O objetivo deste estudo foi realizar a caracterização físico-química da farinha de resíduos do despolpamento da feijoa (FRF) e verificar a potencialidade da sua utilização em biscoitos tipo cookies, por meio de propriedades tecnológicas e aceitação sensorial. A FRF foi obtida a partir da secagem a 55 °C e da moagem dos resíduos (endocarpo e mesocarpo) da feijoa, sendo caracterizada físico-quimicamente (composição centesimal, pH, ATT, carotenoides totais, ácido ascórbico e composição mineral) e utilizada na elaboração de cookies com substituição parcial de farinha de trigo (F1-10%FRF e F2-20%FRF), com posterior análise de características tecnológicas e teste de aceitação sensorial. A FRF se destacou em relação ao seu teor de fibra alimentar total (40,50 g/100g) e se mostrou uma importante e potencial fonte de elementos essenciais. Os cookies com FRF tiveram maiores médias de aceitação global, sendo que a amostra F2 apresentou o maior índice de aceitabilidade (88,17%). Todas as médias das notas atribuídas pelos provadores no teste de aceitabilidade, para as amostras F1 e F2, foram próximas de 8 na escala hedônica, demonstrando que os provadores “gostaram muito”. O teste de intenção de compra reproduziu a aceitabilidade dos provadores, sendo que as médias das notas para as amostras corresponderam a “certamente compraria” e “provavelmente compraria” na escala hedônica de intenção de compra. Os resultados obtidos neste estudo evidenciam a potencialidade da utilização da FRF, podendo contribuir para a diversificação da oferta de produtos, além de agregar valor ao resíduo do processamento de uma fruta nativa com potenciais características nutricionais.

Abstract: The objective of this work was to investigate the effect of liming and phosphorus fertilization on the growth, mineral composition of the leaves, fruit yield, and mycorrhizal colonization of young feijoa (Acca sellowiana) plants. Treatments consisted of four liming levels - 0, 25, 50, and 100% of the dose required to raise the soil pH to 6.5 - and of five levels of P - 0, 60, 120, 180, and 240 kg ha-1 P2O5 -, placed in a randomized complete block design, in a split-plot arrangement, with three replicates. The orchard was established in 2010 with the Helena cultivar. In 2012, 2013, and 2014, plant growth was evaluated by measuring trunk perimeter, plant height, and tree canopy width. Mineral composition of the leaves, regarding P, N, K, Ca, and Mg contents, was assessed annually. Mycorrhizal colonization was evaluated in 2012, and fruit yield was determined in 2014. No interaction was observed between the studied factors. P contents had no effect on the evaluated variables. Liming, however, increases plant growth, mycorrhizal colonization, fruit yield, and Ca and Mg leaf contents, besides reducing K leaf contents.

Thai basil (Ocimum basilicum L.) is widely cultivated in Malaysia and commonly used for culinary purposes. In March 2019, necrotic lesions were observed on the inflorescences of Thai basil plants with a disease incidence of 60% in Organic Edible Garden Unit, Faculty of Agriculture in the Serdang district (2°59'05.5"N 101°43'59.5"E) of Selangor province, Malaysia. Symptoms appeared as sudden, extensive brown spotting on the inflorescences of Thai basil that coalesced and rapidly expanded to cover the entire inflorescences. Diseased tissues (4×4 mm) were cut from the infected lesions, surface disinfected with 0.5% NaOCl for 1 min, rinsed three times with sterile distilled water, placed onto potato dextrose agar (PDA) plates and incubated at 25°C under 12-h photoperiod for 5 days. A total of 8 single-spore isolates were obtained from all sampled inflorescence tissues. The fungal colonies appeared white, turned grayish black with age and pale yellow on the reverse side. Conidia were one-celled, hyaline, subcylindrical with rounded end and 3 to 4 μm (width) and 13 to 15 μm (length) in size. For fungal identification to species level, genomic DNA of representative isolate (isolate C) was extracted using DNeasy Plant Mini Kit (Qiagen, USA). Internal transcribed spacer (ITS) region, calmodulin (CAL), actin (ACT), and chitin synthase-1 (CHS-1) were amplified using ITS5/ITS4 (White et al. 1990), CL1C/CL2C (Weir et al. 2012), ACT-512F/783R, and CHS-79F/CHS-345R primer sets (Carbone and Kohn 1999), respectively. A BLAST nucleotide search of ITS, CHS-1, CAL and ACT sequences showed 100% similarity to Colletotrichum siamense ex-type cultures strain C1315.2 (GenBank accession nos. ITS: JX010171 and CHS-1: JX009865) and isolate BPDI2 (CAL: FJ917505, ACT: FJ907423). The ITS, CHS-1, CAL and ACT sequences were deposited in GenBank as accession numbers MT571330, MW192791, MW192792 and MW140016. Pathogenicity was confirmed by spraying a spore suspension (1×106 spores/ml) of 7-day-old culture of isolate C onto 10 healthy inflorescences on five healthy Thai basil plants. Ten infloresences from an additional five control plants were only sprayed with sterile distilled water and the inoculated plants were covered with plastic bags for 2 days and maintained in a greenhouse at 28 ± 1°C, 98% relative humidity with a photoperiod of 12-h. Blossom blight symptoms resembling those observed in the field developed after 7 days on all inoculated inflorescences, while inflorescences on control plants remained asymptomatic. The experiment was repeated twice. C. siamense was successfully re-isolated from the infected inflorescences fulfilling Koch’s postulates. C. siamense has been reported causing blossom blight of Uraria in India (Srivastava et al. 2017), anthracnose on dragon fruit in India and fruits of Acca sellowiana in Brazil (Abirami et al. 2019; Fantinel et al. 2017). This pathogen can cause a serious threat to cultivation of Thai basil and there is currently no effective disease management strategy to control this disease. To our knowledge, this is the first report of blossom blight caused by C. siamense on Thai basil in Malaysia.

