Abstract
A method of detecting environmental stress in plants, particular water stress in cotton plants is based on a hot dilute acid extraction of plant tissues such as cotton fibers. The extracts are analyzed by high pH anion exchange chromatography to separate and characterize the carbohydrates. This method extracts a characteristic series of carbohydrate multimers containing galactose, mannose and glucose. The pattern of multimers is indicative of growth stress during the formation of the plant tissue. In addition, similar multimers can be extracted from textiles and are indicative of textile wear and can be used to determine which manufacturing treatment will improve fabric life.
