Capacidad fitorremediadora de las especies de flora herbácea silvestre con mayor valor de importancia en la zona de pasivos mineros El Sinchao, distrito de Chugur, provincia de Hualgayoc, Cajamarca – Perú 2017
Universidad Privada del Norte, 2018Co-Authors: Dávila Mego, Nancy Karina, Walter Villegas, Lorena ChabeliAbstract:RESUMEN Se determinaron las especies de flora herbácea silvestre con capacidad fitorremediadora originarias de la zona de pasivos mineros el Sinchao, ubicado en el distrito de Chugur, Provincia de Hualgayoc, donde se realizaron los análisis en las especies Calamagrostis tarmensis, Paspalum bonplandianum, Carex pichinchensis, Lachemilla orbiculata y Juncus conglomeratus seleccionadas por su alto valor de importancia en la zona, posteriormente mediante el coeficiente de correlación de Pearson se logró determinar la relación entre la concentración de metales en el suelo y las plantas. Asimismo, se calculó el Factor de Traslocación y Factor de Bioconcentración, lo que permitió indicar si la planta es fitoestabilizadora o fitoextractora de Aluminio, Arsénico, Plomo, Cromo, Cobre, Cadmio, Magnesio, Manganeso, Zinc, Estroncio, Antimonio, Talio, Hierro, Mercurio, Níquel y Estaño. Por otro lado se obtuvo una base de datos de la zona Las Gardas, la cual contribuyó como referencia para comparar la acumulación de las plantas tanto en una zona con pasivos y otra zona sin alteraciones. En la investigación se identificó que la especie Paspalum bonplandianum, acumula la mayor cantidad de metales pesados (mg/kg), como el Aluminio (2844.6), Mercurio (0.3), Antimonio (13), Estaño (1.4), Zinc (760.2), Cromo (3.86) y Níquel (3.59). Asimismo, la concentración de metales pesados se da en la parte de la raíz de todas las especies, a excepción de la Lachemilla orbiculata donde se observó que es en el tallo. Finalmente, mediante los TF y BCF se estableció que la especie Calamagrostis tarmensis, Paspalum bonplandianum, Carex pichinchensis, Lachemilla orbiculata y el Juncus conglomeratus serían especies fitoextractoras de Mg y Mn; igualmente, Lachemilla orbicula también sería fitoextractora del Sr y el Zn. Por otro lado Calamagrostis tarmensis se podría aplicar en técnicas de fitoestabilización para el Ti, asi como Paspalum bonplandianum para el Sb, Zn y Cr, la especie Carex pichinchensis para Zn, la especie Lachemilla orbiculada para el Cd y Mn y finalmente el Juncus conglomeratus para el Cd, Cr y Zn. PALABRAS CLAVES: Fitorremediación, valor de importancia, Factor de Traslocación, Factor de Bioconcentración, fitoestabilización y fitoextracción.ABSTRACT The species of wild herbaceous flora with phytoremediation capacity originating in the Sinchao mining passive area, located in the district of Chugur, Province of Hualgayoc, where the analyzes were carried out on the species Calamagrostis tarmensis, Paspalum bonplandianum, Carex pichinchensis, Lachemilla, were determined. Orbiculata and Juncus conglomeratus selected for their high value of importance in the area, later using the Pearson correlation coefficient was able to determine the relationship between the concentration of metals in the soil and plants. Likewise, the Translocation Factor and Bioconcentration Factor were calculated, which allowed to indicate whether the plant is phytostabilizing or phytoextracting of Aluminum, Arsenic, Lead, Chromium, Copper, Cadmium, Magnesium, Manganese, Zinc, Strontium, Antimony, Thallium, Iron , Mercury, Nickel and Tin. On the other hand, a database was obtained from the Las Gradas area, which contributed as a reference to compare the accumulation of the plants both in one zone with liabilities and another zone without alterations. In the research it was identified that the species Paspalum bonplandianum, accumulates the highest amount of heavy metals (mg / kg), such as Aluminum (2844.6), Mercury (0.3), Antimony (13), Tin (1.4), Zinc (760.2) , Chromium (3.86) and Nickel (3.59). Also, the concentration of heavy metals occurs in the root part of all species, except for the Lachemilla orbiculata where it was observed to be in the stem. Finally, through TF and BCF it was established that the species Calamagrostis tarmensis, Paspalum bonplandianum, Carex pichinchensis, Lachemilla orbiculata and Juncus conglomeratus would be phytoextractant species of Mg and Mn; likewise, Lachemilla orbicula would also be a phytoextractor of Sr and Zn. On the other hand Calamagrostis tarmensis could be applied in phytostabilization techniques for Ti, as well as Paspalum bonplandianum for Sb, Zn and Cr, the species Carex pichinchensis for Zn, the species Lachemilla orbiculada for Cd and Mn and finally the Juncus conglomeratus for the Cd, Cr and Zn.

