Resumo: | To obtain seeds of high physiological quality, it is of paramount importance to define the ideal harvest moment, which oftentimes corresponds to the period when the physiological maturity is reached. This experiment aimed to study the maturation process and determine the best harvest season of maroon cucumber fruits (Liso Gibão cultivar), in order to reach the maximum physiological seed quality. The flowers were labeled during the anthesis and the fruits harvested at 14, 21, 28, 35, 42, 49 and 56 days after the anthesis (DAA). The fruits had their visual aspects registered by photography analysis and, later, the seeds were extracted for physical (water and dry matter contents) and physiological (germination, seedling emergence, emergence speed index, accelerated aging and electrical conductivity) analyses. It was observed that the seeds reach the maximum dry mass (8.08 mg seed-1) between 47 and 49 DAA. However, the seed physiological maturity, characterized by a maximum germination (70 %) and vigor, occurs at 56 DDA. The best season to harvest seeds with a higher physiological quality takes place from 49 to 56 DDA, when the fruits present a yellowish color. KEYWORDS: Cucumis anguria L., germination, seed maturity. |

KEYWORDS: Cucumis anguria L., germination, seed maturity.Para a obtenção de sementes de alta qualidade fisiológica, é imprescindível a definição do momento ideal de colheita, o qual corresponde, frequentemente, à época em que a maturidade fisiológica é atingida. Objetivou-se avaliar o processo de maturação e determinar a melhor época de colheita de frutos de maxixe (cultivar Liso Gibão), visando à máxima qualidade fisiológica das sementes. As flores foram etiquetadas durante a antese e os frutos colhidos aos 14, 21, 28, 35, 42, 49 e 56 dias após a antese (DAA). Os frutos tiveram os seus aspectos visuais registrados por meio de fotografias e, posteriormente, as sementes foram extraídas para a realização de análises físicas (teor de água e matéria seca) e fisiológicas (germinação, emergência de plântulas, índice de velocidade de emergência, envelhecimento acelerado e condutividade elétrica). Verificou-se que as sementes atingem o máximo de massa seca (8,08 mg semente-1) entre 47 e 49 DAA. No entanto, a maturidade fisiológica das sementes, caracterizada pelo máximo de germinação (70 %) e vigor, ocorre aos 56 DAA. A melhor época para realizar a colheita das sementes com maior qualidade fisiológica ocorre de 49 a 56 DAA, quando os frutos apresentam coloração amarelada.
