The purpose of this research was to verify the efficiency of physical and biochemical indices in determining the physiological maturity of Tabebuia aurea seeds, as well as to evaluate the post-harvest storage of fruits with different maturation stages on germination and vigor. For this, 200 fruits were classified as dark green (stage I), light green (stage II), and light brown (stage III) epicarp. Freshly harvested fruits were evaluated for length, width, and weight and their seeds for length, width, thickness, thousand-seed weight, water content, electrical conductivity, and chemical composition. Subsequently, a factorial consisting of three maturation stages and four storage periods of fruits (0, 5, 10 and 15 days) were used, and water content, germination, germination speed index, root length, shoot length, and seedling dry matter were evaluated. Physical and biochemical indices can be used as maturation indicators in T. aurea seeds, except fruit length, seed thickness, electrical conductivity, and protein content. The maximum germination and vigor of T. aurea seeds were obtained in fruits at stages I (dark green) or II (light green) associated with post-harvest storage of fifteen days.

“…Unlike the species P. angulata and P. peruviana, among other species of the genus, the changes in the color of calyx and fruit for the evaluated varieties are not gradual throughout the developmental stages (Rodrigues et al 2012, Carvalho et al 2014. Changes occurred only in the final maturation stages.…”

The Physalis ixocarpa species has an interesting performance in hot and dry regions. However, there has been a lack of information about the influence of edaphoclimatic conditions, during the growing period, on the physical and physicochemical characteristics of the fruits. This study aimed to evaluate the characteristics of ‘purple' and ‘green' fruits of the P. ixocarpa species, according to the growing season, in the semi-arid region of the Bahia state, Brazil. A randomized block design was used, in a 2 x 2 x 5 factorial scheme (variety x growing season x fruit maturation stages), with three replications. The following characteristics were evaluated: color, fresh weight, length, diameter and total soluble solids contents of the fruits. The changes in the characteristics of the fruits follow the same tendency during maturation, for both evaluated varieties, with the best characteristics being observed when the calyx is green, with dry parts, completely expanded and ruptured. The growing season has a significant effect on the characteristics of the fruits, with May to August presenting the best environmental conditions for growing in the semi-arid region of the Bahia state.

“…This research was conducted in the Seed Analysis Laboratory of the Federal Institute of Education, Science and Technology of Pará (IFPA), Castanhal, PA, Brazil. Mature Physalis angulata L. fruits, with green calyx (CARVALHO et al, 2014), were collected manually from 20 spontaneous plants growing in an area of the IFPA's Castanhal campus (1°17′49″S, 47°55′19″W, 41 m above sea level).…”

“…It is an annual herbaceous plant with high pharmacological and agroindustrial potential (GUIMARÃES et al, 2010;OLIVEIRA et al, 2011) and propagated by seeds (OLIVEIRA et al, 2015). However, because it essentially is a wild species, with continuous flowering and irregular maturation, the occurrence of seeds with different levels of physiological quality (SANTIAGO et al, 2019), as well as low expression of their quality (CARVALHO et al, 2014), is common.…”

Physalis angulata L. (Solanaceae), popularly known as ‘camapu’, has high pharmacological and agroindustrial potential. However, because it essentially is a wild species, studies on the physiological quality of its seeds are still scarce. In this sense, the objective was to evaluate the physiological performance of P. angulata seeds as a function of pre-germination treatments with chemical promoters. For this, germination, first germination count, germination speed index and seedling emergence tests were performed. The substrate was previously moistened with solutions of gibberellic acid - GA3 (0.00, 0.02, 0.04, 0.06 and 0.08%), potassium nitrate - KNO3 (0.0, 0.2, 0.4, 0.6, 0.8 and 1.0%) and Stimulate® (0.00, 0.25, 0.50, 0.75, 1.00, 1.25 and 1.50%). Each chemical promoter constituted an independent experiment, in a completely randomised design, with four replicates of 25 seeds each. The three chemical promoters enhanced the physiological performance of P. angulata seeds, and the concentrations of 0.05% GA3, 0.4% KNO3 and 1.0% Stimulate® were most suitable.