'Springer Fachmedien Wiesbaden GmbH', 2021Co-Authors: Lezama Oribe, Jhony Miguel, Saldaña Vega, Dante Orlando, Velásquez Marín, Magda Rosa, Sánchez Peña, Marco AlfredoAbstract:ABSTRACT A study was carried out to identify herbaceous flora with greater importance value and evaluate its potential capacity of phytoremediation in mining-contaminated soils. The study analyzed three soil samples, two root samples, two stem samples of each species of higher importance value in an area of eighty square meters. Therefore, the bioconcentration factor (BCF) was calculated for the root of the species Paspalum tuberosum, which is silver accumulator and is excluding arsenic, copper, lead, antimony, zinc, aluminum, and iron. The Pennisetum clandestinium is a silver accumulator and is exclusive of arsenic, copper, lead, antimony, aluminum, and iron. The Trifolium repens showed a BCF in the root that excludes all metals. The concentration of heavy metals in the aerial part of the Paspalum tuberosum, Pennisetum clandestinium, and Trifolium repens, presented an area (BCF) excluding all metals. The heavy metal translocation factor (TF) in Paspalum tuberosum and Pennisetum clandestinium does not effectively transfer heavy metals from the root to the aerial part of the plant. Trifolium repens showed a hyperaccumulation (TF) of silver, arsenic, copper, and zinc

El Trifolium repens mostró un (TF) hiperacumulador de Plata, Arsénico, Cobre y Zinc. PALABRAS CLAVE: factor de traslocación, factor de bioconcentración, fitoestabilización, hiperacumulación.A study was carried out whose purpose was to determine the identification of herbaceous flora with greater importance value and evaluation of its phytoremediation capacity in soils contaminated by mining. The study analyzed three soil samples, two root samples, two stem samples of each species of greater importance value, in an area of eighty square meters. Therefore, the root bioconcentration factor (BCF) of the Paspalum tuberosum species was calculated, which is an accumulator of Silver and is exclusive to Arsenic, Copper, Lead, Antimony, Zinc, Aluminum and Iron. Pennisetum clandestinium, is an accumulator of Silver and is exclusive to Arsenic, Copper, Lead, Antimony, Aluminum and Iron. Trifolium repens, showed an exclusive root BCF to all metals. The concentration of heavy metals in the aerial part of Paspalum tuberosum, Pennisetum clandestinium and Trifolium repens, presented an aerial (BCF) excluding all metals. The heavy metal translocation factor (TF) in Paspalum tuberosum and Pennisetum clandestinium does not effectively transfer heavy metals from the root to the aerial part of the plant. Trifolium repens showed a hyperaccumulator (TF) of Silver, Arsenic, Copper and Zinc. Keywords: Translocation factor, Bioconcentration factor, phytostabilization, hyperaccumulation

atypical foliar anatomy related to kranz syndrome in Paspalum inaequivalve and Paspalum microstachyum poaceae panicoideae paniceae
Flora, 2009Co-Authors: Sandra S Aliscioni, Silvia S. DenhamAbstract:Abstract Paspalum L. is a large and complex genus, enclosing more than 300 species, whose boundaries and infrageneric classification are still being studied. Recent phylogenetic analyses suggest that Paspalum inaequivalve Raddi and Paspalum microstachyum J. Presl, from the Inaequivalvia informal group, should be excluded from Paspalum . Focused on the unclear taxonomic position of P. inaequivalve and P. microstachyum , their leaf anatomy was studied, and some atypical features related to C 4 photosynthesis were found. This atypical Kranz syndrome is the aim of this research. Transverse leaf blade sections from fresh and herbarium material of P. inaequivalve were studied by light, fluorescence, and transmission microscopy. Additionally, sheaths and culms of P. inaequivalve and leaf blades of P. microstachyum were observed by light microscopy. δ 13 C isotope discrimination was determinated for P. inaequivalve . We compared our results with available anatomical data from related taxa. As well as typical mesophyll cells (PCA) and mestome sheath cells (PCR), a third type of cells, here called ‘globose parenchymatous cells’, was observed in leaf blades of P. inaequivalve and P. microstachyum . These cells are placed externally to the mestome sheaths of the first and second vascular bundles, they have thin walls, with no developed suberine lamella, few chloroplasts with 1–2 starch grains, thylakoids not organized in grana, and a large central vacuole. The globose parenchymatous cells represent a novel trait in P. inaequivalve and P. microstachyum , further supporting the close relation between both species and their exclusion from the genus Paspalum . This atypical Kranz syndrome has not been described in Paspalum before, but the globose parenchymatous cells here described resemble the distinct cells considered as remnants of the outer parenchymatous sheath described for Anthaenantiopsis , some sections of Panicum L., and Chaetium Nees, providing possible taxonomic significance.

