Abstract The objective of this work was to evaluate physical and chemical fruit parameters of new strawberry genotypes underfield conditions. The study was carried out during the 2018 and 2019 seasons. Twelve genotypes from the breeding program of Embrapa and two commercial cultivars (Camino Real and Merced) were evaluated. The assessed parameters were: average fruit number, average fruit weight, soluble solids, titrable acidity, and the soluble solids/titrable acidity ratio. Among the studied strawberry genotypes, the 8-1, 35-22 ('BRS DC22'), 31-13, 7-5, and 32-2 selections produce more fruits per plant. Among the new genotypes, 'BRS DC25' (Fênix) and 31-13 present the best average fruit weight in both evaluated seasons. The highest sugar content is observed in genotypes 35-22 ('BRS DC22') and 65-2, whereas 8-1 and 'BRS DC25' (Fênix) show the highest acidity. The 7-5, 35-22 ('BRS DC22'), 34-2, and 35-6 genotypes present the best soluble solid/acidity ratio. conditions 201 seasons Camino Merced number solids solidstitrable ratio 81, 81 8 1, 1 3522 35 22 35-2 BRS DC22, DC22 DC , 3113, 3113 31 13, 13 75, 75 7 5, 5 7-5 322 32 2 32- plant DC25 Fênix (Fênix 31-1 DC22' 652, 652 65 2, 65-2 8- 342, 342 34 34-2 356 6 35- solidacidity solid 20 352 3 DC2 311 7- 31- 65- 34-

Resumo O objetivo deste trabalho foi avaliar parâmetros físicos e químicos de frutos de novos genótipos de morangueiro em condições de campo. O estudo foi realizado durante as safras de 2018 e 2019. Foram avaliados 12 genótipos do programa de melhoramento genético da Embrapa e duas cultivares comerciais (Camino Real e Merced). Os parâmetros avaliados foram: número médio de frutos, massa média de frutos, sólidos solúveis, acidez titulável e relação sólidos solúveis/acidez titulável. Entre os genótipos de morango estudados, as seleções 8-1, 35-22 ('BRS DC22'), 31-13, 7-5 e 32-2 produzem mais frutos por planta. Entre os novos genótipos, 'BRS DC25' (Fénix) e 31-13 apresentam a melhor massa média de frutos nos dois períodos avaliados. O maior teor de açúcar é observado nos genótipos 35-22 ('BRS DC22') e 65-2, enquanto 8-1 e 'BRS DC25' (Fênix) apresentam a maior acidez titulável. Os genótipos 7-5, 35-22 ('BRS DC22'), 34-2 e 35-6 apresentaram a melhor relação sólidos solúveis/acidez. campo 201 2019 1 Camino Merced. Merced .

ABSTRACT Blackberries have a short post-harvest conservation period, making it necessary to optimize harvest and storage conditions. The objective of this study was to evaluate the impact of refrigerated storage and maturation stage on the physicochemical quality of ‘BRS Cainguá’ blackberries, produced in an organic system. Blackberries from an experimental orchard, were harvested at three ripeness stages (RS), with RS1 being fruits with 100% red skin; RS2 skin 50% red and 50% black; and EM3 100% black skin. The samples were stored in a cold chamber at 4±0.5ºC and 90-95% RH for 12 days. The evaluations were carried out after 0, 3, 6, 9 and 12 days of storage, for: weight loss (WL), soluble solids (SS), pH, titratable acidity (TA), ratio (SS/TA) and color parameters. Blackberries harvested in RS3 had the highest SS content, lowest TA and the highest SS/TA ratio and pH. During storage, TA and WL showed decreasing and increasing linear responses, respectively, regardless of the RS of the fruits. Harvesting based on the skin color of ‘BRS Cainguá’ blackberries influences the physicochemical quality and postharvest conservation. Fruits harvested with 100% black skin, have the best quality and are the most suitable for subsequent refrigerated storage. post period conditions BRS Cainguá system orchard RS, , (RS) 100 50 EM 405ºC ºC 4 0 5ºC 9095% 9095 90 95% 95 90-95 1 3 6 WL, (WL) SS, (SS) pH TA, (TA) SSTA (SS/TA parameters content responses respectively (RS 10 5 909 90-9 (WL (SS (TA 90-

ABSTRACT The production of strawberry seedlings in a soilless cultivation system can be an alternative for the production of seedlings of high physiological and sanitary quality. The objective of this study was to evaluate the influence of the use of different nutrient solutions in mother plants on the production and quality of strawberry seedlings of the Aromas and Camarosa cultivars. The experiment was carried out in two crop cycles: the first cycle in 2016/2017, where four different nutrient solutions (1; 2; 3 and 4) were used for the nutrition of the parent plants of the cultivars under study and the second in 2017/2018, when the most productive solutions (nutrient solution 3 and 4) based on the results of the first cycle were used, together with the two cultivars. The propagules produced were collected, evaluated and rooted in substrate-filled trays, forming plant plugs, which were evaluated for quality. Nutritional solutions influence the propagative potential of the parent plants more than the physiological quality of the plug plant seedlings produced, when they are formed on substrates that provide nutrients. The nutrient solution 4 is the most recommended for the production of strawberry seedlings of the cultivars Aromas and Camarosa, in a soilless system.
