“…In Argentinean and Chilean transplants, 35-50 daughter plants per m 2 are maintained (PERTUZé et al, 2006). In the case of domestic nurseries, the average production is 100 transplants per m 2 (VERDIAL et al, 2009). higher density can cause competition for essential growth factors, such as nutrients, light and water, negatively affecting individual growth and resulting in less reserve accumulation (KIRSChBAUM et al, 2012).…”

-Obtaining high yields in strawberry crop requires the use of transplants with high sanitary and physiological quality. Thus, the present study aimed to evaluate the effect of the origin of strawberry transplants on quality, carbohydrate content and subsequent development and field production. Treatments covered four transplant origins: Argentina, Chile, Chuí (Rio Grande do Sul, Brazil) and São Francisco de Paula (Rio Grande do Sul, Brazil) and two cultivars (Camarosa and Camino Real) in experimental design of randomized blocks with four replicates, conducted between April and December 2010. Carbohydrate content in crown and roots was evaluated, as well as the growth and development of transplants and plant yield. Regardless of cultivar and origin of transplants, crown diameter values exceeding 8 mm were considered the minimum standard internationally established. Transplants propagated in Chui showed 100% mortality 20 days after planting, while losses were not recorded in Argentina and Chile transplants. Camarosa transplants from Chile showed the highest content of total soluble sugars in reserve organs, while higher starch content was obtained in Argentinean transplants. The high carbohydrate content in reserve organs in Argentina and Chile transplants led to greater fruit production. index terms: Fragaria x ananassa, bare root transplants, total sugar, yield. ConteÚdo de Carboidratos e desenvolvimento de mudas de moranGueiro de oriGem do rio Grande do sul e importadasresumo -A obtenção de elevadas produções na cultura do morangueiro é dependente da utilização de mudas com elevada qualidade sanitária e fisiológica. Assim, o presente estudo teve como objetivo avaliar a influência do local de origem das mudas de morangueiro, na qualidade, conteúdo de carboidratos e posterior desenvolvimento e produção a campo. Os tratamentos abrangeram quatro origens das mudas: Argentina, Chile, Chuí (Rio Grande do Sul, Brasil) e São Francisco de Paula (Rio Grande do Sul, Brasil) e duas cultivares (Camarosa e Camino Real), em delineamento experimental de blocos ao acaso, com quatro repetições, conduzido no período entre abril e dezembro de 2010. Avaliaram-se o conteúdo de carboidratos na coroa e nas raízes, o crescimento e o desenvolvimento das mudas e a produção das plantas. Independentemente da cultivar e da origem da muda, os valores de diâmetro da coroa foram superiores a 8 mm, considerado o padrão mínimo estabelecido internacionalmente. Mudas propagadas no Chuí apresentaram 100% de mortalidade aos 20 dias após o plantio, enquanto não foram registradas perdas nas argentinas e chilenas. Mudas de 'Camarosa', provenientes do Chile, apresentaram maior conteúdo de açúcares solúveis totais nos órgãos de reserva, enquanto maior teor de amido foi obtido em mudas argentinas. O maior conteúdo de carboidratos nos órgãos de reserva, em mudas argentinas e chilenas, reverteu em maior produção de frutas. termos para indexação: Fragaria x ananassa, mudas de raízes nuas, açúcares totais, produtividade.

El manejo hídrico del cultivo de fresa es uno de los principales problemas de producción en Colombia, reflejado en las perdidas de frutos o deformación de estos. Plantas de dos variedades de fresa (Fragaria x ananassa Duch), fueron irrigadas tanto en condiciones óptimas de riego como en déficit hídrico leve, en un macro túnel en la Sabana de Bogotá. Para el manejo hídrico se realizó el seguimiento durante cinco meses de variables climáticas (temperatura, humedad relativa, radiación PAR y déficit de presión de vapor) y del cultivo (temperatura del dosel, contenido de humedad de sustrato y conductancia estomática), buscando validar mediante la correlación de estos métodos conocidos el seguimiento del estado hídrico de las plantas de fresa mediante el método del índice de estrés hídrico del cultivo - CWSI. Se concluye que las imágenes termográficas mediante el CWSI son una herramienta válida y completa para la detección de estrés hídrico en cultivos protegidos de porte bajo, dada la alta correlación con otros métodos, y la ventaja que ofrece de relacionar el seguimiento de las características fisiológicas del cultivo con las variables climáticas que lo afectan.

“…In the present work, the average photosynthetically active radiation met the needs of the crop. High solar radiation makes the production and conversion of photoassimilates more efficient (Martinez-Ferri et al, 2016), which favours the production of fresh fruit matter (Rosa et al, 2013); dry matter in the crown, roots, leaves and stolons; and the accumulation of reserve substances (Verdial et al, 2009) and of sugars in the fruit.…”

Cultivation of strawberry in substrate: Productivity and fruit quality are affected by the cultivar origin and substrates

et al. 2018

The production and quality of strawberries may vary according to cultivar, transplant origin, and the system of plant cultivation. The objective was to evaluate the effect of different organic substrates and different transplant origins on strawberry production and fruit quality. The experiment was conducted in a randomized complete block design with a 2x2x4 factorial scheme using two cultivars (Albion and Camarosa) obtained from different origins (National-Brazilian and Imported-Argentine) and four combinations of substrates: (crushed sugarcane bagasse [70%] + organic compost [30%], crushed sugarcane bagasse [70%] + Carolina® commercial substrate [30%], burnt rice husks [70%] + organic compost [30%], and burnt rice husks [70%] + Carolina® commercial substrate [30%]). The experimental unit was composed of eight plants, with repetition in four blocks. The quality parameters of titrable total acidity, total soluble solids, ratio of sugar / acidity, firmness, and pulp coloration (chroma, hue angle, and L*, a* and b*) were evaluated, as were the production parameters of total number of fruits, total fruit production, average fruit mass, non-commercial fruit production, commercial fruit production and total productivity. The substrate influences the strawberry production variables. Fruit yield was highest in the Camarosa cultivar grown on the S3 substrate mixture. The cultivar, the transplant origin and the cultivation substrate influence fruit AT. SST and AT / SST are influenced only by cultivar and transplant origin. Chroma differs between plants with different transplant origins. Camarosa of National origin cultivated in burnt rice husks + organic compost presented the best production results and fruit quality.
