“…A reduction in chlorophyll a and b values of the calyx as a result of the advance of fruit development was also observed by Barroso et al (2017), who examined the maturation of P. ixocarpa L. fruits and described minimum chlorophyll a and b values of 0.09 and 0.26 mg g -1 in the calyx, respectively, in fruits harvested at 55 DAA. of P. peruviana L., several authors have stated that these fruits are a significant source of carotenoids and phenolic compounds, which may vary depending on the fruit development stage as well as storage conditions (V. L. A. G. Lima et al, 2005;Ferreyra, Vinã, Mugridge, & Chaves, 2007;Veberic, Colaric, & Stampar, 2008;Severo et al, 2010).…”

Physalis peruviana L. has great nutritional value and economic viability, representing an innovation for Brazilian horticulture. However, knowing the ideal point of harvesting fruits of this species is a key factor in this process that allows maximum post-harvest utilization, providing better quality and minimal losses when the fruit is harvested at physiological maturity. Therefore, this study was conducted to characterize the physiological maturity of Physalis peruviana L. fruits. The experiment was laid out in a completely randomized design in which the treatmentscorresponded to different stages of fruit and seed maturation (20, 27, 34, and 41 days after anthesis [DAA]), with four replicates. The analyzed variables consisted of colorimetry (lightness, chroma and hue angle) of calyx and fruit; fresh weight, diameter (transverse and longitudinal), firmness, pH, total soluble solids, titratable acidity, total soluble solids:titratable acidity ratio, vitamin C and phenolic compounds of fruits; and carotenoids and chlorophyll (a and b) of calyx. The obtained data were subjected to analysis of variance and polynomial regression. Fruits intended for consumption must be harvested after 35 DAA, at which time yellow color and excellent organoleptic and nutritional qualities were observed.

“…Such advancement to be germinable is rather similar to the after-ripening process to overcome morphological dormancy in seed, through which cell development events continue and ultimately allow protrusion of the radicle (Pollock and Roos, 1972). The capability of the seeds to sprout despite detachment from tree prior to full ripeness of fruits has also been described for Physalis peruviana (Solanaceae) (Diniz and Novembre, 2019), Poincianella pluviosa (Leguminosae) (Silva et al, 2015), some epiphytic plants from the family Bromeliaceae (Correa and Zotz, 2014) and Phalaenopsis amabilis hybrids (Orchidaceae) (Schwallier et al, 2011). In the case of S. myrtifolium, the germinability of the seeds in the unpalatable semi-ripe fruits, followed by normal seedling development, could be an adaptation that is vital for the regeneration success of this plant species, as the ripe fruits are highly in demand by animals.…”

To plant Syzygium myrtifolium Walp. on harsh urban sites, planting materials of seed origin having better developed tap roots are preferred compared to those propagated from stem cuttings. However, fully ripe fruits at 8 weeks after fruit set are heavily lost to birds. In the current study, the unpalatable semi-ripe fruits at 7 weeks were found suitable for propagation. The seeds from the semi-ripe fruits showed mean germination rate of 93% and developed normal seedlings within 1 week, although continued growth with increases in size and fresh weight (FW) in the fruits and seeds was significant towards completion of fruit ripening. Thus, harvesting of fruits within the short period between these two fruit developmental phases is critical in the seed procurement process of this plant species. At the semi-ripe stage, pericarp exhibiting mixture of red and black colour can be a practical guide to indicate the suitable time for harvesting the fruits. Nonetheless, subsequent desiccation trial aimed to determine the storability of the seeds at postharvest found that the seeds obtained from both the semi-ripe and fully ripe fruits had drastic loss of germinability at seed moisture content of approximately 0.3 g H2O/g FW. Storage of the seeds above this relatively high moisture level for future planting was detrimental because the seeds age rapidly when they remain metabolically active with high respiration rates. Microbial infestation will also be an added problem during seed storage. Therefore, the seeds need to be sown fresh.

“…pendulum seeds reached maximum mass at 74 DAA, and the physiological maturity of seeds (maximum germination and vigor) occurred between 70 and 81 DAA (Figueiredo et al, 2017). Physalis peruviana seeds showed higher germination and vigor when obtained from fruits harvested from 75 DAA and 60 DAA, respectively, after mass maturity (Diniz and Novembre, 2019).…”

“…Thus, the harvest must coincide with, or the closest to, the physiological maturity point of seeds when deterioration is minimal (Dias and Nascimento, 2009). In this sense, studies on the seed maturation process are essential, as the resulting knowledge allows the determination of the moment when the seeds reach the ideal quality and the appropriate time for harvest (Diniz and Novembre, 2019).…”

Maturation and germination of Trichosanthes cucumerina L. seeds

Trichosanthes cucumerina L. (Cucurbitaceae) is a traditional fruit vegetable grown by family farmers in the Amazon. This study aimed to evaluate seed maturation as a function of age and fruit morphological characteristics, and the effect of different temperatures on seed germination of accessions of the species. A completely randomized design was adopted in the maturation study, with five treatments (fruit age: 20, 30, 40, 50, and 60 days after anthesis - DAA) and four replications. Seed quality was evaluated through dry mass, water content, germination, and vigor variables, while the fruits were evaluated for physical characteristics and the number of seeds. A completely randomized design in a 3 (temperatures: 20, 25, and 30 °C) x 7 (accessions: PIN I, PIN II, TSA, MAO, UTB, ITA, and IMI) factorial scheme, with four replications was adopted in the study of germination temperatures. Seed quality was evaluated using germination and vigor tests. Seeds reach physiological maturity around 50 DAA. The fruits are partially or completely orange or reddish-orange in color at that time. The temperature of 30 °C favored the seed germination process, resulting in a higher percentage and germination rate.
