Abstract
Fifteen Acer species were examined to study distribution and percentage by area of their libriform fibers. Safranin-O and astra blue dissolved in alcohol solution is an effective differential staining method to identify and localize libriform fibers. They have larger lumens than fiber tracheids, intercellular spaces, and occur in various patterns, ranging from large groups to wavy bands. In some cases they occur in radial files. The percentage by area of libriform fibers ranges from 14 to 40%. Inconspicuous to moderately visible spiral thickenings are part of the Acer libriform fibers and fiber tracheids. Differences in stain reactions and fluorescence indicate that libriform fibers differ in lignin concentration or composition from fiber tracheids – the concentration of syringyl lignin is greater in libriform fibers.
