| Several extraction methods of genomic DNA for identification and characterization of genetic diversity in different plant species are routinely applied during molecular analysis. However, the presence of undesirable compounds such as polyphenols and polysaccharides is one of the biggest problems faced during the isolation and purification of high quality DNA in plants. Therefore, achievement of fast and accurate methods for DNA extraction is crucial in order to produce pure samples. Leaves of strawberry genotypes (Fragaria ananassa) have high contents of polysaccharides and polyphenols which increase the sample viscosity and decrease the DNA quality, interfering with the PCR performance. Thereby, in this study we evaluated the quality and amount of genomic... |

| Este trabalho apresenta a primeira contribuição ao estudo de biologia e tabela de vida de fertilidade de Aphis forbesi, Weed, 1889 (Hemiptera: Aphididae), uma importante praga de morangueiro no mundo. Esta espécie se desenvolve na coroa e pecíolo do morangueiro. O desenvolvimento desta espécie em laboratório apresentou dificuldades, possivelmente devido à protocooperação com formigas, observada em campo durante coletas. O ciclo de vida de A. forbesi foi estudado em folhas de morangueiro cultivar ‘Albion’ a 25 ± 2 °C, 60 ± 10% umidade relativa, e fotofase de 12 horas. O experimento foi inteiramente casualizado com 100 repetições. Os parâmetros da tabela de vida de fertilidade foram calculados usando o software TabVida. Na população estudada observou-se que... |

| The objective of this work was to evaluate the influence of cell sizes used for strawberry plug production in trays compared to bare root transplants, regarding initial plant size, harvest timing, and total strawberry fruit yield. Plug transplants were produced from runner tips rooted in trays with cell sizes of 26.5, 50, 100 and 150 cm³ filled with Plantmax HA organic substrate. Bare root transplants (control) were produced in a closed soilless system using sand as substrate. A randomized block design was used, with four replicates with 16 plants per plot. Bare root transplants and plug transplants from 100-cm³ cells had larger crown and higher leaf and root dry mass. Early fruit yield was higher in plants propagated from plugs than in those propagated... |

| Objetivou-se, neste trabalho, avaliar as modificações da poligalacturonase (PG) e da pectinametilesterase (PME) em morangos cultivados na região de Lavras, MG, e armazenados em temperatura ambiente. Foram utilizados morangos das cultivares 'Oso-grande', 'Toyorrinho' e 'Tudla'. Utilizou-se o delineamento inteiramente casualizado com 4 repetições, sendo os tratamentos arranjados em esquema fatorial (3X2), sendo 3 cultivares e 2 dias de análises (0 e 5 dias). A parcela experimental foi constituída por 10 frutos. Durante o armazenamento houve uma diminuição nos teores de pectina total e um aumento nos de pectina solúvel em todas as variedades analisadas. A atividade da PG e PME aumentaram com o período de armazenamento, independente da cultivar. |

| ABSTRACT In intensive hydroponic systems, such vertical and pyramidal systems, photosynthetically active radiation (PAR) and integrated (IPAR) may be intercepted by the containers and the leaf area of the plants grown in the upper strata, decreasing fruit yields and quality. The objective of this study was to evaluate the behavior of PAR and IPAR at different planting heights and the effect of geographic orientation and fruit yield and quality of strawberry produced in stair-like containers. The factors were four heights of the container (0.20, 0.50, 0.80 and 1.10 m) and two orientations (east and west). At each height and orientation of the container, PAR and IPAR, yield and fruit total soluble solids were measured. PAR and IPAR were statistically... |

| Abstract The lack of programs to improve the strawberry crop in Brazil has led to a growing increase in the use of seedlings imported from Chile, which leads to a certain dependence of imported material on the part of the producers and increases the production even more, since the producers have. This proves even more the need for the development of cultivars adapted to the local conditions of cultivation. In this sense, the aim was to evaluate the post-harvest of fruits of 15 hybrids of strawberry obtained from the cross between commercial cultivars, in order to select the materials with chemical quality superior to the cultivars most planted in Brazil. The contents of soluble solids, titratable acidity, ratio, vitamin C, anthocyanins and phenol were... |

| ABSTRACT Strawberry is a crop of great economic and social importance. Its fruits are appreciated both for their flavor and nutraceutical potential. Some studies confirm that light quality influences plant physiology. Thus, the aim of this study was to investigate if changes in light spectrum, provided by low tunnels, can improve vegetative traits, as well as, production and fruit quality of strawberry. The authors used six tunnel covers (red, yellow, blue, green, transparent and opaque and one control, without cover), and two cultivars: a short photoperiod cultivar (Camarosa) and a neutral photoperiod cultivar (Albion). Experiment was evaluated in two seasons: production and plant development first; and then, post-harvest quality. Overall, Camarosa showed... |

| ABSTRACT: In recent years "redness" has increasingly appeared in strawberry plants with leaves taking on a reddish color. No causal agent has been associated with plants. Since strawberries presented problems due to the incidence of nematodes, the purpose of this study was to look at the relationship between production, resistance to the Meloidogyne hapla nematode and the "redness" symptom in strawberry cultivars. Two experiments were performed, both with the 'Camino Real', 'Festival', 'Oso Grande', 'Albion' and 'Camarosa' cultivars. The first experiment was performed in the field, where the following were evaluated: strawberry production, fruit quality, macro and micronutrient contents in fruit and leaves, percentage of plant survival, incidence of... |

| ABSTRACT Strawberry production in the south part of Rio Grande do Sul has already been consolidated and, recently, this production has undergone several changes in its cultivation system. The profile of the strawberry producers in this region, and the cultivation systems they use, considering socioeconomic and technological characterization, had not been formally studied since then. This study aimed to characterize the socioeconomic profile of producers, as well as the strawberry production system. Data were obtained through a questionnaire, with questions related to the socioeconomic aspects of the producers and the technical aspects of their cultivation systems. Most of the interviewed producers are male, 26-50 years old, owing up to 20 hectares land,... |
