The Physalis peruviana L. presents great nutritional value and economic viability, becoming an alternative for the small and medium producer and an innovation for the Brazilian horticulture. However, some information on cultivation, are still scarce. In this context, our objective is to characterizing the phenological phases and productivity of the Physalis peruviana cultivated in a greenhouse in the semiárido paraibano. This work was done in the experimental farm of the Federal University of Campina Grande, campus Pombal, Paraíba. The experiment was driven in a randomized blocks design, with five repetitions, each repetition constituted of five plants. The phenological phases were determined through the height, diameter of the stem, number of leaves, floral buttons, flowers and fruits per plant, production and productivity. The data were submitted to the variance analysis and polynomial regression. The vegetative phase of the Physalis peruviana L. is concluded in a period understood among 32 to 45 days after the transplant (DAT) and the reproductive phase extends until 161 DAT. In the conditions of the semiarid, the crop of the fruits of the Physalis peruviana L. begins to 71 DAT, with a dear productivity of approximately 2 340.95 kg ha-1.

Objective: To analyze the concept of “frailty syndrome” in the literature, according to the method proposed by Walker and Avant. Methods: It is a concept analysis, guided by the method proposed by Walker and Avant, made operational through an integrative literature review. The search in a scientific database was carried out using the descriptors: Frail elderly, syndrome, phenotype, geriatric assessment, and aging. The literary corpus comprised 66 studies. Results: The study found the antecedents and attributes (categorized as physical, sociodemographic, and behavioral/environmental) that integrate the signs and symptoms evidenced in the “frailty syndrome,” as well as the consequences of this concept. The variables were analyzed with emphasis on the conceptions that influence the frailty process of the elderly. Conclusion: The study demonstrated the complexity arising from the multifactorial genesis of the referred syndrome, emphasizing the specificities of the elderly’s frailty. However, we recommend conducting further research involving the phenomenon in question to understand the construct better.

The effect of coatings with different concentrations of tamarind seed starch associated with pomegranate seed oil in ‘Paluma’ guava was investigated in the present work. The fruits were harvested from an orchard in the morning, packed in containers previously lined with paper, and transported to a laboratory, where they were selected, washed, sanitized, and separated at random for the application of each treatment. The experiment design used was completely randomized, in the 6 × 6 factorial scheme, six coatings and six evaluation periods, with 3 replicates made up of 2 fruits. The treatments were: T1 (control or reference sample), without coating; T2 (0.24 mL of pomegranate seed oil/mL of coating); T3 (2% tamarind starch); T4 (1% tamarind starch); T5 (2% of tamarind starch); T6 (3% tamarind starch), T4, T5 and T6 were associated with 0.24 mL/mL of the pomegranate seed oil. The treatments were applied under immersion of the fruits in the solutions and then stored in a refrigerated chamber at 10±2 °C and 80±5% RH, and the evaluations were performed at intervals of 3 days to 12 days of storage. Due to the maintenance of the quality of the fruits, and without sufficient material, it was decided to extend storage time until the 21 days. Thus, the analyses were performed at 0, 3, 6, 9, 12 and 21 days with evaluations at 0, 3, 6, 9, 12, and 21 days. The T6 treatment (3% tamarind starch + 0.24 mL/mL pomegranate seed oil) was more efficient regarding luminosity (L*) of the fruits and delaying color development , expressed by the values of C*, also showing the higher retention in the loss of firmness, lower mass loss and lower soluble solids content, suggesting that this treatment possibly inhibited the degradation of polysaccharides, delaying the ripening process of the fruits.

It is very challenging to the quality of the papaya culture’s fruits (Carica papaya L.) after the crop, especially due to their significance to the international market, that is, their elevated exportation demands. The purpose of this work was the application of biodegradable coatings composed of Scenedesmus sp. and Chlorella sp. associated or not with pomegranate seed oil in ‘Golden’ papaya and to evaluate their effect in the conservation powder-crop. The installation of the experiment was carried out in a completely randomized design, with a 6 x 6 factorial outline, that is, six concentrations (C: control; SO: 0.5% of Scenedesmus sp. + 0.3% of pomegranate seed oil; S: 0.5% of Scenedesmus sp.; CO: 0.5% of Chlorella sp. + 0.3% of pomegranate seed oil; CH: 0.5% of Chlorella sp.; O: 0.3% of pomegranate seed oil) and six evaluation periods (0, 3, 6, 9, 12, and 15 days), stored at a temperature of 18±2 °C with 60±5% RH with three repetitions of two fruits per portion. The use of coverings composed of Scenedesmus sp. and Chlorella sp. in association or not with pomegranate seed oil was proven efficient in the reduction of the breathing tax of ‘Golden’ papaya, delaying the ripening process, and therefore representing a promising alternative for these fruits’ powder-crop conservation. The coating composed of 0.5% of Chlorella sp. + 0.3% of pomegranate seed oil (CO) provided a better powder-crop conservation of ‘Golden’ papaya during 15 days of storage.
