“…The ascorbic acid content of ripe fruits was 38.25 mg 100g -1 , lower than those verified by Reis et al (2015), where 'Tainung 1', L33 and H36.45 papayas, from the 'Formosa' group, presented Vitamin C concentrations of 70.09 mg100g -1 , 85.45 mg100g -1 and 93.64 mg100g -1 , respectively. However, as mentioned by Manica (2006), ascorbic acid concentrations in pulp range from 35 mg 100g -1 to 84 mg 100g -1 .…”

“…For ripe fruits, only firmness varied according to treatments (P ≤ 0.05). The mean values of the analyzed variables are presented in Table 1 and are among those obtained by Fernandes et al, (2010) and Viana et al (2015).…”

“…The other components that characterize color, i.e., lightness and chroma, increased in ripe fruits, indicating higher lightness and peel color intensity, respectively, when peel becomes yellow. Fruit pulp is orange-red, according to the observed mean ° hue value of 58.83°, being an important sensory characteristic, as verified by Viana et al (2015), and consumers prefer fruits of red pulp varieties.…”

“…The tendency of lower fruit acidity at harvest point provided higher soluble solids / titratable acidity ratio, since, on average, the soluble solids content was very similar among fruits at different degrees of ripeness. According to Viana et al (2015), the SS / TA ratio represents the balance between sugars and acids and directly contributes to flavor and aroma formation. Generally, fruits with higher SS / TA values have more pronounced sweetness and lower acidity, being preferred by consumers.…”

Resumo A significant portion of papaya production in the state of Minas Gerais originates from irrigated crops, and irrigation management using the partial root zone drying technique (PRD) is a fundamental alternative to reduce water waste. This study aimed to evaluate the quality of ‘Tainung 1’ papaya produced under PRD in semi-arid conditions of northern state of Minas Gerais. PRD treatments were composed of reduction of the calculated irrigation water (CIW) by 50%, applied on one side of the irrigation line, with alternation of 7, 14 and 21 days or without alternation and full irrigation, applying 100 % CIW in both lateral plant rows. Each experimental plot consisted of ten plants, and from six plants, fruits were harvested for evaluations at harvest point and when ripe. At harvest point, fruits had peel color, titratable acidity, ratio, pulp size and thickness similar to those produced without water deficit. Firmness, soluble solids content, fresh mass and central cavity diameter are distinct as a function of PRD condition. When ripe, only firmness varied according to PRD treatments. The quality of ‘Tainung 1’ papaya produced by partial root zone drying in semi-arid conditions was not compromised.

“…Parsley is an herb in the Apiaceae family, and its leaves are widely used in cooking, either cooked or raw. It is also considered an important source of vitamins; in addition, it has compounds such as flavonoids, carotenoids and ascorbic acid (Maodaa et al, 2016), which are bioactive compounds with antioxidant capacity that have been associated with the protection of human health against chronic degenerative diseases (Lako et al, 2007;Reis et al, 2015).…”

Brackish waters may vary in their chemical compositions, interfering with different plant responses to stress; therefore, the present study aimed to evaluate the production components of parsley plants subjected to levels of electrical conductivity in nutrient solutions with an initial ECns of 1.58 dS m-1, which was solubilized in water with the following water electrical conductivity configurations (ECw): 0.12 (control), 1.12, 2.12, 3.12, 4.12 and 5.12 dS m-1, resulting in six isosmotic levels (ECns = 1.7, 2.7, 3.7, 4.7, 5.7 and 6.7 dS m-1) in an interaction with four types of salt: NaCl, CaCl2, MgCl2 and KCl. The experimental design was completely randomized in a factorial scheme with five replicates. Two strategies were used to restore the volume consumed by the parsley plants, and the replacement was made with municipal-supply water (ECa = 0.12 dS m-1) in the first strategy and with the respective brackish waters in the second strategy. The total fresh and dry weights of the shoots and roots were evaluated as well as the total dry mass percentage of the shoots and roots. The responses of the plants to the different cationic natures was more evident at the highest levels of electrical conductivity tested, and the use of municipal-supply water to replace the evapotranspired depth mitigated the deleterious effects of salinity. In addition, greater reductions were observed in the fresh and dry mass when the replacement of the volume consumed was with the brackish waters.

The germination of papaya seeds is slow and uneven, usually due to inhibitors present in the sarcotesta; however, some removal procedures may cause physical damage, negatively interfering in the physiological quality and field performance. This study aimed to evaluate the physical and physiological quality of papaya seeds submitted to methods of sarcotesta removal by image analysis. Papaya Formosa ‘Tainung 01' seeds were submitted to the following methods of sarcotesta removal: fermentation + sieve, sand + sieve, sieve and blender + sieve. After the sarcotesta removal, the seeds were submitted to tests of germination, first germination count, germination speed and seedling length. For the image analysis, the seeds without sarcotesta were submitted to the X-ray test and to a computerized analysis of seedling images by the SVIS® software. The methods used were only promising for the sarcotesta removal, while the blender + sieve method obtained the highest physical and physiological seed quality, in addition to performing the best sarcotesta removal. However, the image analysis using the SVIS® software allowed to identify the high physical and physiological seed quality using the blender + sieve method, which promoted the highest efficiency in removing the sarcotesta.
