Una breve pesquisa sobre Crossopetalum gaumeri (Celastraceae). To be, or not to be [endemic], that is the question

RODRIGO STEFANO DUNO DIEGO FRANCISCO ANGULO PEREZ GERMAN CARNEVALI FERNANDEZ CONCHA (2022, [Artículo])

A finales de abril del 2022, un [malvado] colega del herbario CICY informó que habíamos olvidado una especie endémica en nuestra última actualización de endemismo para la Provincia Biótica Península de Yucatán ¡Otra más! Después de algunas angustias y pesquisas sobre la planta, pensamos que era una excelente oportunidad para hablar de una hermosa (o al menos interesante) planta de la región y presentar el caso. Se trata de Crossopetalum gaumeri, de la familia Celastraceae.

Influence of novel coconut oil and beeswax edible coating and MAP on postharvest shelf life and quality attributes of lemon at low temperature

Mohammad Mainuddin Molla Ashfak Ahmed Sabuz Md Abdul Matin (2023, [Artículo])

Weight loss, turning of peel colour from green to yellow and microbial infections are the major postharvest problems of lemon. Lipid-based edible coatings and modified atmospheric packaging (MAP) are effective techniques in maintaining postharvest quality of fruits for long-term storage. With this view, an investigation was conducted for the preservation of green lemon using coconut oil and beeswax edible coating and MAP during storage at low temperature. Physiologically matured lemons were collected and washed with potable water; fruit surface water was removed and then coated with coconut oil-beeswax (90:10) or only coconut oil. After coating, lemons were packaged in MAP or kept in open crates and stored at 12±1 °C and 85±5% relative humidity (RH) for 8 weeks and a week interval, the sampling was conducted. The results revealed that coconut oil-beeswax coating had immense effect on retaining shiny green colour, reducing respiration, weight loss, shrivelling and preserving firmness and ascorbic acid of lemon throughout the storage. On the other hand, MAP mainly helped to retain moisture & firmness and reduce shrivelling. Uncoated lemons kept open lost the highest amount of ascorbic acid and retained only 13.7 mg/100 g that is significantly (p < 0.05) less than the lemons of all other treatments at 8th week of storage period. While lemons coated with coconut oil-beeswax and packaged in MAP was preserved the highest amount (24.2 mg/100 g) of ascorbic acid and there was no significant difference (p < 0.05) with the amount of ascorbic acid content of lemons coated with only coconut oil and packaged in MAP at the last week (8th week) of storage. Hue angle value was 93.4 in uncoated lemons packaged in MAP while it was 113.67 in coconut oil-beeswax coated lemon kept open and 112.64 in lemon coated with coconut oil-beeswax and packaged in MAP at 8th week of storage. Based on all sensory, physical and chemical parameters uncoated lemons kept open was acceptable up to 1 week, coconut oil-beeswax coated lemon kept open was 6 weeks and coconut oil-beeswax coated lemon packaged in MAP was 8 weeks with good quality and shiny green colour.

On-farm assessment of yield and quality traits in durum wheat

Facundo Tabbita Iván Ortíz-Monasterios Francisco Javier Pinera-Chavez Maria Itria Ibba Carlos Guzman (2023, [Artículo])

BACKGROUND: Durum wheat is key source of calories and nutrients for many regions of the world. Demand for it is predicted to increase. Further efforts are therefore needed to develop new cultivars adapted to different future scenarios. Developing a novel cultivar takes, on average, 10 years and advanced lines are tested during the process, in general, under standardized conditions. Although evaluating candidate genotypes for commercial release under different on-farm conditions is a strategy that is strongly recommended, its application for durum wheat and particularly for quality traits has been limited. This study evaluated the grain yield and quality performance of eight different genotypes across five contrasting farmers’ fields over two seasons. Combining different analysis strategies, the most outstanding and stable genotypes were identified. RESULTS: The analyses revealed that some traits were mainly explained by the genotype effect (thousand kernel weight, flour sodium dodecyl sulfate sedimentation volume, and flour yellowness), others by the management practices (yield and grain protein content), and others (test weight) by the year effect. In general, yield showed the highest range of variation across genotypes, management practices, and years and test weight the narrowest range. Flour yellowness was the most stable trait across management conditions, while yield-related traits were the most unstable. We also determined the most representative and discriminative field conditions, which is a beneficial strategy when breeders are constrained in their ability to develop multi-environment experiments. CONCLUSIONS: We concluded that assessing genotypes in different farming systems is a valid and complementary strategy for on-station trials for determining the performance of future commercial cultivars in heterogeneous environments to improve the breeding process and resources.

CÓMO LLEVAR YUCATÁN A CUESTAS : LAS FOTOGRAFÍAS DEL ESTADO DE YUCATÁN EN LA EXPOSICIÓN HISTÓRICO-AMERICANA DE MADRID EN 1892

Marisol Domínguez González (2023, [Tesis de maestría])

“En el marco de las celebraciones del IV Centenario del llamado Descubrimiento de América, España organizó en Madrid la exposición Histórico-Americana de 1892, una muestra internacional que reunió a varios países, la mayoría antiguas colonias española, y con la que buscaba ostentar, entre otras cosas, su influencia en el desarrollo de estos territorios. Hacia la última década del siglo XIX los objetos fotográficos ya figuraban en las exposiciones universales fungiendo como una herramienta visual más para construir la imagen y/o la narrativa que un territorio, país o nación pretendía mostrar. Esta investigación explora la colección fotográfica que México presentó en la Exposición Histórico-Americana y se concentra específicamente en las fotos del estado de Yucatán. Con la intención de entender el papel de los conjuntos de fotografías en los procesos de construcción y exposición de un discurso local y nacional, aquí se indaga el qué y el cómo se mostró a México y a Yucatán a través de estas imágenes. Las fotos de Yucatán son series de diversa proveniencia, manufactura y temática que el gobierno estatal envió a la Junta Colombiana, instancia encargada de diseñar la propuesta expositiva de México. Estos objetos, que funcionaron como carta de presentación del estado de Yucatán en Madrid, se abordan dentro de la amplia colección fotográfica que México expuso. A su vez, para contextualizarla, se reconstruyen las salas de México y se revisa la propuesta expositiva y el proceso de participación del país dentro de la lógica general de la Exposición Histórico-Americana”.
