Morphological stages of development for little bluestem (Andropogon scoparius) appeared to follow a sequential pattern. Each stage molded into the succeeding stage with no sharp change over time. The development of little bluestem tillers destined to flower was divided into five stages: (1) tiller formation, (2) spring vegetative, (3) culm elongation, (4) flowering and maturation, and (5) fall vegetative. Leaf—sucrose concentration and root—starch concentration were the best physiological indicators of changes in morphological stages of development. Trends of ethanol—extractable carbohydrate concentrations from foliage material correspond closely to available photosynthetic area. The major storage carbohydrate in little bluestem was starch. Storage carbohydrates were utilized during formation of fall and spring tillers and during culm elongation.
