  1. A diversidade tipológica na composição de palavras neoclássicas agro-X

    Silva, Neide Higino da
    This paper investigates the structural and semantic relations of constructions which present the “agro-” formative called neoclassical compounds such as agronomia, agromoda and agrocombustível. The objective is to identify characteristics that can establish links between constructions which, at first, show appear as disparate, depending on the various meanings that the same radical can assume (agro- can mean campo in agrologia, produtos agrícolas in agroexportação and ciências agrárias in agroveterinária). However, these compounds exhibit a degree of relational similarity that influence the categorization of these constructions. The examined data have been selected by Higino da Silva (2016). The theoretical framework that...

    Palacios Díaz, Miriela; Aguilar Hernández, Vadim
    The following article studies the professionalization of the English teaching- learning process in the students of the Agronomy specialty in the Polytechnic Center Pedro Concepción Tamargo in Consolacion del Sur. In the English teaching-learning process mentioned before we have been found limitations among the students to communicate and to process orally and written information in the English language as well as the use of English language for the development of the skills that compose the group of procedures, tecnics and strategies they should use to solve professional problems related with their professional life. That is why the author proposes as...

  11. Producción de melón en invernadero: comparación agronómica entre tipos de melón

    Monge Pérez, José Eladio; Loría Coto, Michelle
    En esta investigación, se evaluaron siete tipos de melón (Cucumis melo L.): el amarillo, el cantaloupe, el charentais, el galia, el harper, el honey dew y el japonés, producidos bajo invernadero en condiciones hidropónicas en Alajuela, Costa Rica, para determinar su rendimiento y calidad, en los niveles cualitativo (una variable) y cuantitativo (seis variables). Todos los genotipos de los melones tipo amarillo, honey dew y japonés presentaron plantas andromonoicas, mientras que, en los demás tipos, se presentaron genotipos monoicos y andromonoicos. Los datos muestran una amplia variabilidad entre los tipos de melón en cuanto a número de frutos por planta...

    The 'Persian' lime is the most exported citrus in Mexico, the principal producing area is concentrated in Martinez de la Torre, Veracruz. The rootstock most used in the region is the 'Agrio'orange, but is susceptible to tristeza citrus virus. New options for fruit production are longer necessary. Objective of this work was to determine the fruit quality of 'Persian' lime on different rootstocks (Citrumelo 'Swingle', 'Macrophylla' lemon, 'Agrio' orange, 'C35' and 'Troyer' citrange, 'Volkamer' lemon, 'Palestine Sweet lime' and 'Flying Dragon' orange). From each treatment 10 fruits were harvested. Variables evaluated were fruit mass, polar diameter, equatorial diameter, polar/equatorial diameter ratio, skin thickness, fruit firmness,...

    Zephyranthes plants (Amaryllidaceae) are mostly wild and there is no information to enable its commercial production. Vegetative and sexual propagation of mayito plants (Zephyranthes fosteri Traub and Z. lindleyana Herb.) was evaluated using different induction methods for formation of bulblets from mother bulbs. Bulbs 2.1 to 2.3 cm in diameter were used, those were cut in six ways to induce shoots: 1) full bulb; 2) cross-sectional cut; 3) longitudinal cut; 4) cut in the shape of an “A” cut; 5) cross-sectional and longitudinal cut, and 6) cross-sectional and longitudinal cut splitting the scales of the basal sections into two parts.

    Albino-Garduño, Rocio; Turrent Fernández, Antonio; Cortés Flores, José Isabel; Santiago-Mejía, Horacio; Mendoza Castillo, Mª. del Carmen; Jacinto Hernández, Carmen
    Previous studies have shown that yield of corn (Zea mays L.) was higher in strip intercropping with bush beans (Phaseolus vulgaris L.) than in monoculture, under similar agronomic management. However, its quality has not been reported in the hybrid studied. Were studied the effects of: 1) planting arrangement of maize ‘H-155’ and black bush beans ‘8025’ in strip intercropping system, 2) the rate of nitrogen (N), phosphorus (P), potassium (K) and 3) density (D) on the corn yield (Ym) and yield components, as well as, its quality in terms of protein content (ProtG), P and K. A field experiment (split plot design experimental) was set...

  17. Termoterapia y preacondicionamiento, en la germinacion de cuatro colectas de chile silvestre (Capsicum annum var. Aviculare) de Tamaulipas, México

    Mireles Rodriguez, Epifanio; Moctezuma Balderas, Norma Leticia; Castro Nava, Sergio; Lucio Castillo, Hermilo; Pérez Jasso, Clarisa; Salazar Hernández, Rolando
    The objective was to evaluate the percentage of germination and agronomic suitability of four wild chili (Capsicum annuum L. var. aviculare [Solanaceae]) collections from Ocampo, El Chamal, Jaumave and Tula, Tamaulipas. A preliminary characterization of the seeds considering the seed weight, number of fruits per single seed and seed weight was carried out. The results indicate that biotypes Chamal and Ocampo obtained the largest number of seeds per fruit in the fruit characterization. On the other hand, the collection from Ocampo germinated at 17 days after planting, after six minutes of exposure with water to 50 °C and 5,000 ppm AG3. The seed treatment with...

  18. Estenospermocarpia en mango 'Ataulfo': Nayarit y Chiapas

    Balois-Morales, Rosendo; Hernandez Guerrero, Sara Elena; Bello Lara, Juan Esteban
    The mango (Mangifera indica L.) is native of India and is grown in around 90 countries. México produces 1,603,809.53 t per year where 'Ataulfo', 'Haden', 'Keiit', 'Kent', 'Manila', and 'Tommy Atkins' besides mango criollo are the major production. The 'Ataulfo' mango is native of Tapachula, Chiapas, Mexico. It is well-known by its wide acceptance in the international and national market due to its excellent organoleptic characteristics. In recent years it has been shown the production of small fruit which have no commercial value severely affecting the finances of regional producers. This phenomenon or condition is denominated as fruit stenospermocarpic which describes fruits with seed partially...
