Dinámica poblacional de hongos micorrízicos en suelos arroceros, afectados por inundación en la zona de Babahoyo

The rice is a grass grown in the coastal region of Ecuador, mainly in the provinces of Guayas and Los Ríos, which cover the majority of hectares planted. In this type of crop the level of water sheet can vary from 2.5 to 15 centimeters, so the water factor is considered the first and often the greatest restriction for the different types of microorganisms that can be found in the environment of the rice field. The term mycorrhiza comes from the Greek myces, which means fungus and rhiza, whose meaning is root, and represents the mutualistic association between some fungi (mycobionts) and the roots of plants (phytobionts), mycorrhizae are classified into three groups that are following: ectomicorrizas, endomicorrizas and ectoendomicorrizas. These fungi occur in approximately 90% of plants, so it is common to find them in all the world's ecosystems and, therefore, in different latitudinal gradients. The mycorrhizal inoculum is present in almost all soils and factors such as the release of nitrogen compounds from fertilizers, acid rain, soil exposure to high concentrations of atmospheric carbon dioxide, and ozone pollution, can affect in the diversity, abundance and functioning of mycorrhizae communities. The activity of mycorrhizae allows an improvement and an increase in the assimilation of nutrients and water in plants, while in relation to the soil, its colonization allows erosion to be avoided. The inoculation of mycorrhizae in rice cultivation, cause an effect on the plants allowing them to increase their values of biomass, yield and foliar nutrients, unlike those that are not treated with the fungus