The South American fruit fly, Anastrepha fraterculus (Diptera: Tephritidae) stands out for its polyphagous habit of damaging the production of several fruits in southern Brazil. This study aimed to evaluate the capture efficiency of A. fraterculus using grape juice at different periods of decomposition and aging as well as to test the capture efficiency of the enzymatic hydrolyzed protein Cera Trap® in feijoa crops. The work was conducted in a commercial feijoa orchard in São Joaquim, SC, Brazil during the 2014 growing season. Undiluted Cera Trap®, fresh grape juice and grape juice that had aged for 7 and 14 days were evaluated. All of the treatments with grape juice were used at the recommended concentration of 25 %. McPhail traps were used with 300 mL for each lure. On a weekly basis, the number of adults and the percentage of female fruit flies captured were evaluated, using identification and counting. Cera Trap® was the lure that captured the highest number of fruit flies, with a high percentage of females and with a higher frequency of captures during the season. Cera Trap® also showed the highest number of action thresholds compared to grape juice treatments. The 25 % fresh and aged grape juice showed a low number of captures and a low number of action thresholds. We conclude that fresh and aged grape juice were not effective for capturing and  monitoring A. fraterculus in feijoa orchards. The Cera Trap® lure proves to be an alternative to improve  monitoring of A. fraterculus in orchards in southern Brazil.

ABSTRACT: The objective of this paper was to identify the direct and indirect effects of feijoa fruits (Acca sellowiana) traitson pulp weight, in order to use these traits in indirect genotypes selection. Fruits of five feijoa plants were collected in Rio Grande do Sul, in the years of 2009, 2010 and 2011. Six traits were evaluated: diameter, length, total weight, pulp weight, peel thickness and number of seeds per fruit. In the path analysis, with or without ridge regression, pulp weight was considered as the basic variable, and the other traits were considered as explanatory variables. Total weight and fruit diameter had high direct effect, and are the main traits associated with pulp weight. These traits may serve as criteria for indirect selection to increase feijoa pulp weight, since they are easy to be measured.

A feijoa (Acca sellowiana) é uma fruta nativa brasileira que é cultivada em vários países alem do Brasil, e que apresenta aproximadamente 30% do seu peso em polpa sendo o restante descartado. O objetivo deste estudo foi extrair e caracterizar a pectina da farinha do resíduo do processamento da feijoa e testar a sua aplicação na formulação de geleia empregando a polpa desta fruta. Empregou-se um delineamento composto central rotacional para extração da pectina e os fatores escolhidos para avaliar o rendimento de extração e o grau de metoxilação foram concentração de ácido cítrico (g.L-1) e temperatura de extração (ºC). As propriedades geleificantes foram analisadas por aplicação em geleias do tipo tradicional e Diet. Os resultados mostraram que o rendimento de extração variou entre 11,95 e 49,60 g.100 g–1, sendo o maior rendimento observado com 5 g.100 g–1 de ácido cítrico e 95 ºC. O grau de metoxilação variou entre 48,16% e 52,50%. A propriedade geleificante da pectina foi observada na elaboração de geleia do tipo tradicional, sendo que esta pectina foi caracterizada como sendo de alto grau de metoxilação.
