Abstract
The botanical nature of bark constituents in raw cotton, and the anatomical properties of field plants at harvest time were studied. The quantity of bark present was determined by direct removal and weighing. Botanical determinations were made by sampling segments from the main stem, fruiting branch, and pedicel of the cotton plant and examining them by transmission light microscopy. Testing for bark presence was done at several different phases of cotton processing and the percent weight of barklike strands was determined by examination of visible wastes from the Shirley analyzer. These unstained strands were then examined microscopically. Anatomical studies indicated that the majority of barklike strands from bur and raw cottons were phloem fiber groups. A positive association between high levels of stick material in bur cotton and bark in raw cotton was verified. The authors suggest that a quantitative procedure for estimating bark content might be useful for those raw cottons that are used in open end spinning.
