Variation of Sweetgum Fiber Length Within and Between Upland and Bottomland Sites

sweetgum, fiber length, upland, bottomland


A total of 79,550 fibers were measured from sample trees representing upland and bottomland sites in Louisiana. These sites represent three separate geographic areas within the state. In all sample years, average fiber length was significantly longer in trees from upland sites in Area 2, significantly shorter in trees from upland sites in Area 3, with sites in Area 1 being significantly different in only two sample years. Thus the magnitude and nature of variation between upland and bottomland sites appear to be geographically isolated.
