“…Por ello se requiere de un cáliz grande en las amplias estructuras florales que se originan en los frutos del tomate tipo costilla. Diversos estudios demuestran la importancia de la síntesis de fotoasimilados en los órganos fotosintéticos (Martínez et al, 2001;Yin et al 2010), sobre todo los más inmediatos a los frutos como los sépalos (Fridman et al, 2000), como ocurre en otras especies (Marcelis et al, 2004). Urrieta-Velázquez et al (2012) documentaron diferencias en el número de sépalos en tres selecciones de tomate tipo costilla debidas a un efecto interactivo entre la selección y nutrición del cultivo.…”

En la producción de tomate (Solanum licopersicum L.) existen alternativas de manejo ecológico y económico para incrementar el rendimiento, sabor, vida de anaquel y propiedades nutraceúticas que dan valor agregado a la calidad de fruto. El objetivo de la presente investigación fue determinar el efecto del aclareo de racimos y aspersiones foliares de Ca y miel de abeja a 2 % sobre la calidad de frutos de tomate tipo costilla selección Starmex 2. La investigación se realizó en un invernadero, bajo un diseño de bloques completos al azar con arreglo factorial 23 de los tratamientos: dos dosis de calcio (0 y 350 mg L-1), dos niveles de miel de abeja (0 y 2 % p/p) y dos niveles de aclareo de frutos (con y sin), con cuatro repeticiones. Los frutos se cosecharon maduros y en ellos se registró el peso fresco, el diámetro ecuatorial, el número de costillas y sépalos, la acidez titulable, los sólidos solubles totales (°Brix), la concentración de Ca, y las de licopeno y de vitamina C. El número de costillas aumentó (P ≤ 0.05) por el efecto interactivo del aclareo y las aspersiones de calcio. Asimismo el peso del fruto se incrementó por el efecto separado del aclareo y las aspersiones de miel. El diámetro ecuatorial y el número de sépalos del fruto aumentaron (P ≤ 0.05) con el aclareo y las aspersiones foliares de calcio. En las variables de calidad, solamente hubo efecto en los sólidos solubles (°Brix), acidez titulable y vitamina C; que aumentaron por la interacción de Ca y miel de abeja.

“…The exogenous application of plant growth regulators depends on several factors such as the plant genotype, growing season, type of regulator, and applied concentration (Tantasawat et al, 2015). Some have been widely used on vegetables, to improve fruit setting and increase production, such as indoleacetic acid (Montaño-Mata and Méndez-Natera, 2009), gibberellic acid (Pichardo-González et al, 2018), naphthaleneacetic acid (Soriano-Melgar et al, 2020;Sedighehsadat et al, 2021), -naphthoxyacetic acid (Martínez et al, 2016) and forchlorfenuron (CPPU) (Rueda-Luna et al, 2018). In this sense, naphthaleneacetic acid has been widely used in melons (Barzegar et al, 2015;Menchaca-Ceja et al, 2018), however, its effect on zucchini is scarcely known.…”

The cultivation of zucchini (Cucurbita pepo L.) under protected conditions has limitations, such as low fruit set due to poor pollination, which affect the commercial yield and profitability of the crop. The investigation was carried out to know the influence of earthworm humus (HL) and naphthaleneacetic acid (ANA) on the growth and yield of two zucchini cultivars in shade houses. A randomized block experimental design with eight treatments and 10 repetitions was used. The treatments influenced plant height, leaf area index, stem dry weight, leaf dry weight, plant dry weight and fruit set; however, there were no differences because of the treatments in stem diameter, leaf greenness and number of leaves. With the HMX58 cultivar, the highest plant height was obtained: while because of the Prestige cultivar, the highest index of leaf area, dry weight of leaves and dry weight of the whole plant. The highest yield was obtained with the HMX58+LC treatment, while fruit set and number of fruits increased because of earthworm humus. The diameter and weight of the fruit increased because of ANA in both cultivars, and the length of the fruit in the Prestige cultivar.

The experiment was conducted from May to August 2018 at the Technological University of the Southwest of Guanajuato (UTSOE) in a randomized complete block design with three repetitions, in greenhouse 1 of 700 m2 of the Sustainable and Protected Agriculture Career; with the purpose of evaluating the effect of pruning at one and two stems per plant, on yield, fruit weight and plant variables in seven varieties of saladette tomato produced under greenhouse and in hydroponics. The varieties evaluated were: Natalie, USATX 12227, USATX 9934, Juan Pablo, USATX 24019, USATX 16117, USATX 15538, all established at a density of 31,250 plants or stems per hectare. Pruning at two stems per plant produced the highest yield in the USATX 16117, USATX 9934 and Natalie varieties, producing more than 2.3 kg per plant after six weeks of harvest. For the fruit weight, the USATX 9934 variety with two stems, was the one that produced fruits of greater caliber, being one of the three varieties with the highest yield. For the plant height, the USATX 24019 variety with one stem was the one with the highest height three months after the transplant.
