Desempenho agronômico de novos cultivares de morango no sul do Brasil

The choice of cultivars to be used by strawberry farmers is essential since it could determine the success of the crop. The present study aimed to evaluate the productive and qualitative performance of strawberry genotypes grown in Vacaria, RS, Brazil. Twelve strawberry genotypes were compared, constituting the different treatments: cultivars Strawberry Festival, Oso Grande, Jonica, and Pircinque, and selections FRF PA3, FRF CE 51, FRF CE 56, FRF PIR 29, FRF PIR 54, FRF 85.04, FRF 149.18, and FRF 102.21. The seedlings were transplanted on May 13, 2014, in a semi-hydroponic cultivation system, adopting a randomized block design with four blocks and an experimental unit of ten useful plants. The variables evaluated were the number of fruits, total production per plant, productivity, commercial productivity, fresh fruit mass, commercial percentage, soluble solids, titratable acidity, soluble solids to total acidity ratio, pulp firmness, and production seasonality. The mean values ​​were subjected to an analysis of variance and multivariate analysis, and their means were compared by the Scott-Knott test at a 5% error probability. Cultivar Strawberry Festival and selection FRF 102.21 showed higher productions (1138 g plant-1 nd 1019 g plant-1, respectively) and quantities of fruits produced (85 un plant-1 and 87 un plant-1, respectively). Cultivar Jonica and selection FRF 85.4 showed higher percentages of marketable fruits. The Pircinque cultivar was prominent for sugar content, presenting a value 24% superior to the general average of the cultivars. Cultivars Strawberry Festival, Jonica, and Pircinque and selection FRF 102.21 showed the highest qualitative and quantitative gains for the region of Vacaria, RS, Brazil.A escolha dos cultivares a serem utilizadas pelos produtores de morangos é fundamental, pois pode determinar o sucesso da cultura.

A cultivar Jonica e a seleção FRF 85,4 apresentaram maior porcentagem de frutos comerciáveis. O cultivar Pircinque se destacou-se pelo seu teor de açúcares, apresentando um valor 24% superior à média geral dos cultivares. As cultivares Strawberry Festival, Jonica e Pircinque e seleção FRF 102,21 apresentaram os maiores ganhos qualitativos e quantitativos para a região de Vacaria, RS.

Características produtivas e qualitativas de genótipos de morangueiro no Planalto Catarinense

To produce strawberries on a commercial scale, it is necessary to choose the cultivars best adapted to the growing site. This work aimed to compare strawberry genotypes regarding production and fruit quality, in the municipality of Lages, State of Santa Catarina, Brazil, during the 2017/2018 harvest season. In this work, 15 genotypes were evaluated, five commercial cultivars and ten advanced selections. The experimental design was in randomized blocks, with four replicates and plots of 11 plants. The cultivation system used was in the soil of an open field, in beds of approximately 90 centimeters, with three rows per bed. Planting distance was of 30 centimeters between rows and plants. The Sabrina cultivar showed the highest production (1,231.77 g plant-1) and number of fruits (78.48 fruits plant-1). The highest quality fruits were obtained from the selections FRF PIR 256.4, FRF 104.1, FRF 57.6, FRF LAM 119.1 and cultivar Pircinque, characterized by soluble solids/titratable acidity ratios above 15. In the productive cycle in question, cultivar Sabrina presented the best performance, demonstrating the potential for recommendation to the producers of the South Plateau of State of Santa Catarina.Para produzir morangos em escala comercial, é necessário escolher as cultivares melhor adaptadas ao local de cultivo. Objetivou-se com este trabalho confrontar genótipos de morangueiro quanto a aspectos de produção e qualidade de frutos, no município de Lages, em Santa Catarina, no ciclo agrícola 2017/2018. Foram avaliados 15 genótipos, sendo cinco cultivares comerciais e dez seleções avançadas. O delineamento experimental utilizado foi em blocos casualizados, com quatro repetições, e parcelas constituídas por 11 plantas. O sistema de cultivo utilizado foi no solo, em campo aberto, em canteiros com aproximadamente 90 centímetros de largura, com três linhas de plantio por canteiro. A distância de plantio foi de 30 centímetros, entre fileiras e plantas. A cultivar Sabrina obteve a maior produção (1.231,77 g planta-1) e número de frutos (78,48 frutos planta-1). Com as seleções FRF PIR 256.4, FRF 104.1, FRF 57.6, FRF LAM 119.1 e a cultivar Pircinque se obtiveram os frutos de qualidade superior, caracterizados por médias acima de 15 para a relação sólidos solúveis / acidez titulável. No ciclo produtivo em questão, a cultivar Sabrina apresentou o melhor desempenho, demonstrando potencial para ser recomendada aos produtores da região do Planalto Sul Catarinense

Planting Density Interferes with Strawberry Production Efficiency in Southern Brazil

In the search for more efficient production systems, many changes have occurred in the strawberry production sector. Planting density is one of the management techniques that most interferes with the quality of fruits and production aspects. This study aimed to evaluate the effect of different planting densities on the photosynthetic characteristics, fruit quality, and production of the strawberry cultivar Pircinque. The study was conducted in the 2018/2019 and 2019/2020 harvests in Lages, Santa Catarina, Brazil. The treatments consisted of plant spacing of 5, 10, 15, 20, 25, and 30 cm. The experimental design was in randomized blocks, with four blocks and plots of 20 plants. Plant spacing interfered with fruit quality, photosynthetic efficiency, production, productivity, and economic return. Due to the fruits of Pircinque having a higher quality than other cultivars, the planting spacing between 5 and 15 cm allows meeting the fruit’s main production and quality requirements. However, it is up to the producer to adapt the management if opting for higher planting densities, which allow for a greater economic viability of the business

Initial Crown Diameter Influences on the Fruit Yield and Quality of Strawberry Pircinque

In strawberry production, the combination of a high productive performance and fruits with desirable physicochemical characteristics requires the use of plants with a good quality and high initial vigor. This study aimed to evaluate the effect of plants with different crown diameters on the productive performance and fruit quality of strawberry plants of the cultivar ‘Pircinque’ (Short Day). The study was conducted in two evaluation cycles (2016/2017 and 2017/2018). The experimental design was divided into randomized blocks, with four repetitions, and plots consisting of 20 plants. This study evaluated the crown diameters of plants of 5, 7, 9, 11, 13, 15, 17, and 19 mm. The productivity and number of fruit values increased significantly by 57% with larger caliber plants, which also provided precocity of productivity. The use of more vigorous plants also favored the production of fruits with higher soluble solids/titratable acidity ratios (+28%) and with epidermis coloration closer to intense red (−4.3%). For the cultivar ‘Pircinque’, plant crown diameters between 15 and 17 mm are the most favorable because they condition the best productive performances in combination with precocity and a good fruit quality
