“…Apparently, gibberellin affects the anthocyanin content in the fruit, depending on the applied amount (Souza et al 2017). Rosso & Mercadante (2007) affirm that anthocyanins may condense with vitamin C and promote an accelerated degradation of these compounds.…”

Floral management using the growth regulator paclobutrazol may be an alternative for promoting the uniformity of flowering and fruiting in West Indian cherry (Malpighia emarginata D.C.) plants. However, the effects of its use on fruit quality are still unknown. This study aimed to evaluate the effect of paclobutrazol doses on the fruit quality of M. emarginata. The experimental design was randomized blocks, in a 2 x 5 factorial arrangement, with three replications and three plants per plot, with the studied factors consisting of two M. emarginata cultivars ('Junko' and 'Flor Branca') and five paclobutrazol doses (0, 0.4, 0.8, 1.2 and 1.6 g a.i. m-1 of canopy diameter). The following variables were evaluated: fruit mass, fruit transverse and longitudinal diameters, pH, soluble solids content, titratable acidity, soluble solids/titratable acidity ratio and vitamin C content. The use of paclobutrazol, to some extent, promoted the increase of fruit mass, longitudinal diameter and soluble solids contents. The 'Junko' cultivar presented a higher vitamin C content than that for 'Flor Branca', and the maximum vitamin C contents were obtained with the paclobutrazol doses of 0.64 and 0.81 g a.i. m-1, respectively for the 'Junko' and 'Flor Branca' cultivars. None of the studied factors promoted differences for pH and fruit acidity.

“…Acerola is a very fragile and perishable fruit mainly due to the accelerated loss of esh rmness during ripening (Carrington and King, 2002;Quoc et al, 2015;Souza et al, 2017), which has been reported to be associated with increasing activity of cell wall degrading enzymes and loss of cellular turgor pressure (Santos et al, 2019). Indeed, ripe acerolas have lower esh rmness, compared to other fruit species (Batista et al, 2015), making the fruit more susceptible to mechanical damage and losses.…”

“…The genotype PROG 069 ranked fourth in both growing seasons, according to the selection index. One of the most important quality traits observed in the genotype PROG 069 was the high fruit esh rmness, which increases resistance to mechanical damage and postharvest live of the fruit (Quoc et al, 2015;Souza et al, 2017).…”

Multivariate selection index of acerola genotypes for fresh consumption based on fruit physicochemical attributes

et al. 2022

Acerola (Malpighia emarginata DC.) is one of the most important fruit produced in the São Francisco Valley, a Semi-arid region in the Northeast of Brazil. This study aimed to evaluate the physicochemical quality of thirty-ve acerola genotypes produced during two growing seasons in a Semi-arid region and to identify the best ones with potential for fresh consumption based on a multivariate selection index. Fruit of each genotype were harvested during two growing seasons at the maturity stage red-ripe, characterized by full red skin color. After harvest, the fruit were evaluated for diameter, mass, esh rmness, soluble solids (SS), titratable acidity (TA), SS/TA ratio, ascorbic acid content and skin color. A multivariate selection index (SI) was applied for scoring and ranking the genotypes for fresh consumption based on red-ripe fruit physicochemical quality. According to the results, all physicochemical attributes had high variability among genotypes. The SI was a powerful tool for identifying genotypes with high potential for fresh consumption, since it allowed selecting genotypes with multiple desirable traits. In the rst and second growing seasons, the SI identi ed the genotypes PROG 052 (SI = 76.1 and 78.9), BRS Rubra (SI = 74.1 and 99.5), Cabocla (SI = 72.3 and 70.7), Costa Rica (SI = 61.2 and 73.8) and PROG 069 (SI = 68.1 and 72.4) as the most promising ones for fresh consumption due to the presence of multiple desirable traits such as high diameter, mass, esh rmness, SS, and SS/AT ratio, as well as lower acidity. IntroductionAcerola (Malpighia emarginata DC.) is a tropical super-fruit due to its high vitamin C content that exceeds 100 times the contents observed in oranges and lemons (Prakash and Baskaran, 2018). The worldwide cultivation of acerola takes place from South Texas, Mexico, Central America and Northern regions in the South America, as well as some regions of Southeast Asia, specially India (Assis et al., 2008;Hanamura et al., 2008). Currently, Brazil is the largest producer of acerola, with several cultivation areas in the Northeastern region, where the environmental conditions enable three to four harvests per year (Alves et al., 1999).The production of acerolas in Brazil is intended for the fresh fruit market and/or processing industry. Genotypes intended for fresh consumption are characterized by larger and rmer fruit, with higher soluble solids content and lower levels of organic acids, which guarantees the sweetness desired by consumers (Hoehn et al., 2005). On the other hand, genotypes intended for the processing industry must have higher levels of ascorbic acid, which is one of the main forms of processed products. Acerola can also be marketed as frozen pulp, concentrate, juice, ice cream, gelatin, soft drinks, nectar, jelly, gum, preserve, yogurts and sodas (Delva and Schneider, 2013;Mezadri et al., 2006).The quality of each acerola genotype is highly dependent on environmental conditions such as temperature, precipitation and sunlight, as well as on crop management practices such as ir...

“…SegundoCarpentieri-pipolo et al (2000) frutos grandes que possuem um maior diâmetro geralmente são os que apresentam uma maior quantidade de polpa sendo esse um fator favorável a seleção. No estudoSouza et al (2017) destacaram características importantes consideradas determinantes na qualidade pós colheita das acerolas, como a cor que está diretamente associado a concentração de pigmentos que na acerola tem predominância as antocianinas. Outro parâmetro físico importante é a firmeza, que está relacionado com estrutura das paredes celulares e sua integridade, ressaltando que frutos com alta firmeza possui uma vida útil pós colheita mais prolongada.…”

RESUMOO Brasil é considerado mundialmente um dos maiores produtores de acerola, devido suas condições climáticas, apresenta condições ideais para o cultivo desta fruta. Esse trabalho, por meio da revisão de literatura, teve o objetivo de identificar a produção científica que abordasse a temática de melhoramento genético e seleção de clone de aceroleira com propriedades superiores, destacando a relevância do tema. Os dados foram obtidos através da busca eletrônica nas bases de dados LILACS, PubMed, ScienceDirect, Periódicos da Capes e biblioteca eletrônica SciELO. Após a identificação dos artigos científicos, foram realizadas as seguintes etapas de seleção, a leitura criteriosa dos títulos, dos resumos e na íntegra. A amostra desta revisão consistiu em 9 estudos onde mostrava que predominantemente as técnicas mais usadas para identificar os melhores clones de aceroleira ou aqueles com características superiores ocorria por meio da análise de parâmetros dos frutos: diâmetro transversal, diâmetro lateral, textura, índice de formato do fruto, peso médio por fruto, peso da polpa, peso da semente, coloração da casca e índice de maturação. Assim como através da análise do potencial agronômico da planta: altura de planta (AP) diâmetro da copa (DC), crescimento total em 20 ramos e crescimento médio de ramos, produção de frutos. Os programas de melhoramento genéticos visam manter a qualidade dos frutos bem como uma produção uniforme, tendo em vista que esses padrões podem ser alcançados com o uso de clones com genes superiores. Foi possível observar a importância da realização de estudos de cruzamento de clones de aceroleira e avaliação dos seus parâmetros físico-químico e agronômico pois auxiliam na formação de novos pomares que produzam frutos que atendam às exigências das indústrias.
