iaphorina citri is considered the most dangerous citrus pest because it transmits Candidatus Liberibacter asiaticus, the causal agent of Huanglongbing (HLB). Like other hemiptera insects, D. citri has developed mutualistic interactions with prokaryotic organisms known as endosymbionts. This symbiosis can be obligatory, when the interaction occurs with a primary endosymbiont, or facultative, when it is a secondary endosymbiont. Symbiosis is essential for various physiological functions, but some endosymbionts can adversely affect the psyllid's abilities. D. citri is associated with a great diversity of endosymbionts, with Candidatus Carsonella ruddii, Candidatus Profftella armatura, Candidatus Wolbachia spp. and Candidatus Liberibacter spp standing out. The aim o symbiotic relationship, prokaryotes, Candidatus Wolbachia, transmission of Candidatus Liberibacter asiaticus.

Mexico is the world's leading producer of ‘Hass’ avocado and the Antillean race avocado is grown in the south of the country. Avocado plant flowers produce a great variety of volatile compounds, which act as chemical signals to attract herbivores and pollinating insects, in addition to providing information for taxonomic purposes. The research aim was to identify and compare the floral volatiles between the ‘Hass’ and Antillean race avocado. Floral volatiles were captured by solid-phase microextraction, and identification was made by gas chromatography coupled to mass spectrometry (GC-MS). Thirty-five compounds were identified as constituents of the flower aromas; most were monoterpenes and sesquiterpenes. α-Pinene, sabinene, β-pinene, (E)-linalool oxide, benzyl nitrile, lavandulol, methyl salicylate, α-copaene, β-gurjunene and γ-muurolene were only found in ‘Hass’ avocado flowers. The differences can help classify the two types of avocados analyzed into different races. Eventually, this information could be used to find out if these volatile compounds influence the interactions of avocado with its pollinating insects and herbivores.

Avocado is the third most produced crop in the State of Mexico, with 11,296 ha, where the predominant variety is ‘Hass.’ Due to a lack of knowledge about its development in different environments, its agronomic management is highly heterogeneous, since it is based on experiences in other states. The objective of this study was to analyze, describe and quantify the phenological development of ‘Hass’ avocado in three environments in the State of Mexico. The vegetative, flowering, root and fruit development of ‘Hass’ avocado was recorded during the 2011-2012 cycle. Two periods were distinguished for vegetative growth (December-April and October-November), flowering (December-February and August-October), harvest (November-February and August-October) and root growth (April-July and October-December). The vegetative growth (0.40 and 0.06 cm increase in shoot length and diameter, respectively) and root growth (36 and 24 g fresh weight and dry matter, respectively) were lower than fruit growth (70.1 mm increase in diameter) in Coatepec Harinas (temperate with andosol soil and isotherms from 14-18 °C). In contrast, the same growth measurements were higher in the localities with cambisol-luvisol soil and isotherms from 16-20 °C: Ixtapan del Oro (temperate/semi-warm, with 0.69 and 0.12 cm in shoot, and 56 and 48.8 g in root) and Temascaltepec (semi-warm, with 0.78 and 0.23 cm in shoot, and 69.3 and 31.3 g in root), but lower increases in fruit (59.4 and 56.6 mm, respectively). The phenological differences observed among environments will be useful for the technical management of the crop.

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.

By managing tomato at a high population density, blunting to the third cluster and transplanting 40 days after sowing (das), the transplant to end-of-harvest cycle lasts four months, achieving three cycles per year and a potential yield of 500 t∙ha-1-2 for 25 mL, and 300, 200, 150 and 75 seedlings∙m-2 for 250 mL) were evaluated.A split-plot randomized complete block design with four replicates was used. Morphological variables, number of flowers and yield were recorded. Analysis of variance and comparison of means (Tukey, P ≤ 0.05) were performed. Seedlings with morphological characteristics suitable for transplanting at 60 das were those grown in 250 mL cavities at densities of 75 and 150 seedlings∙m-2. Cavity volume and seedling density did not influence the number of flowers or fruits per plant.

