Abstract
By using tagged gynophores and appearance of the nuts, samples of seeds were obtained at stages from 18 days after the entrance of the gynophores into the soil to 70 days when the seeds were over-mature. During the 2 weeks preceding maturity, fat and protein increase only slightly on % basis but considerably on a wt. per seed basis. The ratios of protein/carbohydrate, fat/carbohydrate, and fat/protein increased as the seeds developed. Although the % of reducing sugars, sucrose, and starch decreased during the early stages of growth, sucrose, the principal soluble sugar, increased near maturity so that the total % of sugars and starch approached a constant value in the fortnight preceding maturity. During development of the shell, the % of dry matter, fat, protein, sugars, and starch decreased while hemicellulose increased. Virginia Bunch peanuts require about 130 days from planting or 60 days from entrance of the gynophores into the soil to attain maturity.
