Abstract
The objective of this article was to establish, for peanut crop production in Córdoba (Argentina), the incidence of fruit maturity on seed physiological quality, with the purpose of determining the best maturity percentage for peanut harvest when the finality is seed production. Fruits obtained under different water conditions were classified by maturity. Maturity profiles and seed dry weight in each maturity class were determined. The seeds of each maturity class were utilized in standard germination, seedling dry weight, and accelerated ageing tests. Irrigation treatment significantly increased the fruit maturity proportion. There was no incidence of maturity on seed standard germination but a slight effect on germination following accelerated ageing. The seedling dry weight, without its cotyledons, was significantly affected by seed maturity.
