Microscopic examination of sectioned cone stalks failed to reveal an abscission layer in loblolly or slash pine. Near the angular crotch of stem and stalk is an area of weakness resulting from an indentation in the stalk's cortex. Another possible reason for the ease of cone detachment is a greater volume of xylary rays in stalks than in vegetative stems. Forest Sci. 20:41-46.
