“…The asynchronous maturation of hardy species (Schubert and Walters, 2022), such as A. glazioveana, makes it impossible to harvest a greater number of seeds within the same period at the same degree of maturation. Thus, the possibility of post-harvest maturation makes it possible to gather a greater number of seeds, which will be viable after a period of storage (Santos et al, 2019).…”

Ateleia glazioveana Baill. is a pioneer, rustic and can be used for forest recovery. This work aimed to study the process of physiological maturation of this species. The research was carried out in the city of Alegre - ES, the trees were identified in the floral anthesis and accompanied during the filling of the fruits and development of the seeds until the complete maturation. The fruits were harvested at the following stages 7, 14, 21, 28, 35 and 42 days after anthesis, and characterized according to: morphometry, moisture, fresh and dry mass of fruits and seeds, germination, germination speed index, shoot and root length and dry mass of seedlings. The regression equations were adjusted for the main characteristics analyzed as a function of the harvest period. The point of physiological maturity of timbó occurred at 42 days after anthesis.

“…This species is mainly explored in the timber industry and the recovery of degraded areas [2]. This species is also explored in the chemical and pharmacological industry due to the presence of compounds with antinociceptive and antiedematogenic properties that help treat cancer and control mosquito larvae Aedes aegypti [3].…”

Studies about the viability and vigor of seeds during storage, especially on the characterization of enzymatic changes, may increase the harvesting efficiency of immature seeds and guarantee their viability for a prolonged period. Therefore, this study aimed to evaluate the behavior of immature seeds of Tabebuia caraiba during storage. For this, thirty selected mother plants at the anthesis stage located in São João do Cariri and Sumé, Paraíba, Brazil were selected. Flowers of each tree were marked, and the fruits were harvested at 35, 42, and 49 days after anthesis (DAA) and characterized according to their maturation stages. The seeds from each maturation stage and city were packed in paper bags and stored in a refrigerator (6 ± 2 °C) for 360 days. The seed quality, seedling vigor, and enzymatic activity of superoxide dismutase (SOD), catalase (CAT), and peroxidase (POX) were evaluated at the beginning of the storage period and intervals of 90 days. The seeds of T. caraiba harvested at 35, 42, and 49 DAA maintained high viability for 360 days of storage. T. caraiba seeds stored for 360 days withstood with high vigor when harvested at 42 DAA. The CAT, SOD, and POX activity was correlated to the deterioration process of the seeds under storage conditions. HIGHLIGHTS• The harvested T. caraiba seeds maintain high viability for 360 days of storage.• Seeds harvested at 42 DAA have higher quality.• The SOD and CAT activity is not related to the deterioration process of the seeds under storage.• POX increases activity in response to the seed storage period.

“…During seed development/maturation, physiological quality increases, with changes in moisture content, accumulation of dry mass, germination potential, and vigor, making it a vital period for development of viable seeds (Carvalho and Nakagawa, 2012;Bing et al, 2023). Consequently, various studies have assessed the changes during seed maturation, aiming to evaluate morphological and physiological modifications and their effects on post-harvest (Muller et al, 2016;Hell et al, 2019;Santos et al, 2019;Guarriz et al, 2022;Mescia et al, 2022).…”

Studies on seed maturation directly contribute to obtaining seeds with a higher standard of physical, physiological, and sanitary quality. Thus, the aim of this study was to verify the morphological and physiological changes during the maturation of Cenostigma tocantinum Ducke seeds. The maturation stages were analyzed: I (293 days after anthesis - DAA), II (322 DAA), III (350 DAA), and IV (356 DAA) through visual, biometric analyses, and quantification of moisture content, dry mass, viability, and seed vigor. During the development of C. tocantinum seeds, changes in fruit coloration and an increase in fruit and seed length, width, and thickness were observed. In the initial stages, the seeds had a high moisture content, which decreased in the later stages. On the other hand, the dry mass of the seeds showed an inversely proportional behavior to the moisture content. Physiological variables performed better in stages III and IV, except for electrical conductivity. It can be concluded that C. tocantinum seeds showed superior physiological quality in stages III or IV, recommending the collection of seeds during these maturation periods.
