“…To vitamin C content, to control fruits in field assay, had gradual increased the ascorbic acid content during the ripening, from 35.34mg/100g in green fruits to 77.27mg/100g in red fruits, corroborating with Lee and Kader (2000) that showed the increase of ascorbic acid during ripening, and Lopes et al (2015), who showed about 70mg/100g of ascorbic acid in strawberry fruits in the red stage (Figure 2). However, with the exogenous application of brassinosteroid, there was reduction of the vitamin C content compared to control, at field assay to white fruits (20.71%), pink fruits (34.03%) and red fruits (26.09%) (Figure 2), while to postharvest assay white fruits with brassinosteroid treatment showed a 31.47% increase in vitamin C content compared to control.…”

“…Although involved in several aspects of plant growth, such as seed germination, cell elongation, root initiation, flower development and sexual determination, plant stress, maturation and senescence (MERCHANTE et al, 2013), ethylene is mainly known as "the ripening hormone" because of its known role in climacteric fruits (BAPAT et al, 2010). However, in non-climacteric fruits, such as strawberry, ethylene mediates few metabolic pathways, but, the role of this plant regulator has not yet been elucidated (LOPES et al, 2015;VILLARREAL et al, 2010). By the way ethylene is not the only plant regulator involved in the non-climacteric ripening, suggesting that it is also influenced by other plant growth regulators (MERCHANTE et al, 2013) as Abscisic acid (AYUB et al, 2016) and brassinosteroids (AYUB et al, 2018).…”

-In contrast to ripening of climacteric fruits knowledge, non-climacteric fruits ripening still poorly understood. In this sense, strawberry (Fragaria x ananassa L. Duch) is a high commercial crop and has an expressive world production that has been used as a model study. Thus, the aim of this study was to evaluate the effect on physicochemical and phytochemical characteristics of strawberry Cv. Camiño Real, in four maturation stages (green, white, pink and red) after the ethylene (Etephon®) and brassinosteroid (epi-brassinolide) exogenous spray. The evaluations were carried out at application time (field assay) and after 24h (post-harvest assay). Brassinosteroid application tends to reduce phenolic compounds content mainly in the red stage, whereas ethylene treatment tends to increase supposing that while brassinosteroids reduce phenolic compounds acting to fruit conservation, by the reduction of oxidative stress, increasing antioxidant activity, the ethylene act in fruit ripening leading to senescence. However, for vitamin C content while brassinosteroid treatment increases ascorbic acid in postharvest for the white fruit, the ethylene treatment do a dramatically increased in vitamin C content to red fruits, showing that although ethylene and brassinosteroids can affect the vitamin C content, the response can change according to the development stage spray, suggesting that more studies are necessary to understand the hormonal interaction for ascorbic acid production during strawberry ripening.

Efeito do etileno e do brassinoestereoide no amadurecimento do morango após aplicação no campoResumo -Em contraste com o conhecimento sobre a maturação de frutos climatéricos, a maturação de frutos não climatéricos ainda é pouco entendida. Neste sentido, o morangueiro (Fragaria x ananassa) é uma cultura de elevado valor comercial e expressiva produção mundial que vem sendo utilizada como modelo de estudos. Assim, o objetivo deste trabalho foi avaliar o efeito sobre as características físico-químicas e fitoquímicas do morango Cv. Camiño Real, em quatro estádios de maturação (verde, branco, rosa e vermelho), após o spray exógeno de etileno (Etephon®) e brassinoesteroide (epibrassinolide). As avaliações foram realizadas no momento da aplicação (ensaio de campo) e após 24 h (ensaio pós-colheita). A aplicação de brassinoesteroide reduz o conteúdo de compostos fenólicos no estádio vermelho, enquanto o tratamento com etileno aumenta. Assim, supõe-se que, enquanto os brassinoesteroides diminuem a concentração de compostos fenólicos, atuando na conservação dos frutos pela redução do estresse oxidativo e pelo aumento da atividade antioxidante, o etileno age acelerando o amadurecimento do fruto, levando à senescência. No entanto, para o conteúdo de vitamina C, enquanto o tratamento com brassinoesteroide aumenta o ácido ascórbico na pós-colheita em frutos brancos, o tratamento de etileno aumentou dramaticamente o conteúdo de vitamina C ...

