The spatial-temporal dynamics of an in vitro radicular system Typha domingensis for the development rhizofiltration technologies, with potential use as a phytotreatment eutrophicated water, were studied first time roots seedlings and rhizotron systems. effect indole-3-acetic acid (AIA) combination kinetin (CIN) or 6-benzylaminopurine (BAP) on cultivated light dark three systems rhizotrophic regime screening dynamic rhizogenic lines, by weekly allometric measurements length number roots,...
Fusarium equiseti strain FCHE and oxysporum FCHJ were isolated from the roots of wilting habanero pepper (Capsicum chinense Jacq.) seedlings with root rot. Toward developing a biorational control these serious phytopathogenic strains, ethanolic (EE) aqueous (AE) extracts different vegetative parts 40 tropical native plants Yucatán Peninsula screened for antifungal activity. Extracts six out assayed effective, most inhibitory studied further. EEs Mosannona depressa (bark stems roots),...
A protocol for the induction of hairy roots on somatic embryos rhizoclones from Typha domingensis seedlings grown in hydroponic rhizotron systems was established first time. Rhizogenesis induced through agrotransformation oblong and scutellar states development using K599, LBA9402, A4 strains Agrobacterium rhizogenes. The transfection to performed by cocultivation a Murashige Skoog mineral medium at 50% strength (MS0.5), dark, 28 ± 2 °C 72 h. In contrast nontransformed that did not exhibit...
Plant extracts are a valuable alternative for the control of phytopathogenic fungi in horticultural crops. In present work, vitro antifungal effect ethanol and aqueous from different vegetative parts 40 native plants Yucatan Peninsula on Curvularia lunata ITC26, pathogen habanero pepper (Capsicum chinense), effects most active postharvest fruits were investigated. Among these, Mosannona depressa (bark stems roots) Piper neesianum (leaves) inhibited 100% mycelial growth C. lunata. The three...
Sustainable methods of propagation Typha domingensis through somatic embryogenesis can help mitigate its current condition ecological marginalization and overexploitation. This study examined whether differentiation up to coleoptilar embryos could be obtained in an embryogenic line proliferated with light high auxin concentration.Murashige Skoog medium at half ionic strength containing 3% sucrose 0.1% ascorbic acid was used for the three phases. Induction started aseptic 9-day-old germinated...
Water quality indicators have been tied to natural or man-made surface hydraulic connection (SHC) conditions. Among these, temporally connected lakes (TCL) are intermediates between isolated (IL) and permanently (PCL). Therefore, the aim of this study is answer if water can estimate possible overlap two opposed conditions SHC (IL PCL) with intermediate one in similar modifications level regulation at basin level. nine variables sampled six three mentioned, chlorophyll a (Chl-a), Secchi disk...
An exploratory experimental design was developed to establish a model for Vallisneria americana Michx. following conventional in vitro culture procedures aquatic vegetation. The included five experiments with stages of presterilization or washing 0.1% Tween 20 R , sterilization NaClO and poststerilization explants (leaf base, rhizome, caulinar apex seeds), monophasic biphasic nutrient media. Leaves rhizo-mes were sterilized 0.3 0.6% NaClO, contact times 2.5 5 min. Both cultured gellified...
El enriquecimiento de nutrientes es un factor estrés involucrado en la declinación vegetación sumergida. Sin embargo, sensibilidad fisiológica o toxicológica los genotipos varía debido a las interacciones microbióticas y el desbalance fisicoquímico del agua, cuales han sido abordadas mediante una aproximación reduccionista experimentos controlados. objetivo estudio fue evaluar, modelo cultivo in vitro Vallisneria americana, diferentes fuentes concentraciones N sobre supervivencia crecimiento...
La pesquería del tiburón en México representa un importante recurso, existen más de 376 especies tiburones vivientes y la mitad son importancia para las pesquerías. Existe una gran demanda recurso ya que es útil diversos aspectos. El trabajo se realizó a lo largo costa estado Tabasco, contando con colaboración los pescadores distintas sociedades cooperativas polos pesqueros. objetivo fue determinar tienen comercial región. En cada zona desembarco realizaron registros biométricos...
La captura comercial del ostión Golfo ("Crassostra virginica") es una actividad muy importante que ubica a México en el 6° lugar nivel mundial. En estado de Tabasco la pesca constituye segunda económica y se encuentra entre los recursos pesqueros más importantes. este trabajo analizaron las capturas acuerdo sus volúmenes totales anuales, determinó abundancia recurso bancos ostrícolas aplicó Análisis Precaución.
To distinguish between the stress of Vallisneria americana caused by increases either in molar N:P relation (N-NO3 and P-H2PO4) or concentration nutrients (CN), nutritional regimen (NR) was examined means two randomized factorial experiments on plants cultured vitro modified MS medium. The first (RN1) crossed 16, 20, 24 CN (%) 25, 50, 100; while second (RN2) evaluated relations 48, 60, 72, percentages 3.125, 6.25, 12.5, 50. mechanism resistance to factor with decrease regeneration viability...
El cacao es un arbol tropical originario de America, su fruto se usa en la elaboracion del chocolate y sus derivados. La propagacion realiza por via sexual o semillas, adicionalmente propaga enraizamiento estacas e injertos. En actualidad tambien emplea embriogenesis somatica para clonal cacao, cual puede repetirse varias veces, lo que contribuye al incremento formacion embriones somaticos; el uso sistema inmersion automatico, incrementar produccion somaticos secundarios. Por anterior,...
Eutrophication-resistant phytoplankton communities in freshwater ecosystems have a novel lipid potential to contribute the development of tropical regions. The question that arises due unsustainability their eutrophicated waters is how recognition lipids resident progresses. Our aim was provide an overview pico-, nano- and micro-cellular with focus on eutrophic ecosystems. Using Preferred Reporting Items for Systematic Reviews Meta-Analyses (PRISMA) framework, global Latin American...
Background. The sustainable methods of propagation for Typha domingensis through somatic embryogenesis can help to mitigate its current condition ecological marginalisation and overexploitation. Then, the hypothesis established that variation concentration auxin light conditions in sequential stages culture generate different morphogenetic routes be monitoring by morphohistological markers.