rachis of the genus Paspalum l poaceae panicoideae paniceae anatomy and taxonomic significance of the primary branches of the inflorescences
Flora, 2008Co-Authors: Sandra S Aliscioni, Silvia S. DenhamAbstract:Abstract Infrageneric classification of Paspalum is mainly based on characters of the inflorescence and spikelets. Some of the inflorescence characters usually used are the width and external morphology of the rachises of the racemes. Nevertheless, morphological terminology used in the literature is frequently imprecise. We examine the internal structure of the rachises of the racemes in Paspalum to: (a) compare it with the anatomy of a vegetative culm, (b) precisely describe its variation within the genus to search for features that could be used in taxonomy or phylogeny. Species representative of all subgenera and informal groups were studied. Serial transversal sections were made and analyzed using light microscopy. Many distinctive characters from the central keel and lateral wings allow to distinguish six anatomical types of rachises: Type I is the most frequent in the genus, being present in species of all subgenera; Type II characterizes Conjugata, Dissecta and Disticha groups; Type III is exclusive of subgenus Harpostachys; Type IV is common in Ceresia subgenus and it is also present in two species of Gardneriana group and in Paspalum guttatum of Erinatha group; Type V is present in Bonplandiana and Racemosa groups, and Type VI is exclusive of Paspalum falcatum of Falcata group. Rachises of the racemes are undoubtedly caulinar structures although many species present flat rachises, with vascular bundles arranged in one only row and with abundant photosynthetic tissues. This study permits to differentiate, by means of anatomical characters, rachises that are morphologically similar or undistinguishable. Some anatomical types of rachises are related to taxonomic groups or subgenera, stressing their taxonomic value. Using anatomical characters of the rachis of the Paspalum raceme can improve phylogenetic analyses.

contribucion a la filogenia del genero Paspalum poaceae panicoideae paniceae
Annals of the Missouri Botanical Garden, 2002Co-Authors: Sandra S AliscioniAbstract:Paspalum L. has approximately 330 species and a large geographical distribution, mainly in tropical and subtropical regions of America. Due to the morphological variability among the species, different authors have proposed dividing the genus into subgenera, sections, or informal groups. A cladistic analysis of Paspalum was conducted using anatomical foliar and exomorphological characters to test its monophyly and its phylogenetic relationships among representative species. The degree of character homoplasy was analyzed in order to estimate the diagnostic value of anatomical characters among groups. For the cladistic analysis, 47 species of 27 groups established by Chase, with modification established by Cialdella et al. and Morrone et al., and 36 exomorphological and anatomical foliar characters were considered. The data matrix was analyzed with Nona and Pee-Wee, parsimony programs using equal weights and implied weighting. The present phylogenetic analysis confirms that Paspalum is a paraphyletic group and shows close relationships with Axonopus and Thrasya in Paniceae.

anatomia ecologica de algunas especies del genero Paspalum poaceae panicoideae paniceae
Darwiniana, 2000Co-Authors: Sandra S AliscioniAbstract:Paspalum L. has a large number of species with a wide morphological variability and extensive geographical distribution. Species of the genus grow in very diverse habitats, from humid or aquatic environments to dry places with clay or sandy soils, frequently saline. Given the diversity of habitats where the species of Paspalum occur, foliar anatomical characters were studied in order to explain different adaptative strategies. A description of the foliar anatomy of the genus is given, and several characters are discussed in relationship to the habitat.
