Comportamiento de un fulvato de calcio en dos especies (Lilium nashville y Lilium pollyanna) en la calidad de flor de corte. por Arredondo Pastrana, Diana Marisol

“…ABSTRACT Two different species of Lilium spp. were produced under different environment to be evaluated with 6 and 7 treatments of calcium fulvate dosages plus a witness and were compared between them with the main purpose of enhance its quality as cut flower and increase its competitiveness into markets cannot face due to the short time its shelf is exposed. First experiment was made at Universidad Autónoma Agraria Antonio Narro (UAAAN) culturing the specie Lilium nashville and evaluating the performance of the diameter and length of the stem, the number of flower buds, and the length of bud flowers against each treatment and obtain the correlation between the calcium content; also the concentration of calcium, magnesium and iron for each container was measure with the help of an atomic absorption spectrophotometer VARIAN Spectr AA-5 per determinate the match between the elements when were absorbed by the plant. …”

Determinación de dosis infectiva vía oral de la cepa neolonesa de formas de Trypanosoma cruzi (Chagas, 1909) a nivel experimental en modelo murino por Delgado Garduño, Jorge Andrés

“…Likewise, histological sections and transmission electron microscopy (TEM) were performed from infected tissue of the mice that died and those that were sacrificed and nests of amastigotes of T. cruzi were observed in the treatment with the highest concentration (1.5 million cells/mL), so the oral infection was confirmed for a second time. An analysis of variance with the Tukey test determined that there is no significant difference between the treatments. …”
