Características físicas dos frutos de quatro cultivares e duas seleções de goiabeira no 5º ano de produção em Porto Lucena - RS

Abstract: O trabalho foi conduzido em Porto Lucena, RS, na safra de 1992, com o objetivo de avaliar as características físicas dos frutos de 4 cultivares (IAC-4, Brune Vermelha, Riverside Vermelha e Pirassununga Vermelha) e duas seleções (RBS-1 e RBS-2) de goiabeira (Psidium guajava L.). As seleções RBS-1 e RBS-2 destacaram-se como as de maior peso médio de fruto e a seleção RBS-2 como a de maior diâmetro longitudinal (DL), diâmetro transversal (DT), relação DL/DT e peso da polpa (PP). A cv. Riverside Vermelha destacou-… Show more

“…A firmeza dos frutos é influenciada pelo estádio de maturação, condições climáticas durante o período de colheita e variabilidade genética (Paiva et al, 1995). A firmeza nos estádios iniciais de desenvolvimento da goiaba é devido à presença de substâncias pécticas as quais vão sendo degradas por ação enzimática proporcionando o amolecimento dos frutos (Huber, 1983).…”

“…Multiple breeding strategies on atemoya have included the use of polyline crosses between selected lines and commercial cultivars, interspecific crosses ( A. cherimoya , A. squamosa , A. reticulata , A. diversifolia , and atemoya) and auto‐tetraploid induction which have provided progeny for evaluation and advanced selections with specific characteristics to use for superior selection (George, Broadley, et al., 2002). Building on previous genetic diversity and inheritance research, selection criteria should include considerations of tree morphology, yield capacity, fruit quality, postharvest storage life characteristics and disease and pest susceptibility (Table 3) (George, Broadley, et al., 2002; Paiva & Fioravanço, 1994; Vanhove, 2008).…”

“…It is necessary to choose the best parents, based on available information, to carry out the required controlled cross‐pollinations (Table 2). The resultant hybrids with optimal characteristics must be vegetatively propagated to maintain their characteristics (Paiva & Fioravanço, 1994).…”

“…In Costa Rica, Laprade (1989) evaluated five soursop selections that had yields from good to excellent. Paiva and Fioravanço (1994) in Angola considered that there are two soursop types: a sweet, soft, low acidity, medium sized type that is used for fresh consumption and a sour type with high acidity and pulpy and fibrous flesh that is used for juice and sherbet production. The same authors mentioned that in Brazil, some selections had been made and introduced to commerce including types "A" and "B" from Bahia, and "Blanca," "Lisa," "Morada," and "FAO II" from Colombia.…”

“…A common objective for soursop improvement is for enhancing the opportunities through processing as the fruit has a short postharvest life and is susceptible to mechanical injury (Sánchez‐Nievas et al., 1953; Paiva & Fioravanço, 1994; Pinto & Andrade, 2005; Love & Paull, 2011; Lem et al., 2017). Processing cultivars and selections should have high yields (>20 t ha −1 ), regular production throughout the year without year‐to‐year variation, with excellent quality.…”
