Caloric analyses of the distribution of energy were carried out for Suregrow 125 and DPL-50 cotton plants 40, 101, and 115 days after emergence and for ripened cotton. For these analyses, plants were harvested, dried, weighed, and subsequently they were analyzed for protein, crude fat, lignin, cellulose, hemicellulose, nitrogen-free solubles, and total gossypol by standard AOAC methods. In ripened cotton, approximately twice as much caloric energy was apportioned to seed in comparison with lint. About half of the caloric content was constituted in lint and seed, the remainder apportioned to vegetative tissues. With 40 day plants, the content of nitrogen-free solubles was high and decreased steadily through the 101st and 115th days with a concominant increase in cellulose, hemicellulose and lignin. Higher lint production might be achieved with a concominant decrease in seed production, perhaps as the result of some genetic strategy.
