“…The maximum seed dry weight values for the 'green' (96.6 mg) and 'purple' (96.0 mg) varieties were obtained when collected from fruits in the S4 and S5 stages, respectively, coinciding with the stages in which greater reductions in water content occurred. These results are consistent with those obtained by Barroso et al (2017), with P. ixocarpa seeds, and by Santiago et al (2019), with Physalis angulate seeds.…”

Physalis ixocarpa is an edible fruit with great economic importance in many countries. The use of high-quality seeds is essential for the success of the crop, so their harvest should be carried out at their maximum point of physiological maturity. This study aimed to verify the influence of the growing season and fruit maturation stage on the seed physiological maturity of two P. ixocarpa varieties (‘green’ and ‘purple’) grown in the Brazilian semi-arid region. The water content, dry weight, germination percentage and seedling emergence were evaluated. The growing season influenced the seed maturation process of the two evaluated varieties, with a more pronounced effect for the ‘purple’ one. To obtain higher-quality seeds, the cultivation in the Brazilian semi-arid region can be carried out from May to August and the collection of fruits to obtain seeds from the stage 4 of maturation.

“…However, for some species, the maximum physiological quality occurs before (Capsicum baccatum var. pendulum; Figueiredo et al 2017) or after (P. angulata; Santiago et al 2019) the seeds reach the maximum dry weight.…”

“…These figures show that both fruit weight and diameter were reduced with the maturation process as a function of water loss resulting from shrivelling of fruits during the latter stage of maturity when the rains had ceased. Similar results were reported by Silva (2002) with the fruit size of Cnidosculus phyllacantus reaching maximum values 53 days after flowering (DAF) while Physalis angulata L. from the Solanaceae family also reached maximum fruit weight and diameter at 35 DAA (Santiago et al, 2019). In S. melongena L., Kortse et al (2017) recorded maximum fruit diameter and weight at 35 days after anthesis.…”

This work aimed at determining the optimum harvest time of African eggplant (Solanum aethiopicum L.) seeds, cv. Oforiwa and cv. Kpando for maximum physiological seed quality under tropical (TCC) and temperate oceanic climatic (TOC) conditions. Fruit morphological metrics such as fruit weight and size were also related to seed physiological quality. Seeds were harvested at different maturation stages from 20 to 82 days after anthesis (DAA). Seed quality was assessed according to moisture content, dry seed weight, seed length, thousand seed weight, percentage germination and emergence. The results indicated that seeds harvested precociously (20 and 34 days after anthesis), did not germinate or recorded very low percentage germination (0-20%). Considering all the fruit morphological traits and seed quality variables measured, the results indicate that maximum seed quality (that is, germination, emergence, seed weight and mean germination time) are obtained from fruits harvested at 76 DAA. The physiological maturity (PM) (maximum seed dry weight) for cv. Oforiwa was attained at 62 DAA while cv. Kpando took 14 days more to reach physiological maturity but coincided with maximum germination at 76 DAA. The results further showed that fruit characteristics such as weight and size are associated with seed physiological quality in African eggplant. It is thus recommended that fruits of African eggplant cv. Oforiwa and cv. Kpando should be harvested at 70 to 76 DAA for maximum seed germination and emergence.

“…Considering the yield, P. angulata plants presented similar number of fruits between the two cultivation periods (Table 2). Regarding the average fruit weight, the results were superior to those obtained by Thomé et al (2010) in Paraná (1.44 g / fruit) and Santiago et al (2019) in Pará (1.8 g / fruit), and lower than that observed by Oliveira et al (2011) in the Amazon (4,33 g / fruit). Different situation was observed for P. ixocarpa plants that were influenced by the period in which sowing occurred.…”

The Physalisgenus is composed of species with economic andmedicinal importance, its cultivation is expanding in Brazil,andis neededresearch on the performance of species in different regions of the country. Thus, the objective was to characterize the growth, development and yield of Physalis angulataand Physalis ixocarpaspecies cultivated in three sowing seasons in Bahia's semiarid region.The days after sowingwere determined for the occurrence of vegetative and reproductive stages, and the length and diameter of the main branch were evaluated weekly. At the end of cultivation, the number and total weight of fruits per plant were determined. The plants sown in April showed the best results, as floweringprecocity, higher productivity and growth close to other producing regions, which is the best period for the cultivation of species. P. angulatais a more tolerant species and can be sown at different periods without compromising yield. High temperatures combined with scarcity of rainfall compromise the development of plants of both speciesof Physalis.
