The Effect of Length of Day on the Height Growth of Certain Forest Tree Seedlings
Abstract:Although considerable experimental work has been done on the effect of length of day on the growth, flowering, and fruiting of agricultural and horticultural plants, comparatively little work has been done on the effect of length of day on forest trees. The results reported here of work done at Duke University have important technical implications. For instance, they show that slash pine, shortleaf pine, jack pine, and beech can be thrown out of their normal growing rhythm by long days; but the normal period of growth of other species such as chestnut oak and southern red oak is not readily changed.
