05: Carbohydrate status as a measure of seedling quality


Seedlings depend on reserve carbohydrates from the time they are lifted until photosynthesis is sufficient to meet the demands of growth and respiration. If carbohydrate reserves are inadequate to meet respiratory demands associated with cold storage and outplanting, the seedling will die. If carbohydrates are stored as starch, the relative amount can be estimated by the degree to which iodine stains a cross section of the stem or root. For precise assays of carbohydrates including both sugars and starch. more sophisticated methods are required.
