| A study was undertaken to classify the banana fruits based on their ripening/maturity by using zNose flavour detection technique. The quality parameters of banana fruits viz., respiratory quotient (RQ), total soluble solids (TSS), moisture content and firmness at each ripening/maturity stage were determined and the results were correlated with zNose flavour data. The principal component analysis (PCA) was used to identify the ripening/maturity stages of banana fruits and also to test the variability of the observed data. By using multiple linear regression (MLR), models were established to predict the fruit quality parameters. The coefficient of determination (r2) corresponding to the predicted respiratory quotient, total soluble solids, moisture content... |

| The performance evaluation of an existing kenaf decorticator was carried out in this study. A field was planted with kenaf at the Teaching and Research Farm (T&RF) of the Obafemi Awolowo University, Ile Ife. The field was maintained and monitored until the kenaf was 10 weeks old when the evaluation of the machine commenced. The kenaf decorticator was evaluated using different operation parameters, which include plant age (10, 11 and 12 weeks after planting), kenaf stem size (small, medium and large) and decorticator speeds (520, 600 and 680 rpm) giving rise to a 3 by 3 factorial experiment. The result showed that the highest mean of throughput value... |

| ABSTRACT The sardine Sardinella aurita, fished since 1927, is Venezuela's most significant fishery resource. The national catch reached a record high of 200,000 tons in 2004 but diminished nationally by 50% in 2005 and by 90% on Margarita Island, marking the beginning of a crisis in sardine fishing. Based on indicators of overexploitation, the fishing authority increased the minimum size required for capture and prohibited fishing for three months in 2013. The validity of these measures is studied here. A reduction in size may indicate intensive exploitation, and thus, the records of 28,217 sardines measured between 2002 and 2016 in the southeast region of Margarita Island were examined. Prior to the crisis, in 2003 and 2004, the average size was 195.48... |

| The physic nut (Jatropha curcas L.) has great potential for use in biodiesel production due to the high oil content of its seeds. Production of high quality seeds depends upon the appropriate time of harvest. A field experiment was carried out to monitor the maturation process of physic nut seeds and to establish the ideal harvest time of the seeds based on external fruit color. Fruits were collected at different maturation stages based on the external color: green, yellow-green, yellow, yellow-brown and brown. Seeds were extracted manually and, after natural drying, were submitted to the following tests and determinations: moisture content and dry matter, germination, first count seedling emergence, seedling growth, accelerated aging, electrical... |

| The objective determination of the optimal harvest date for plums intended either for industrial processing or for consumption as fresh fruit is a fundamental concern of the fruit industry. A portable visible/near infrared (Vis/NIR) spectroscopic device was used to sort D'Agen plums harvested around the traditional commercial harvest date. The chlorophyll absorbance index was found to be capable of segregating plums into classes of maturity according to various concentrations of soluble solids and fruit compression strenght values. Fruits with a chlorophyll absorbance index value of less than 1.59 showed no differences in flesh firmness. Plums harvested with chlorophyll absorbance index values of 1.20-1.29 had a fruit compression strenght of 1.25 N and a... |

| The physiological state of a fruit is closely related to ripening and climatic conditions during the growing period when the fruit undergo changes in color, texture, and flavor. The ripening of the fruit can involve a complex series of biochemical reactions with alteration in enzymes activities, phenols, tannins, and ascorbic acid. The activity of enzymes (carboximethylcellulase, polygalacturonase, and pectinlyase), the total concentration of phenolic compounds, condensed tannins, and vitamin C in five stages of maturation were studied. Significant changes were observed between the maturity stages. The phenolic compounds were higher at green stage (705.01 ± 7.41); tannins were higher at green/purple stage (699.45 ± 0.22). The results showed that the... |

| Con la finalidad de estudiar los mejoradores orgánicos de lupinus, se estableció una fase en laboratorio, en el cual se incubó durante 58 días en condiciones controladas de humedad y temperatura, se realizaron mezclas de suelo tipo franco arenoso en combinación con mejoradores orgánicos de Lupinus montanus Kunth en verde (Av), compost maduro (Cm) y vermicompost maduro (Vc). Los resultados obtenidos indicaron que Av presentó un mayor desprendimiento de CO2, mientras que el Cm y el Vc presentaron menor acción de la biomasa microbiana, esto se puede atribuir a que los mejoradores orgánicos presentaban distintas etapas de descomposición. En la fase campo, se estableció el experimento en San Pablo Ixayoc; en un primer tratamiento se incorporó 25.22 kg de... |

| Bulked segregant analysis was used to identify simple sequence repeat (SSR) markers associated with pod and kernel traits in cultivated peanut, to permit rapid selection of superior quality genotypes in the breeding program. SSR markers linked to pod and kernel traits were identified in two DNA pools (high and low), which were established using selected F2:6 recombinant individuals resulting from a cultivated cross between a runner (Tamrun OL01) and a Spanish (BSS 56) peanut. To identify quantitative trait loci (QTLs) for pod and kernel-related traits, parents were screened initially with 112 SSR primer pairs. The survey revealed 8.9% polymorphism between parents. Of ten SSR primer pairs distinguishing the parents, five (PM375, PM36, PM45, pPGPseq8D9, and... |

| The aim of this study was to determine quality changes in petioles of self-blanching celery (Apium graveolens), cv. Golden Boy, harvested at 80, 87, 94, 101, 108, 115, 122 and 129 days after-transplanting (DAT). Total weight (TW), total length (TL), number of leaves per plant (LN) and by plant zone (external, LNZ E; middle, LNZ M; internal, LNZ I), and petiole length (PL) were evaluated at each harvest time. Petioles quality of each zone in the plant were analyzed in terms of: color (hue angle), texture (cutting force), total soluble solids content (TSS) and titratable acidity (TA). The petioles also were sensorially evaluated by descriptive analysis considering visual characteristics (flexibility, hollowness), flavor (typical flavor and odor) and texture... |

| This study summarizes the results of the processing and analysis of data from illegal fisheries, apprehended by the eco-guards of the Marine Natural Reserve of Reunion from 2015 to 2017 (including the first dataset from 2018). These information are valued in terms of fisheries and bioecological knowledge for reef fish species. Thus, both diversity and abundance indices, size structures, growth parameters, stock characterization, can be apprehended from the biological parameters collected on all the species caught because they often do not exist : the sizes, weights, sexes, maturities, scales, otoliths, stomach contents as well as genetic and isotopic samples. These indices would contribute to a better diagnosis of the status and the sensitivity of stocks... |

| Estimating the productivity of an exploited marine species is not an easy or a trivial task. In the case of Atlantic bluefin tuna, the productivity can hardly be estimated from the natural mortality rates or the stock recruitment relationships because the former have never been estimated for this species from scientific data, but only “guesstimated”, while the latter remain highly uncertain for both the eastern stock (BFTE) and the western stock (BFTW). To get a better idea of bluefin tuna productivity, we thus applied the approach by Jennings et al. (1998) who proposed a surrogate of r, r’, named the potential rate of population increase. We compared this parameter and age-at-maturity (and to some extent the individual growth curves) of 25 species... |
