Abstract
A method of detecting environmental stress in plants, particularly water stress in cotton plants is based on a cold water extraction of plant tissues such as cotton fibers. The extract is analyzed by high pH anion exchange chromatography to separate and characterize the saccharides, oligosaccharides and other glycoconjugates extracted by cold water. The extracted carbohydrates represent a uniquely sensitive means to detect environmental stress. Environmentally stressed plants show both a qualitative and quantitative alteration of the extracted carbohydrates. The alteration in extracted carbohydrates can be used to indicate when additional irrigation or other correction to the growth conditions is required.
