AN INVESTIGATION OF THE INTERFERENCE COLOURS TRANSMITTED BY MATURE AND IMMATURE COTTON FIBRE UNDER POLARISED LIGHT MICROSCOPY

摘要

A study of interference colors transmitted under crossed polars by mature and immature cotton fibers has shown that the yellow hue of the ‘mature’ interference color is the same between cotton plant species and appears to be dependent upon relativefiber wall thickening. That the interference colors appear to be independent of crosssectional wall area and perimeter and dependent upon relative fiber wall thickening, suggests that a case can be made to automate the standard test method for measuringcotton fiber maturity utilizing polarized light microscopy. Such a test would enable a quick and accurate direct measurement of cotton fiber maturity.
