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 analyzed for protein, crude fat, lignin, cellulose, hemicellulose, nitrogen-free solubles, and total gossypol according to standard AOAC methods. In ripened cotton, approximately twice as much caloric energy was found to be released in the combustion of 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-old plants, the content of nitrogen-free solubles was high and decreased steadily through the 101st and 115th days after emergence with a concomitant increase in cellulose, hemicellulose, and lignin.
