  • Herbal extracts and alcohol increase vase life of Dianthus caryophyllus L.
           cv ‘Yellow Candy’

    • Abstract: Abstract Some chemicals such as 8-HQS used for prolonging the vase life of cut flowers are harmful to human health. Therefore, it is necessary to identify natural compounds to delay senescence and the deterioration of cut flower tissues. Essential oils with antimicrobial properties can have a significant effect on the vase life of cut flowers. The objective was to compare the effect of essential oils (geranium [Pelargonium graveolens], caraway [Cuminum cyminum] and dill [Anethum graveolens]) against 8-HQS and alcohol on postharvest life, bacterial control and some qualitative characteristics of cut carnation (Dianthus caryophyllus L. cv ‘Yellow Candy’) flowers. Gas Chromatography/Mass Spectrometry (GC/MS) analysis of the essential oils showed that the highest percentage of essences in geranium (13.03 %), caraway (26.05 %) and dill (52.23 %) were geraniol, methyl-3-phenyl-2-propenal and linalool, respectively. Vase life increased to 15.43 and 15.11 days when using 100 mg·L-1 dill and 50 mg·L-1 geranium, respectively. Solution uptake (2.18 mL·g-1 FW) and the activity of catalase (1.78 µg·g-1 FW) were also highest in 100 mg·L-1 dill essential oil solution compared to distilled water (1.07 mL·g-1 FW and 0.90 µg·g-1 FW, respectively). The 2 % alcohol, 100 mg·L-1 dill, 50 mg·L-1 geranium, and 100 mg·L-1 caraway induced the longest vase life, with dill essential oil being the most suitable, effective and safest treatment.Resumen Algunas sustancias químicas, como la 8-HQS, utilizadas para prolongar la vida en florero de flores de corte son perjudiciales para la salud humana. Por ello, es necesario identificar compuestos naturales para retrasar la senescencia y el deterioro de los tejidos de las flores de corte. Los aceites esenciales con propiedades antimicrobianas pueden tener un efecto significativo sobre la vida en florero. El objetivo fue comparar el efecto de aceites esenciales (geranio [Pelargonium graveolens], comino [Cuminum cyminum] y eneldo [Anethum graveolens]) contra 8-HQS y alcohol, sobre la vida poscosecha, el control bacteriano y algunas características cualitativas de las flores de corte de clavel (Dianthus caryophyllus L. cv ‘Yellow Candy’). El análisis por cromatografía de gases/espectrometría de masas (CG/EM) de los aceites mostró que el mayor porcentaje de esencias en geranio (13.03 %), comino (26.05 %) y eneldo (52.23 %) fue el geraniol, el metil-3-fenil-2-propenal y el linalool, respectivamente. La vida en florero aumentó a 15.43 y 15.11 días al utilizar 100 mg·L-1 de eneldo y 50 mg·L-1 de geranio, respectivamente. La absorción de solución (2.18 mL·g-1 PF) y la actividad de la catalasa (1.78 µg·g-1 PF) también fueron las más altas con 100·mg·L-1 de eneldo, en comparación con el agua destilada (1.07 mL·g-1 PF y 0.90 µg·g-1 PF, respectivamente). El alcohol al 2 %, 100 mg·L-1 de eneldo, 50 mg·L-1 de geranio y 100 mg·L-1 de comino indujeron la mayor vida en florero, siendo el aceite esencial de eneldo el tratamiento más adecuado, eficaz y seguro.
  • The use of plant growth retardants in tomato (Solanum
    L.) seedlings

    • Abstract: Abstract An alternative tomato production system consists of establishing three short crop cycles per year and managed with a high population density (9 plants·m-2) and early blunting. For this purpose, it is necessary to extend the seedbed phase until two months. The aim of this study was to evaluate the effect of three growth retardants (Uniconazole, Paclobutrazol and Propiconazole) on the quality of DRD 8537 commercial hybrid tomato seedlings, with one or two applications (at 25 and 50 days after sowing [das]) and two doses per retardant (low and high). Plant height, stem diameter, and number of leaves were evaluated at 31, 49 and 66 das. In addition, the leaf area, fresh weight, and dry matter content of the plants were evaluated at 66 das. The retardants affected height, diameter, fresh weight, and dry matter. The number of applications had no significant effect, and the high dose reduced height and leaf area. The retardants allowed extending seedling time on the seedbed until two months without affecting plant quality. Paclobutrazol was the retardant with the best response in terms of reducing height and leaf area, resulting in more compact seedlings.Resumen Un sistema alternativo de producción de jitomate consiste en establecer tres ciclos cortos de cultivo al año manejados con alta densidad de población (9 plantas·m-2) y despuntes tempranos. Para lograr lo anterior, es necesario alargar la fase de almacigo hasta dos meses. En este estudio, el objetivo fue evaluar el efecto de tres retardadores de crecimiento (Uniconazol, Paclobutrazol y Propiconazol), con una o dos aplicaciones (a los 25 y 50 días después de la siembra [dds]) y dos dosis por retardador (baja y alta), sobre la calidad de plántulas de jitomate del híbrido comercial DRD 8537. A los 31, 49 y 66 dds se evaluó la altura de planta, el diámetro de tallo y el número de hojas. A los 66 dds, además de lo anterior, se evaluó el área foliar, el peso fresco y el contenido de materia seca de la planta. Los retardadores afectaron la altura, el diámetro, el peso fresco y la materia seca. El número de aplicaciones no tuvo efecto significativo, y la dosis alta redujo la altura y el área foliar. Los retardadores permitieron alargar el periodo de la plántula en almacigo a dos meses, sin afectar su calidad. El Paclobutrazol fue el retardador que tuvo mejor respuesta en la reducción de la altura y el área foliar, lo cual se traduce en plántulas más compactas.
  • Rice husk biochar as a substrate for growth of cucumber seedlings

