depth of planting did not significantly affect seedling dry weight or leaf area during time intervals measured from emergence. The inference was drawn that cotyledonary reserves do not have a major influence on the size of the photosynthetic organs of this hypogeal species. Since these results are similar to those reported by others for epigeal legumes, it is suggested that the positioning of the cotyledons in either the aerial or the subterranean enviroment has no marked effect on the growth in dry weight or leaf area of forage legumes.