“…belong to the family Rosaceae, and are a crop of economic importance that is highly appreciated worldwide for its organoleptic characteristics and health benefits (Lopes et al, 2015). Strawberries are grown in temperate and subtropical climate regions in Brazil, and are mainly produced on small farms for either in natura consumption or subsequent processing (Witter et al, 2012).…”

ABSTRACT. Most strawberry genotypes grown commercially in Brazil originate from breeding programs in the United States, and are therefore not adapted to the various soil and climatic conditions found in Brazil. Thus, quantifying the magnitude of genotype x environment (GE) interactions serves as a primary means for increasing average Brazilian strawberry yields, and helps provide specific recommendations for farmers on which genotypes meet high yield and phenotypic stability thresholds. The aim of this study was to use AMMI (additive main effects and multiplicative interaction) and GGE biplot (genotype main effects + genotype x environment interaction) analyses to identify high-yield, stable strawberry genotypes grown at three locations in Espírito Santo for two agricultural years. We evaluated seven strawberry genotypes (Dover, Camino Real, Ventana, Camarosa, Seascape, Diamante, and Aromas) at three locations (Domingos Martins, Iúna, and Muniz Freire) in agricultural years 2006 and 2007, totaling six study environments. Joint analysis of variance was calculated using yield data (t/ha), and AMMI and GGE biplot analysis was conducted following the detection of a significant genotypes x agricultural years x locations (G x A x L) interaction. During the two agricultural years, evaluated locations were allocated to different regions on biplot graphics using both methods, indicating distinctions among them. Based on the results obtained from the two methods used in this study to investigate the G x A x L interaction, we recommend growing the Camarosa genotype for production at the three locations assessed due to the high frequency of favorable alleles, which were expressed in all localities evaluated regardless of the agricultural year.

“…The finding was confirmed by Villareal and colleagues (2016) who described the response to ethylene of several strawberry cell-wall metabolic genes. It has also been extensively reported that ethylene treatment elicited anthocyanins accumulation in ripening strawberry (Ku et al, 1999;Bower et al, 2003;Villarreal et al, 2010;Merchante et al, 2013;Sun et al, 2013;Lopes et al, 2015). In addition, Sun and colleagues (2013) demonstrated that the expression of FaSAMS1(S-adenosyl-L-methionine synthase 1) and FaCTR1 (constitutive triple response 1) genes played a significant role in the softening and red-color development of strawberry fruit.…”

Continuous Exposure to Ethylene Differentially Affects Senescence in Receptacle and Achene Tissues in Strawberry Fruit

et al. 2020

Strawberry shelf life is limited, and little is known about the postharvest regulation of senescence in different fruit tissues. Strawberry is classified as a non-climacteric fruit, yet it is known that ethylene affects strawberry ripening. Here the effects of continuous exogenous ethylene (50 µl l −1) were investigated in cold stored strawberry (5°C). The physiological and biochemical responses of ripe strawberry were evaluated across 6 days, together with hormonal profiles of the whole fruit and individual tissues (achenes and receptacle). Continuous exposure to ethylene induced as a first response an accumulation of abscisic acid (ABA) in the receptacle tissue, followed by an increase in CO 2 production. Ethylene also elicited sucrose hydrolysis and malic acid catabolism, with the major effect seen after 4 days of ethylene exposure. Additionally, accumulation of phenolics (epicatechin and chlorogenic acid) were also observed in ethylene treated strawberry. Achenes did not exhibit a response to ethylene, yet catabolism of both ABA and auxins increased by two thirds during air storage. In contrast, ethylene induced ABA accumulation in the receptacle tissue without ABA catabolism being affected. This hormonal disequilibrium in response to ethylene between the two tissues was maintained during storage, and therefore might be the precursor for the following biochemical variations reported during storage.
