| Abstract | An important aspect of the production of seeds is the determination of the physiological maturity and the ideal moment of harvest to obtain high quality seeds. This work aimed to study the maturation of pepper (Capsicum annuum L.) seeds, “Amarela Comprida” cultivar, in order to determine the physiological maturity of seeds and the adequate moment for seeds harvest. The seeds were obtained from fruits harvested at 20, 25, 30, 35, 40, 45, 50, 55, 60, 65, 70 and 75 days after anthesis (DAA). Before the seeds extraction the fruits were appraised in relation to the weigh, diameter, length and number of seeds per fruit. The seeds were submitted to following tests and determinations: moisture content, dry matter, weight of thousand seeds, germination, first count of germination, speed emergence index, seedling length, controlled deterioration, accelerated aging and electrical conductivity. The experiment was conduted in completely randomized design, with four replications, and the data were submitted to variance analysis and regression. The physiological maturity of pepper seeds, cv. “Amarela Comprida”, happened at 70 DAA, when the seeds presented 46.1% moisture content. The maximum physiological quality of the seeds ocurred between 65 and 70 DAA, indicating that harvest can be made in this moment. |