    • Abstract: Abstract Biochar is a carbon-rich material derived from plant residues and obtained by thermochemical techniques in an oxygen-limited environment or in the absence of it. The aim was to evaluate the physical properties of mixtures of rice husk biochar as a substrate component and their effect on the growth of cucumber seedlings. The treatments were: rice husk biochar (BC) and commercial peat moss (T; Sunshine mix 3), as well as mixtures of both in different proportions (20:80, 40:60, 60:40 and 80:20 %, respectively). For physical characterization, particle size, bulk density, total porosity, aeration porosity and water-holding porosity were evaluated. Additionally, nutrient concentration was determined. To evaluate the effect of biochar on cucumber seedling growth, stem length, fresh weight of aerial and root biomass, leaf area, dry weight of aerial and root biomass, and relative chlorophyll content (SPAD readings) were considered. It was found that the addition of up to 40 % BC to the universal growth medium (peat moss) does not alter the physical properties of total porosity, aeration porosity, and water-holding porosity; furthermore, the growth of cucumber seedlings in a 20 % BC mixture is similar in stem length, fresh biomass, dry biomass and leaf area to seedlings grown with 100 % peat moss.Resumen El biocarbón es un material rico en carbono derivado de residuos vegetales y que se obtiene mediante técnicas termoquímicas en un ambiente limitado de oxígeno o en ausencia de éste. El objetivo fue evaluar las propiedades físicas de mezclas de biocarbón de cascarilla de arroz como componente de sustrato y su efecto en el crecimiento de plántulas de pepino. Los tratamientos fueron: biocarbón de cascarilla de arroz (BC) y turba comercial (T; Sunshine mix 3), así como mezclas de ambos en diferentes proporciones (20:80, 40:60, 60:40 y 80:20 %, respectivamente). Para la caracterización física, se evaluó la granulometría, la densidad aparente, la porosidad total, la porosidad de aireación y la porosidad de humedad. Adicionalmente, se determinó la concentración nutrimental. Para evaluar el efecto del biocarbón en el crecimiento de plántulas de pepino se consideró la longitud de tallo, el peso fresco de biomasa aérea y de raíz, el área foliar, el peso seco de biomasa aérea y de raíz, y el contenido relativo de clorofila (lecturas SPAD). Se encontró que la adición de hasta 40 % de BC al medio de crecimiento universal (turba) no altera las propiedades físicas de porosidad total, porosidad de aireación y porosidad de retención de humedad; además, el crecimiento de plántulas de pepino en mezcla de BC al 20 % es similar en longitud de tallo, biomasa fresca, biomasa seca y área foliar a las plántulas cultivadas con 100 % de turba.
  • Study of inbreeding in tomatillo (Physalis ixocarpa Brot.
           ex Horm.)

