| ABSTRACT The physical, physiological and biochemical changes during the development until the dispersal of rubber tree seeds were evaluated with the purpose of estimating the point at physiological maturity. A total of 30 plants were selected at different points in a commercial planting area and had their flowers marked during the anthesis and every 15 days after marking. Fruits and seeds were collected for analysis of moisture content, dry matter, diameter and length. Details of the anatomy ultra-structure of the seeds were evaluated. The seed emergence, emergency speed index, heat resistant proteins and oxidative stress enzymes were examined. It was observed that fruits reached maximum size at 120 days after anthesis and seeds at 150 days. The seeds... |

| Abstract: The objective of this work was to determine the relationship of the morphological and physiological characteristics of guanandi (Calophyllum brasiliense) fruit and seeds with ripening and harvesting time. The reproductive cycle of a native plant population, located in the coast of the state of Paraná, Brazil, was monitored from anthesis until fruit dispersion, during three years. Monthly harvests were performed, and the morphological and physical aspects (color, size, dry mass, and moisture content) of fruit and embryos were evaluated, as well as the physiological ones (germination and vigor) of seeds. The ripening process of guanandi seeds occurred between 200 and 240 days after anthesis (DAA), with anthesis peak in February and fruit dispersion... |

| ABSTRACT It is important to understand the seed maturation process to determine the time point at which the seeds achieve optimum quality and the ideal time for harvest. This study aimed to study the maturation of Physalis peruviana L. seeds, based on flowering time and age of the fruit. This study was conducted from March to October of 2016 and 2017, in the city of Piracicaba, São Paulo. The plants were cultivated in four blocks using four stems, with spacing of 1.0 m between the plants and of 2.5 m between the rows. As experimental treatments, two flowering time points were defined: 55 and 105 days after transplanting (DAT); in each period, the flowers were marked at the anthesis and the respective fruits and seeds were evaluated at 45, 60, 75, and 90... |

| ABSTRACT Although used as green manure, one of the challenges the cultivation of Crotalaria juncea is the low availability of quality seeds in the market. The harvest at the right time contributes to the achievement of better quality seeds. The objectives of this study were to evaluate the storability and characterize the physical and physiological changes of the seeds harvested at different times. The statistical design was completely randomized with three replications. Treatments consisted of four harvest seasons and two storage periods (0 to 8 months). The samples were collected when the plants reached 40, 60, 80 and 100% of dried pods. The following characteristics were evaluated: time for drying, moisture content, dry matter accumulation, physical... |

| Study of sunn hemp seed development and maturation was studied at the Department of Plant Science, Faculty of Natural Resources, Prince of Songkla University, Hat Yai campus, Hat Yai, Songkhla, during March-June, 2008. The blooming flowers were tagged to indicate the date of flowering. Pods at 10, 13, 16, 19, 22, 25, 28, 31, 34, 37, 40, 43 and 46 days after flowering were harvested to investigate pod color, seed color and seed quality. The results showed that the sunn hemp had 6 developmental stages of pod color which were green, yellow-green, light grey-green, dark greygreen, grey-brown and grey-brown-black at 10-16, 19-28, 31, 34, 37-40 and 43-46 days after flowering, respectively. The sunn hemp seeds were capable of germination at approximately 25 days... |
