The Effect of Stage of Maturity on the Quality of Lima Beans for ProcessingRahman, Abdul Razzaq Abdul 01 May 1954 (has links)
Lima bean.is one of the important vegetable crops in most of the countries where it is grown, including the United States of America. This crop is harvested for its green beans, which can also be processed, or allowed to mature as "dry beans."
The practice of growing lima beans !or processing has indicated that quality and yield are influenced by many factors, among which the stage of maturity at time of harvest is possibly the most important.
Lima beans continue to increase in size until fully matured, but most processors agree th.at the green beans attain maximum quality prior to that stage, after which the yield increases while the quality decreases. In actual practice, harvesting should occur at the time the greatest yield of acceptable quality could be obtained. Maturity is thus an extremely important factor to processors interested in satisfying the consumer's demand !or high quality. The canning trade (16) still has no further measurements !or grading the quality of raw lima beans than the visual test, which depends upon the flavor, texture, and freedom from defects. It would seem, therefore, th.at more exact information is needed on the relationship of maturity to edible quality in lima beans.
In studies with other vegetables it has been shown that certain chemical and physiological changes are involved as the crop matures. Pollard, Wilcox, and Peterson (5) found with peas that the starch content increased as the peas advanced in maturity, while ascorbic acid content decreased with maturity. Henry, Wilcox, Pollard, and Lindquist (15) found that in sweet corn the total and reducing sugars decreased as sweet corn advanced in maturity while the total solids and alcohol insoluble solids increased. These changes often influence quality adversely.
To determine more fully the factors affecting the relationship of stage of maturity and quality in lima beans, this experiment was conducted in 1953 at the Farmington Field Station of the Utah Agricultural Experiment Station.

A Vibratory Conveying System for Automatic Sorting of Lima Beans through Image ProcessingInjante, Hugo, Gutierrez, Esteban, Vinces, Leonardo 01 September 2020 (has links)
El texto completo de este trabajo no está disponible en el Repositorio Académico UPC por restricciones de la casa editorial donde ha sido publicado. / In order to comply with lima beans peruvian export standards, this study develops an automatic sorter machine. This system uses vibratory conveying to linearly move the grains and to allow their faces to rotate. In addition, image processing algorithms were used for the detection and rejection of defective lima beans. After performing 2200 sorting tests, an industrial performance with an efficiency of 96.81% in acceptance and 95.26% in product rejection was obtained

Previous issue date: 2005-02-22 / Coordenação de Aperfeiçoamento de Pessoal de Nível Superior - CAPES / Twenty-two lima-beans accessions, which compound the Germoplasm Collection of the Agronomy Department of Federal Rural University of Pernambuco (UFRPE), coming from the States of Ceará, Paraíba and Pernambuco, Brazil, were characterized by their morphological and molecular characteristics (RAPD – Random Amplified Polimorphiysm of DNA). In morphological analysis twenty-four characteristics and in the molecular one were used, seventy-six locis RAPD (polymorphic and morphologic). At the first phase was carried out molecular analyses of twenty-two accessions to assess the genetic variability among them, and then, fourteen of these were morphologically and moleculary characterized. The analysis of sample showed the formation of two main groups and four subgroups. We noticed high genetic variability among the twenty-two accessions. The genetically closer genotypes were FA-01 and FA-02, coming from Ceará, with 85.4% similarity, and the less similar were FA-07 and FA-20, coming from Ceará and Pernambuco, respectively, with 35.9% similarity. Related to the morphological characterization of the fourteen accessions, noticed the genotype FA-13 stood out from the others by presenting higher values of seed weight, number of seeds per pod, length and width of pod, while the FA-16 presented lower values of weight ofone hundred seeds, seeds very small, lower number of pod per plant, lower length of pod and lower production. / Os acessos de feijão-fava que compõe a Coleção de Germoplasma do Departamento de Agronomia da Universidade Federal Rural de Pernambuco (UFRPE) oriundos dos Estados do Ceará, Paraíba e Pernambuco, foram caracterizados quanto às características morfológicas e moleculares (RAPDRandom Amplified Polimorphiysm of DNA). Na análise foram utilizados vinte e oito características morfológicas e setenta e seis locos RAPD (polimórficos e monomórficos). Na primeira etapa foi realizada a análise molecular de vinte e dois acessos para avaliar a variabilidade genética entre eles. Quatorze destes acessos foram caracterizados morfológica e molecularmente. A análise de agrupamento mostrou a formação de dois grupos principais e quatro subgrupos, constatou-se elevada variabilidade genética entre os vinte e dois acessos. Os genótipos mais próximos geneticamente foram FA-01 e FA-02, provenientes do Ceará, com grau de similaridade de 85,4% e os mais distantes foram FA-07 e FA-20, provenientes do Ceará e Pernambuco, respectivamente, com grau de similaridade de 35,9%.Quanto à caracterização morfológica dos quatorze acessos, observou-se que o genótipo FA-13 se destacou dos demais por apresentar maiores valores no peso das sementes, no número de sementes por vagem, no comprimento e largura da vagem, enquanto o genótipo FA-16 apresentou menores valores de peso de cem sementes, sementes muito pequenas, menor número de vagem por planta, menor comprimento de vagem e menor produção de semente por planta.