    • Abstract: Abstract Only intervarietal and interfamilial hybridization can be carried out in tomatillo. Therefore, the objective was to study the effect of inbreeding in families of four varieties of tomatillo obtained through three generations of mating by fraternal and plant-to-plant crosses. The varieties studied were Tecozautla, Diamante, Manzano and Morado, each represented by three maternal half-sib families (Generation 1). In 2018, plant-to-plant and fraternal crosses were made in selected plants within each family, resulting in full-sib (FSF) and maternal half-sib (MHSF) families, respectively (Generation 2). In 2019, the process was repeated in Generation 2 families, and another generation of FSFs and MHSFs (Generation 3) was obtained. Field evaluation was conducted in 2020. A randomized complete block design with four replications was used, and yield per plant was evaluated in two harvests and total yield per plant, as well as fruit weight, volume and bulk density, in each harvest and average of harvests. Inbreeding depression occurred among generations. Fruit yield, size and volume in the first harvest decreased over generations. The Tecozautla and Diamante varieties showed greater inbreeding depression. The type of cross had a different effect depending on the variety. Fruit size was lower in plant-to-plant crosses in Tecozautla, Diamante and Morado; that is, they generated greater inbreeding depression than the fraternal crosses.Resumen En tomate de cáscara sólo se puede hacer hibridación intervarietal e interfamilial. Por ello, el objetivo fue estudiar el efecto de la endogamia en familias de cuatro variedades de tomate de cáscara obtenidas a través de tres generaciones de apareamiento por cruzas fraternales y planta a planta. Las variedades estudiadas fueron Tecozautla, Diamante, Manzano y Morado, cada una representada por tres familias de medios hermanos maternos (Generación 1). En 2018 se realizaron cruzas planta a planta y fraternales en plantas seleccionadas dentro de cada familia, lo que dio origen a familias de hermanos completos (FHC) y medios hermanos maternos (FMHM), respectivamente (Generación 2). En 2019, el proceso se repitió en las familias de la Generación 2, y se obtuvo otra generación de FHC y FMHM (Generación 3). La evaluación en campo se realizó en 2020. Se usó un diseño de bloques completos al azar con cuatro repeticiones, y se evaluó el rendimiento por planta en dos cortes y total, así como el peso, el volumen y la densidad aparente de frutos, en cada corte y promedio de cortes. Se presentó depresión endogámica entre generaciones. El rendimiento, el tamaño y el volumen de fruto en el primer corte disminuyó con el paso de las generaciones. Las variedades Tecozautla y Diamante presentaron mayor depresión endogámica. El tipo de cruza tuvo un efecto diferente en función de la variedad. El tamaño de fruto fue inferior en cruzas planta a planta en Tecozautla, Diamante y Morado; es decir, generaron mayor depresión endogámica que las cruzas fraternales.
  • Lead recovery in artificially contaminated agricultural soil as a
           remediation strategy using sunflower and vermicompost

    • Abstract: Abstract Lead (Pb) contamination is an environmental problem that deteriorates the quality of agricultural soils; therefore, it is a priority to evaluate remediation strategies for its recovery. The aim of this research was to evaluate the effect of sunflower (Helianthus annuus) and vermicompost in the remediation of agricultural soils artificially contaminated with Pb. The treatments studied were: T1 (soil with Pb, vermicompost and sunflower), T2 (soil with Pb and vermicompost), T3 (soil with Pb and sunflower) and T4 (soil with Pb). The initial Pb value in the soil was 16.05 ppm, and 105 ppm Pb were added by dissolving Pb(NO3)2, reaching a concentration of 121.05 ppm as the initial level, higher than the national environmental quality standard (EQS) for agricultural soils (70 ppm Pb). All treatments reduced the Pb concentration in the soil below the EQS. T2 stood out by achieving a Pb recovery of 81.21 %. The Pb bioconcentration factor (BF) in the aerial part and roots of sunflower plants (T1 and T3) registered values of less than one, acting as an exclusive plant species. According to the Pb translocation factor (TF), sunflower in the presence of vermicompost (T1) behaved as a Pb phytostabilizing plant (TF < 1), and in the absence of vermicompost (T3) it proved to be a Pb phytoextractor (TF > 1).Resumen La contaminación con plomo (Pb) es un problema ambiental que deteriora la calidad de suelos agrícolas; por ello, es prioritario evaluar estrategias de remediación para su recuperación. El objetivo de esta investigación fue evaluar el efecto del girasol (Helianthus annuus) y el vermicompost en la remediación de suelos agrícolas contaminados artificialmente con Pb. Los tratamientos estudiados fueron: T1 (suelo con Pb, vermicompost y girasol), T2 (suelo con Pb y vermicompost), T3 (suelo con Pb y girasol) y T4 (suelo con Pb). El valor inicial de Pb en el suelo era de 16.05 ppm, y se agregaron 105 ppm de Pb mediante una disolución de Pb(NO3)2, alcanzando una concentración de 121.05 ppm como nivel inicial, superior al estándar de calidad ambiental (ECA) nacional para suelos agrícolas (70 ppm de Pb). Todos los tratamientos redujeron la concentración de Pb en el suelo por debajo del ECA. El T2 destacó al lograr una recuperación de Pb de 81.21 %. El factor de bioconcentración de Pb (FB) en la parte aérea y raíces de las plantas de girasol (T1 y T3) registró valores menores a uno, desempeñándose como una especie vegetal exclusora. Según el factor de traslocación de Pb (FT), el girasol en presencia de vermicompost (T1) se comportó como una planta fitoestabilizadora de Pb (FT < 1), y en ausencia de vermicompost (T3) demostró ser fitoextractora de Pb (FT > 1).
