Abstract Sultepec, State of Mexico, located on the central part of Mexico, belongs to the Physiographic province “Sierra Madre del Sur” and to the Subprovince “Depresión del Balsas”. Although it is known for its floristic richness, it lacks an inventory of vascular plants, including the fruit species. The aim of this work was to elaborate a database including family, scientific name, local name, biological form, origin, use, management, production and service of the fruit species. Plants were collected continuously from June 2010 to June 2011. Subsequently, they were determined in the herbarium “Eizi Matuda” (CODAGEM) from the Facultad de Ciencias Agrícolas… More >

Abstract This study contributes to the knowledge of the biodiversity of the flora of the State of Mexico through an analysis of the distribution and abundance of Asclepias curassavica L., which is planted with ornamental and medicinal potential. The study was carried out in the municipalities of Temascaltepec, Malinalco and Valle de Bravo. The spatial statistical method was used to determine the distribution of A. curassavica based on the method SADIE (spatial analysis by remote indexes). Sampling transects of 200 m, marked every 10 m, were used in the three municipalities, during three times of the year, spring, summer and winter.… More >

Abstract The Toluca´s México valley is considered a high valley because it is situated at 2560 m.a.s.l. In this region, maize is the most important crop; free pollination [Yellow, red, blue and flour maize (Cacahuacintle)] and hybrid materials are grown. Corn yield is negatively affected by an inadequate P fertilization. The aim of this study was to determine the agronomic effectiveness of phosphorus in terms of biomass and yield on three cultivars of maize as a function of six levels of phosphorus fertilization in the Toluca´s valley, Mexico. The materials Amarillo Almoloya, Cacahuacintle and Cóndor were sown under a completely randomized… More >

Abstract The aim of this study was to evaluate grain yield (RG) stability of some commercial wheat varieties, and to assess the stability of other parameters which are not typically measured for grain release purposes: performance of straw (RP), weight per hectoliter (PH), white belly (PB), harvest index (IC), grain protein (PG) and gluten strength (W). The evaluation was performed with the wheat varieties Cachanilla F-2000 (C), Yécora F-70 (Y) and Triguenio F-00 (TR), in El Valle de Mexicali, Baja California under four test environments, with the application of the Eberhart and Russell model. The study was developed during the 2010-2012… More >

Abstract We conducted a comparative study from 2008 to 2011 to study the adaptability and stability of grain yield of upland rice in two regions of Campeche, Mexico. The individual and combined statistical analysis, showed highly significant differences in grain yield of different genotypes in both regions. The experimental error variance was uniform, both effects of repetition/location and variety/location were highly significant. The results of analysis for grain yield stability parameters showed highly significant effects for 12 treatments, and significant for one. Eighteen genotypes showed a significant variation in the effects of deviation from the regression parameters of stability. The highest… More >

Abstract The Instituto Nacional de Investigaciones Forestales, Agrícolas y Pecuarias (INIFAP), in Zacatepec Morelos, started a genetic improvement program of wild and semi-cultivated poinsettia plants ("nochebuena de sol"). It is important to generate a phytosanitary database that allows the release of new varieties and hybrids that provide tolerance to the major pathogens reported in cultivated poinsettia plants. The phytosanitary status of the “nochebuena de sol” plants is not available in Mexico, so the objective of this research was to generate preliminary data about viruses associated to these materials. Based on DAS-ELISA and RT-PCR results, we reported the presence of the Tobacco… More >

Abstract Nanche (Byrsonima crassifolia (L.) H.B.K.) grows in the southeastern region of the Mexican republic under both wild and semi-cultivated forms. Despite the importance of the fruit of this tree, only one paper at the molecular level has been published in Mexico, and possibly in America, to date. For this reason, the purpose of this research was to study the genetic variability of nanche trees that grow under both wild and semi-cultivated conditions in the state of Tabasco, Mexico. Molecular determinations were carried out in the Laboratorio de Genómica of the División Académica de Ciencias Biológicas (DACBiológicas), Universidad Juárez Autónoma de… More >

Abstract Ango is the main species of fruit in the state of Campeche, Mexico, due to the economic benefits generated because of its production and marketing. Among the biotic problems that affect this crop in the region are weeds, which involve a heavy economic investment for their management. Under this scenario, it is important the development of ecological weed studies to generate information that help us to design strategies for managing the problem. During January to June 2010 a floristic study was developed on the population of weeds that compete with mango in the locations of Cayal and Castamay, at the… More >

Abstract Two accessions of wild grapevines (Vitis spp.) native to Puebla State, Nealticán and Teziutlán, and other two native to Temascaltepec (1 and 2), Mexico State, were cultured in vitro using both Murashige-Skoog (MS) and woody plant medium (WPM) mediums. There were no differences between mediums for shoot generation. However, differences were shown among accessions for explant vigour, callus development, number of roots, leaves and nodes per explant. Rooting was evaluated only in MS medium by adding naphthalene acetic acid (NAA), indole butyric acid (IBA) or indole acetic acid (IAA) at 0.5 mg/L. With the exception of Temascaltepec 2, NAA generated… More >

Abstract The southeast region of the “Estado de México” is a transitional floristic zone. The municipalities which constitute are: “Tenancingo”, “Villa Guerrero”, “Malinalco”, “Zumpahuacán”, “Ixtapán de la Sal”, “Tonatico”, “Coatepec Harinas”, “Almoloya de Alquisiras” and “Texcaltitlan”. They present wood of Pinus, wood of Abies, wood of Quercus, mountainous mesophyll wood and deciduous rainforest as the main kind of vegetation. Our objective was to obtain a list of trees and bushes, which can have a potential ornamental use, in the southeast of that state. The botanical material was gathered with the conventional techniques during bimonthly trips to the studied area from June… More >
