Abscisic acid (ABA) plays an important role in regulating activities of antioxidant enzymes, hormone levels, accumulation of reactive oxygen species under stress. To understand the effects of exogenous ABA treatment on flooding tolerance at seedling stage in adzuki bean (Vigna angularis), the water-sensitive (WS) variety ‘Tianjinhong’ (TJH) and the water-tolerant (WT) variety ‘Longxiaodou 4’ (LXD 4) were foliar sprayed exogenous ABA with 20 μM, followed by flooding stress for 5 days under pot conditions. Our results revealed that under flooding stress at seedling stage, the contents of H2O2 and MDA, proline and soluble protein in adzuki bean leaves significantly increased, the contents of ABA, IAA and SA significantly increased, and the activities of SOD, POD and CAT also significantly increased. Flooding treatment for 5 days resulted in a significant decrease in single pot yield of LXD 4 by 8.40% and TJH by 9.91%. Foliar spray of 20 μM exogenous ABA could resist flooding stress, considerably increased the contents of proline and soluble protein, significantly decreased the contents of H2O2 and MDA, significantly increased the activities of SOD and POD, increased the contents of ABA and SA, and significantly inhibited the increase of IAA content in adzuki bean leaves. Spraying exogenous ABA significantly increased the yield of ‘LXD’ 4 by 6.95% after 4 days of flooding treatment, and ‘TJH’ by 4.46%. To sum up, there were significant differences in physiological stress among different varieties of adzuki bean under flooding stress, and spraying exogenous ABA could effectively alleviate the effects of flooding stress on physiology and yield of adzuki bean. The results of this study provided a theoretical basis for further studying the physiological mechanism of adzuki bean resisting flooding stress at seedling stage and improving the yield of adzuki bean under flooding stress. Thus, foliar spraying exogenous ABA effectively improved submergence tolerance by enhancing the activity of protective enzymes and osmoregulation. These results provided novel insights and were expected to aid in the development of more effective stress resistance cultivation methods in adzuki bean production.

Abstract This research aims to evaluate the use of different filler levels of taro meal on the physical quality of chicken patties containing red beans (Vigna angularis). Patties produced from chicken meat with the ratio of red bean flour and taro flour as filler substitution for tapioca flour are 15:0 (CP0), 15:3 (CP1), 10:0 (CP2), 10:3 (CP3), 5:0 (CP4), and 5:3 (CP5). The analysis showed a significant difference in the tenderness (P<0.01), the value of pH, cooking loss, and water holding capacity (P<0.05) of patties. The addition of taro flour can increase the tenderness value of chicken patties. Reducing the amount of red beans resulted in a decrease in the pH value of chicken patties, but the increase in the use of taro meal did not result in a difference in the pH value. The highest cooking loss was achieved with the use of 5% red beans without taro meal. The highest water holding capacity of patties produced was obtained with a ratio of red bean and taro meal of 5:3. The conclusion is that adding 10% red beans and 3% taro flour red beans increased the physical quality of chicken patties and can be accepted by consumers.

Seed coat colour is an important nutritional quality trait. Variations in anthocyanins and flavonoids induce the diversity of seed coat colour in adzuki bean (Vigna angularis L.). Red seed coat and black seed coat are important adzuki bean cultivars. Insights into the differences of flavonoid metabolic pathways between black and red adzuki bean are significant. In this study, we explored that the difference in seed coat colour between the red (Jingnong6) and the black (AG118) is caused by the accumulation of anthocyanins. The RNA-sequencing (RNA-Seq) and real-time reverse transcription (qRT)-PCR results showed that the Vigna angularis L. seed coat color (VaSDC1) gene, an R2R3-MYB transcription factor, should be the key gene to regulate the black and red seed coat colours. In three different colouring staes of seed development, VaSDC1 was specifically expressed in the black seed coat (AG118) landrace, which activates the structural genes of flavonoid metabolic pathways. As a result, this caused a substantial accumulation of anthocyanins and created a dark blue-black colour. In the red (Jingnong6) seed coat variety, low expression levels of VaSDC1 resulted in a lower accumulation of anthocyanins than in AG118. In addition, VaSDC1 was genetically mapped in the interval between simple-sequence repeat (SSR) markers Sca326-12, Sca326-4, and BAgs007 on chromosome 3 using an F4 segregating population derived from the cross between Jingnong6 and AG118. These results will facilitate the improvement of nutritional quality breeding in adzuki beans.

Sprout is a nutritious ready-to-eat vegetable. In this study, we examined the effects of ultrasonication treatments (treated with 28, 40 or 80 kHz frequency for 10 min at 25 °C) on the changes in microstructure, seed hydration and germination, sprout growth, sprout quality, and microbial load of two adzuki bean (Vigna angularis) varieties (Kaohsiung 8 and Kaohsiung 10). The results indicated that the ultrasonication at 40 kHz or 80 kHz improved seed hydration and enhanced germination; this is linked to the ultrasound-induced microstructure changes in the hilum and seed coat surface of treated seeds. The ultrasonication-increased sprout growth and yield were possibly attributable to the increased α-amylase activity during germination. Ultrasonication also improved total polyphenols, total flavonoids, and total saponins contents and further enhanced the anti-oxidative activities (FRAP and DPPH) of produce sprouts. The results further indicated that the 40 kHz or 80 kHz treatment decreased microbial loads of treated sprouts to an acceptable level; therefore, these two treatments can be used for germination improvement and an effective microbial control treatment for adzuki bean sprout production.

A determinação de propriedades físicas de grãos possui grande importância em diversas etapas do processo de beneficiamento, como o dimensionamento de equipamentos e sistemas para colheita, manuseio, transporte, secagem e armazenamento. Este trabalho teve como objetivo avaliar as características físicas do feijão azuki em função da influência da alteração do teor de água do grão. Os grãos de feijão azuki apresentaram teor de água inicial de 10%, buscando faixas de diferentes teores de água, os grãos foram submergidos em água em diferentes proporções e armazenados em estufa incubadora B.O.D para evitar contaminação, por 24 horas, obtendo assim teor de água de 15% e 20%. Os grãos foram caracterizados fisicamente pelas análises de teor de água, atividade de água, massa especifica aparente, massa específica real, porosidade, massa de mil grãos, volume do grão, ângulo de repouso estático e dinâmico, dimensões (a, b, c) e esfericidade. A análise estatística foi feita através do software Statistica 7.0, onde os resultados obtidos foram avaliados por análise de variância (ANOVA) e as médias foram comparadas pelo teste de Tukey a 5% de probabilidade. Após execução das análises foi possível observar variações significativas na maioria dos parâmetros avaliados, com aumentos ou diminuições dos valores de forma coerente e proporcional ao seu respectivo aumento do teor de água. Todos os parâmetros com exceção da dimensão do grão apresentaram diferença significativa nos seus valores pelo menos com uma variação do teor de água.
