| Significant initiatives exist within the global food market to search for new, alternative protein sources with better technological, functional, and nutritional properties. Lima bean (Phaseolus lunatus L.) protein isolate was hydrolyzed using a sequential pepsin-pancreatin enzymatic system. Hydrolysis was performed to produce limited (LH) and extensive hydrolysate (EH), each with different degrees of hydrolysis (DH). The effects of hydrolysis were evaluated in vitro in both hydrolysates based on structural, functional and bioactive properties. Structural properties analyzed by electrophoretic profile indicated that LH showed residual structures very similar to protein isolate (PI), although composed of mixtures of polypeptides that increased hydrophobic... |

| The objective of this study was to characterize for the first time polyphenols and DPPH (2-diphenyl-1-picryhydrazyl radical) antioxidant activity in commonly cultivated accessions of Phaseolus lunatus from an ex situ germplasm collection maintained by Embrapa, in Brazil. Furthermore, the study aimed to detect changes in total polyphenols, total flavonoids and condensed tannin for the same accessions after regeneration in a greenhouse. The results showed the diversity of the lima bean collection for phenolic compounds, which were strongly correlated with antioxidant activity. Lima beans accessions with the highest polyphenols and antioxidant activity were those with colored seeds. Conservation through cold storage of P. lunatus seeds in a cold chamber in... |

| ABSTRACT: This study evaluated the responses of lima bean (Phaseolus lunatus L.) to application of composted tannery sludge on nodulation, N uptake and plant growth. For eight years, the compost was applied at rates of: 0, 2.5, 5, 10, and 20 Mg ha-1 (dry basis). Plants of lima bean showed higher nodulation in treatments with compost; however, nodules reported in these treatments presented lower biomass, size and diversity than those reported in treatment without compost. Accumulation of N increased with the application of the highest rate (20 Mg ha-1), while there was an increase in chromium content in shoot with the increase in compost rates. Thus, the use of composted tannery sludge, in long-term, increases the accumulation of chromium in plants,... |

| ABSTRACT Cryopreservation is a technique used to preserve genetic material at ultra-low temperatures in cryogenic germplasm banks. In order to enable the cryopreservation of a seed, it is necessary to study its appropriate freezing temperature and its water content, because seeds reach maximum physiological quality with high water contents, and they tolerate drying when they are orthodox seeds, but they may not tolerate cryopreservation. Therefore, the objective of this study was to analyze the influence of initial water content (50 to 10% wet basis) on the kinetic behavior of the lima bean seed at the temperature of −150 °C, in addition to determining changes in its physiological quality (germination and vigor) when cryopreserved (−150 °C) for 30 days... |

| A podridão do colo, causada por Sclerotium rolfsii, é uma importante doença do feijão-fava (Phaseolus lunatus) no Nordeste brasileiro. O objetivo deste trabalho foi avaliar a reação de genótipos de feijão-fava a S. rolfsii, visando selecionar materiais com potencial de utilização no manejo da podridão do colo. Na primeira etapa, 50 genótipos de feijão-fava foram avaliados em relação a um isolado de S. rolfsii. Plantas com 10 dias de idade foram inoculadas pelo método de ferimento do colo e deposição do escleródio do patógeno. A incidência da doença foi avaliada 10 dias após a inoculação. A maioria dos genótipos (60%) se comportou como altamente suscetível ao patógeno, enquanto 36% foram classificadas como suscetíveis. Somente dois genótipos (F-2 e F-25) se... |

| The production of faba bean (Phaseolus lunatus) is limited due to the occurrence of Rhizoctonia canker, caused by the fungus Rhizoctonia solani. In order to select materials with potential for use in faba beans breeding programs and/or disease integrated management, 72 genotypes were evaluated and also stability of the disease resistance in relation to different pathogen isolates, inoculum densities and soil type. The seeds were sown in soil infested with the pathogen by the addition of colonized substrate (rice grains). The evaluation of genotypes was done after 15 days, using a note scale to discriminate the genotypes into five reaction classes. None of the 72 genotypes showed immunity to R. solani and only four genotypes (F-42, F-49, F-53 and F-58)... |

| O objetivo deste trabalho foi avaliar a produtividade da fava (Phaseolus lunatus L.) e descrever a morfologia de suas vagens e sementes. Oito variedades de fava (Amarela-cearense, Boca-de-moça, Branquinha, Mororó, Olho-de-ovelha, Olho-de-peixe, Orelha-de-vó, Raio-de-sol) foram avaliadas em experimento de campo no período de julho a dezembro de 1999, em Bananeiras, PB. Todas as variedades apresentaram hábito de crescimento indeterminado trepador e vagens compridas, de forma oblonga e recurvada, com número de sementes variando de duas a quatro. A variedade com vagens de maior comprimento (89,9 mm) e maior peso de 100 sementes (79,5 g) foi a Orelha-de-vó. As variedades Olho-de-ovelha e Orelha-de-vó apresentaram a maior e menor produtividade média de 0,852 e... |
