“…In the soilless production of tips for plug transplants, the growth of mother plant is not a matter of interest because mother plants should be discarded at the end of the tip production period. This would be an advantage only in the case that such plants were to be used for further production of fruit, as suggested by Dal Picio et al (2013). Nevertheless, these authors showed that, although high fruit yield can be reached by mother plants after tip production, fruit size is reduced.…”

“…In spite the existence of these studies on strawberry wild species, no similar records were found for the cultivated species Fragaria x ananassa. A vigorous growth of mother plants was reported during the propagation phase of this species for producing runner tips (Dal Picio et al, 2013), which represents a waste of carbon assimilates, water and mineral nutrients. Therefore, it can be hypothesised that defoliation can be used to reduce growth of mother plants, without reducing emission and growth of runner tips for plug transplant production.…”

-The objective of this work was to determine the sink-source relationships and their effects on the number and growth of runner tips of 'Camino Real' strawberry stock plants. Three types of sources were evaluated: one defoliation at 96 days after planting (DAP), two defoliations at 50 and 96 DAP, and mother plants without defoliation. Four types of sink were accessed: runner tips collected weekly and monthly, four stolons with rooted runner tips in pots, and four freely-grown stolons. A completely randomized experimental design was used in a split-plot arrangement, with four replicates. The source types were placed in the plots, and sink types in the subplots. The number of runner tips, the crown diameter, and the dry matter mass were determined. Number and growth of tips were higher on plants without defoliation, and decreased 44.7% on twice-defoliated mother plants. The two-defoliation management did not reduce runner tip dry matter mass only on plants with rooted stolons, which produced runner tips 50% heavier. Defoliation of mother plants bearing rooting stolons can be used to reduce their growth, without reducing the emission and growth of runner tips.Index terms: Fragaria x ananassa, plug plants, propagation, sink strength, source-sink relationship. Desfolha de plantas matrizes de morangueiro para a produção de pontas de estolãoResumo -O objetivo deste trabalho foi determinar as relações dreno-fonte e seus efeitos sobre o número e o crescimento de pontas de estolões de plantas matrizes de morangueiro 'Camino Real'. Três tipos de fontes foram avaliadas: uma desfolha aos 96 dias após o plantio (DAP), duas desfolhas aos 50 e 96 DAP e plantas matrizes sem desfolha. Quatro tipos de drenos foram analisados: pontas de estolão coletadas semanal e mensalmente, quatro pontas enraizadas em vasos e quatro estolões de crescimento livre. Utilizou-se o delineamento experimental inteiramente casualizado com parcelas subdivididas e quatro repetições. Os tipos de fonte foram dispostos nas parcelas, e os tipos de dreno, nas subparcelas. Foram determinados o número de pontas, o diâmetro de coroa e a massa de matéria seca. O número e o crescimento das pontas foram mais elevados nas plantas sem desfolhamento, e diminuíram 44,7% nas plantas matrizes com duas desfolhas. As duas desfolhas não reduziram a massa de matéria seca das pontas apenas nas plantas com estolões enraizados, as quais produziram pontas 50% mais pesadas. A desfolha das plantas matrizes com estolões enraizados pode ser usada para reduzir-lhes o crescimento, sem reduzir a emissão e o crescimento das pontas de estolão.Termos para indexação: Fragaria x ananassa, mudas em bandejas, propagação, força de dreno, relação fonte-dreno.

“…However, most strawberry plants used in the country have been imported from Patagonia (Argentina and Chile), due to excellent local growing conditions (Antunes and Peres, 2013;Gonçalves et al, 2016), which enable high resource (carbohydrate) accumulation (Cocco et al, 2016). This situation has made producers get increasingly dependent on plant importation and has obliged them to adapt cultivation to the period of plant arrival, which is often not the recommended one for growing strawberries in Brazil (Dal Picio et al, 2013).…”

Since dependence on seedling importation has been a hindrance to strawberry farmers, production of national plants has become an alternative solution. This study aimed at evaluating the field behavior of potted seedlings of strawberry plants in a low tunnel system in different early growing seasons in Rio Grande do Sul, Brazil. The experiment was carried out at Embrapa Clima Temperado in 2015 and 2016 in a randomized block design, composed of a 4x3 factorial, four cultivars (Aromas, Camarosa, Festival and Oso Grande) and three growing seasons (March 16th, April 1st and April 16th). For all seasons, the cultivation was until November 30 in 2015 and October 31 in 2016. The following variables were determined: beginning and full blooming, beginning and length of harvest; number of fruits; mean fruit mass; and fresh mass per plant throughout early and total production. The cultivar Aromas presents lower flowering uniformity among plants (difference between beginning and full flowering) according to the two years of evaluation. Potted strawberry seedlings planted until early April 1st - Season 2 in Pelotas, RS, allow high early production, with production above 400 grams per plant. The cultivar Camarosa when planted on March 16 or April 1 had total yield per plant above 800 grams. All cultivars under study (Aromas, Camarosa, Festival and Oso Grande) have better plant development and higher total yield gains in years with higher temperature and lower rainfall in the initial phase and good rainfall distribution over the growing season. (2015) than in years with most frequent precipitation and lower temperature in the initial phase and poor rainfall distribution over the growing season (2016).

“…No Brasil, são produzidas, aproximadamente, 150.000 toneladas da fruta, em uma área de 4.200 hectares (FAGHERAZZI et al 2017), e a produção é baseada em lavouras estabelecidas a partir de mudas de raízes nuas. As mesmas são produzidas a partir de pontas de estolão que são emitidas pela planta matriz e enraizadas diretamente no solo, sendo este o principal sistema de produção de mudas utilizado no país (DAL PICIO et al 2013).…”

Objetivou-se avaliar o desempenho agronômico de cultivares de morangueiro, a partir de mudas ‘plug plant’ produzidas com diferentes soluções nutritivas, em sistema de cultivo sem solo. Os experimentos foram realizados em casa de vegetação com a utilização de mudas das cultivares Aromas e Camarosa, as quais foram produzidas com quatro soluções nutritivas. Foram avaliados dois ciclos de cultivo. O primeiro, de abril de 2017 à março de 2018, foram avaliados o desempenho agronômico de duas cultivares (Camarosa e Aromas) e quatro soluções nutritivas (SN1, SN2, SN3 e SN4), em esquema fatorial 2 x 4. No segundo ciclo, de abril a dezembro de 2018, foram avaliadas duas cultivares (Camarosa e Aromas) e duas soluções nutritivas (SN3 e SN4), em esquema fatorial 2 x 2. Em ambos os ciclos, avaliaram-se variáveis fenológicas, produtivas e matéria seca de folhas, coroas e estolões. A utilização das diferentes soluções nutritivas na fase de produção dos propágulos não influenciou a maioria das variáveis analisadas, uma vez que o ciclo do morangueiro é longo e o efeito das mesmas acaba se diluindo no decorrer do mesmo. No entanto, o efeito do fator cultivar foi significativo, sendo que, no geral, ‘Camarosa’ foi mais precoce que ‘Aromas’ em relação às variáveis fenológicas referentes à floração, frutificação e estolonamento. As cultivares apresentaram produção de frutas similares entre si nos dois ciclos de cultivo. ‘Camarosa’ apresenta maior produção de matéria seca de folhas e estolões em comparação com a cultivar Aromas.