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).

El fruto de la guanabana es muy apreciado por sus caracteristicas organolepticas, medicinales y por su diversidad en la industrializacion; sin embargo, no existen variedades generadas en Mexico, a pesar de que se cree que hay gran diversidad de esta especie en el pais. El objetivo de este trabajo fue evaluar la variabilidad entre frutos de guanabana cultivados en cuatro municipios del Soconusco, Chiapas, a partir de sus caracteristicas fisicas y quimicas, y proponer algunos materiales para el consumo en fresco o la industria. Se seleccionaron 28 arboles de huertas comerciales provenientes de semilla con aproximadamente 10 anos de edad. De cada arbol se colectaron seis frutos en madurez fisiologica, posteriormente se maduraron y se evaluaron algunas caracteristicas de calidad, metabolitos funcionales y actividad antioxidante. La poblacion mostro alta variabilidad (entre 42 y 135 %) en el peso de fruto, pulpa, semilla y raquis, asi como en la cromaticidad en pulpa y en cascara, solidos solubles totales, azucares totales y actividad antioxidante. Se determino la formacion de cuatro grupos, donde el 1 y 2 (arboles de Tapachula y Huehuetan) tuvieron los frutos con las mejores caracteristicas de productividad: mayor peso y dimensiones de fruto, mientras que los frutos de los grupos 3 y 4 (arboles de Mazatan y Cacahoatan) se caracterizaron por mejores caracteristicas de sabor, aporte de metabolitos funcionales y mayor actividad antioxidante.

Myrciaria dubia (Kunth) McVaugh is a fruit tree native to the Amazon with great potential due to its nutraceutical properties; thus, ex situ adaptation technologies should be developed. The objective of this study was to determine the evapotranspiration (ETc) and crop coefficient (Kc) of Myrciaria dubia for domestication and conservation on uplands. Two Myrciaria dubia plants of 2, 4, and 6 years old with similar morphological characteristics of height, number of branches (basal and terminal), and diameter (stem and canopy) were transplanted into drainage lysimeters. Residue of organic mulching composed of a native grass (Trachypogon plumosus) was applied once to one plant of each age category. The mean ETc values for 2-, 4-, and 6-year-old plants in the presence and absence of mulch were 2- and 2.7-mm∙day-1, 3.2- and 3.9-mm∙day-1, and 6.1- and 7.2-mm∙day-1, respectively. The mean Kc values in the EI, EII, and EIII phenological stages with and without mulch were 0.4 and 0.6, 0.6 and 0.8, and 1.1 and 1.3, respectively. The ETc and Kc values for Myrciaria dubia plants with organic mulching can be used in irrigation planning for cultivation, domestication, conservation, and efficient use of water resources in tropical savannas of Roraima, Brazil.

T he main collection of allelic variants for breeding tomato ( Solanum Lycopersicum L.) is represented by its wild relatives, which evolved independently. It is important to study different sources of variation that are useful in breeding; therefore, the aim of this study was to evaluate S. habrochaites Knapp & Spooner as a source of different alleles by estimating the average degree of dominance, heterosis with respect to the mid-parent,

One of the advantages of controlled agriculture is the notable increase in crop yields. However, at high-tech levels, water use productivity has increased, while energy use productivity has decreased. Therefore, the objective of this study was to estimate water, energy and labor use productivity in tomato cultivation, for a low-tech greenhouse. The inputs used in the production process were recorded from April 24 (date of transplant) to October 16, 2016 (date of last harvest). The yields obtained were 19.07 kg∙m-2. Water use productivity was 27.86 kg∙m-3 (35.89 L∙kg-1), which is within the range reported for unheated plastic greenhouses (30-40 L∙kg-1). Energy productivity was 0.331 kg∙MJ-1, and the energy consumed per unit area was 57.61 MJ∙m-2, with Calcium nitrate being the input with the highest energy demand (49.49 %). During the production cycle, 738 working hours were used, 78 % of which were dedicated to cleaning and maintenance, with labor productivity of 3.02 kg∙h-1.
