Stalks of Makiling Puti abaca cultivar at pre-flagleaf stage of development were stored at various periods of time, namely; 0 (control), 10, 20, 30, 40, 50 and 60 days to determine the changes in chemical characteristics of the fiber during storage. Fiber tensile strength and alphacellulose content were significantly increased when stalks were stored up to 30 days. Regardless of storage duration, on the other hand, fiber extracted from the inner leafsheaths had significantly the lowest value for these parameters. Significant interaction effects between storage duration and leafsheaths position were observed for the mean percentage fiber recovery, holocellulose and crude fat contents of abaca fiber. Prolonged storage of stalks (60 days) did significantly impair fiber quality of the outer leafsheaths particularly its holocellulose content
