El objetivo del presente trabajo fue la caracterización ultraestructural de metacercarias Diplostomum sp en Orestias luteus lago Titicaca, Puno, Perú. Se recolectaron 35 peces mediante muestreo no probabilístico los cuales fueron anestesiados con tricaina mono sulfonato (Tricaine-s®) y se les realizó necropsia para determinar el número por pez. Los parásitos extraídos fijaron conservaron su est...
Introduction: salinity is known as the most important inhibitor of seed germination of most plants and limits the establishment of plants in arid and semi-arid regions such as Iran. The first effects of salinity on plant growth are associated with reduced seed germination and lack of uniformity in plant emergence. Currently, identification and utilization of tolerant cultivars are one of the mo...
he remains of an extensive ancient agricultural system built and used by Andean peoples centuries ago are found throughout the vast high plain surrounding Lake Titicaca in the Andean countries of Peru and Bolivia (Figs. 1, 2). Raised fields are large elevated planting platforms which provided drainage, improved soil conditions, and improved temperatures for crops, The remains of prehistoric rai...
Water shortage is a critical problem touching plant growth and yield in arid semi-arid areas such as Iran. Plant hormones jasmonic acid (JA) play crucial role altering morphology response to stress. To investigate the effect of JA drought stress on grain some physiological biochemical characteristics quinoa cultivars, split-plot factorial experiment based randomized complete block design with t...
