“…In this context, the resumption of shoot and root growth is dependent on the amount of carbohydrates stored in reserve organs. As the plant subsequently produces new leaves, flowers and crowns, yield becomes more dependent on the photosynthetic capacity and the plant growth rate (EShGhI et al, 2007). Palha et al (2002) observed positive correlation (r = 0.73) between early fruit production and carbohydrate concentration in roots, emphasizing its importance for the establishment and growth of strawberry transplants.…”

“…Low temperatures are associated with the reduction of plant respiration and, consequently, with lower energy expenditure and increase in liquid photosynthesis (EShGhI et al, 2007). As far as floral induction is concerned, the thermal amplitude between day and night is one of the most important environmental factors (SONSTEBY et al, 2013).…”

“…Carbohydrates stored in the reserve organs play a fundamental role in the recovery of plant growth after transplantation, as well as in the production of the first flowers and fruits (ESHGHI et al, 2007). These physiological processes are dependent on the accumulated reserves until the plant acquires autonomy in energy production and supply (BARTCZAK et al, 2010).…”

-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.

“…Furthermore, flower bud differentiation and development require large quantities of carbohydrates (Peng and Iwahori, 1994). The soluble carbohydrates content in shoot tips, leaves, and roots of June-bearing strawberries may play an important role in flower bud differentiation (Eshghi et al, 2007). Therefore, the increase in the number of flowers in the first and second inflorescences of plants cultivated under supplemental lighting should be resulted from the greater allocation of carbohydrates to bud primordia.…”

The aim of this study was to determine the optimum photoperiod of supplemental lighting to obtain high fruit yields in forcing culture of strawberry. Strawberry plants were illuminated with supplemental lighting provided by high-irradiance light-emitting diodes with photoperiods of 24, 16, 14, or 12-h daily under the controlled air temperature conditions set the ventilation starting temperature at 26°C and minimum air temperature at 6°C from October to May. Compared with plants in the other treatments and the control, those in the 12-h photoperiod treatment showed a significant increase in leaf photosynthesis and earlier differentiation of flower buds on the second inflorescence. These physiological changes resulted in the large amounts of carbon translocation from leaf to fruit, leading to the fruit quality improvement and the highest marketable yield among all of the treatments. When the photoperiod of supplemental lighting exceeded 12 h per day, flower opening on the first inflorescence was accelerated, but flower bud initiation on the second inflorescence was inhibited. This inhibition caused a decrease in leaf photosynthesis, leading to excessive carbohydrate accumulation in the leaves, resulting in lower total fruit yield than that from plants in the 12-h photoperiod treatment. These data show that a 12-h photoperiod of supplemental lighting is appropriate to obtain high yields in forcing culture of strawberry.

“…Soluble sugars and sorbitol were analyzed as previously described (Eshghi et al, 2007) (Singh et al, 2019). Consistently with these data, GA application increases bud break and cell permeability in hybrid aspen by inducing 1,3-β-glucanase genes that break down callose in order to open plasmodesmata sphincters (Rinne et al, 2011); and poplar transgenic plants with modified GA metabolism and signaling show altered bud set, bud break and flowering (Zawaski et al, 2011).…”
