Abstract: El objetivo del presente trabajo fue evaluar sensorialmente el frijol común mejorado nutricionalmente (línea 38) y la variedad local (BAT 304) con productores y consumidores de dos comunidades de Holguín, Cuba. Se aplicó una encuesta exploratoria que determinó el alto consumo de los frijoles negros peque os, y las recetas: arroz con frijoles y potaje. Se seleccionó una muestra de 80 personas y se aplicaron tres pruebas entre marzo y junio del 2008: discriminatoria triangular, aceptabilidad y preferencia. Se encontró que 50 personas discriminaron correctamente entre las dos variedades (P<0,000001). No hubo diferencia significativa (P=0,9) en el porcentaje de participantes que clasificaron (en una escala de uno a cuatro) la consistencia del caldo, el sabor del potaje y la textura del grano entre las variedades; sin embargo, al calificar estas características con palabras, notaron una diferencia en consistencia y textura, mas no en el sabor del potaje elaborado con los dos tipos de frijol. Finalmente, siete evaluadores no indicaron una preferencia por el potaje elaborado con uno u otro tipo de frijol. De los 73 que sí expresaron una preferencia, no manifestaron diferencia estadísticamente importante (P=0,13). En conclusión, existió diferencia sensorial entre los frijoles, pero la preferencia fue similar, lo que sugiere una buena aceptación del consumidor por el frijol mejorado nutricionalmente.

Abstract: sensory evaluation of nutritionally improved beans (phaseolus vulgaris l.) in two cuban communities. the objective of this study was to evaluate the sensory characteristics of nutritionally improved common bean (line 38) and a local varie ty (bat 304) among bean producers and consumers in holguín, cuba. an exploratory questionnaire revealed that small-seeded black beans were the most consumed, and that rice and bean casserole were the main recipes. three sensory tests were applied to 80 individuals from march to june 2008: triangle discrimination, acceptability, and preference. fifty participants correctly discriminated between the two bean varieties (p<0.000001). there was no statistical difference (p=0.9, on a scale of 1 to 4) in the number of participants who classified broth consistency, the taste of the casserole, and the texture of the beans. however, when words were used to describe and score these characteristics, there was a difference between the bean varieties in consistency and texture, but not in broth taste. seven participants indicated no preference for the casserole prepared with either bean. of the remaining 73 that expressed a preference, there was no statistical difference (p=0.13) in the proportion who preferred any bean type. in conclusion, there are sensory differences between the nutritionally improved and locally consumed beans, but preference was similar, which suggests good consumer acceptance of nutritionally improved beans.

Abstract: objective: agronomic and sensory evaluation of nutritionally enhanced beans and a traditional bean was completed to determine the genotype most likely to be adopted. materials and methods: the study was completed in cesar (colombia), and comprised three phases: 1) evaluation of the acceptance of 35 biofortified bean seeds by 331 bean producers and consumers, 2) agronomic and nutritional evaluation of the eight highest rated beans, and 3) sensorial evaluation by 273 persons in comparison with a regional bean. the four genotypes with the best agronomic and nutritional results were evaluated with acceptability tests, and for the best rated, preference tests and triangular discrimination were also applied. results: the most accepted seeds were two each of the following colors: black, cream, red and pink striped. the four best beans with respect to yield, food safety, and iron and zinc contents included a genotype of each color. compared with a local bean, the four had the same acceptability scores for smell, color and taste (p> 0.05), and different scores for texture and consistency (p <0.05), favoring the biofortified beans, and the black line in particular. with the black bean and a local bean, a recipe was prepared. evaluators discriminated between the two beans and there were differences in the acceptability of certain sensory characteristics in favor of the biofortified line. conclusions: biofortified bean genotypes showed better yield, food safety, and iron and zinc content than the local bean. the four best presented some sensorial differences compared to the control, in favor of the biofortified bean, and specifically the black genotype.

Abstract: Within the enlargement of the collections of the Agrobotanical Garden and Herbarium of the Agrobotanical Institute "Dr. P. Groza" Cluj-Napoca, the regional variability of Phaseolus species (P. vulgaris L. and P. multiflorus Lamk.) cultivated in present's plots in different regions of Transylvania (Romania) have been studied, in accordance with the general principles emphasized by national and international organizations (2, 3). Our Phaseolus collection is represented now by voucher specimens field in the Agrobotanical herbarium of the Institute (CLA 25.794-25.919) and more than 1000 seed samples of ecologically adapted (local) populations or recognized agricultural varieties collected for comparation or cultivation. Some of this samples may be placed at the disposal of the interested research workers by Index Seminum Horti agrobotanici Cluj-Napoca, 1977/1978.

Abstract: It was registered big differences between Phaseolus vulgaris L. cultivars from Romania and from Chile. In the same conditions of field (Agriculture Station from Podu Iloaie, Iasi - Romania) the cultivars from Chile could not reach maturity .The treatment with UV during germination reduced the survival rate.

Abstract: Se desarrolló un modelo experimental in vivo para evaluar la potencialidad de la fitohemaglutinina de 2 variedades de Phaseolus vulgaris de modular el sistema inmunológico. Ratas Wistar macho recibieron 10 y 20 mg/kg de peso de fitohemaglutinina obtenida de las variedades de frijol “Cueto” y “Judía roja Santo Domingo”. Ambos extractos fueron inocuos, incrementaron la masa corporal de los animales y no modificaron el hematócrito ni los conteos celulares de polimorfonucleares neutrófilos, eosinófilos y monocitos. La fitohemaglutinina BETERA obtenida del Phaseolus vulgaris de la variedad “Cueto” fue más efectiva para producir incrementos en el número total de leucocitos y linfocitos circulantes y estimular a los linfocitos B para la producción de anticuerpos An in vivo experimental model was developed to evaluate the potentiality of fitohemaglutinin from 2 varieties of Phaseolus vulgaris to modulate the immunological system. Male Wistar rats received 10 and 20 mg/kg of weight of fitohemaglutinin obtained from the varieties of “Cueto” dry bean and “Santo Domingo” red kidney bean. Both extracts were inocuous, increased the body mass of animals and did not modify either the haematocrit or the cellular counts of polymorphonuclear neutrophiles, eosinophiles and monocytes. BETERA fitohemaglutinin obtained from Phaseolus vulgaris of the “Cueto” variety was more effective to produce increases in the number of circulating leukocytes and lymphocites and to stimulate lymphocytes B for producing antibodies

Abstract: The causes of early embryo abortion in the reciprocal crosses between Phaseolus vulgaris L. and Phaseolus polyanthus Greenm. were studied. Methacrylate resin sections, 2 micron meter thick, of 2 to 6 day-old hybrid seeds were used to examine the stage of embryo development and the state of seed tissues. These observations permitted the determination of the main causes of abortion and the developmental stages at which interspecific embryos should be rescued. Early nutritional barriers in Phaseolus polyanthus (Q) x Phaseolus vulgaris crosses are related to a deficient endosperm development while in reciprocal crosses, endothelium proliferation and, in some extent, hypertrophy of the vascular elements might be the main causes of early embryo abortion. The importance of the abnormalities observed during embryo development depended to a great extent on the compatibility between the genotypes crossed. Results also suggest that the appropriate time for embryo rescue when Phaseolus polyanthus is a female partner is at the early globular stage.
