DETERMINATION OF THE PRESENCE OF MYCORRHIZAL FUNGI IN CHIA (SALVIA HISP?NICA L.) IN TWO LOCALITIES OF PARAGUAY

As an agricultural crop, Chia (Salvia hispanica L.) has an incipient importance in Paraguay and the presence of mycorrhizal fungi is a symbiotic association of high relevance for the crop. Experiments were carried out in two areas belonging to the departments of Itap?a and Misiones respectively. The study established the objective of determining the presence of mycorrhizal fungi in chia. Sowing was carried out in experimental trials in the above mentioned locations. Root fragments were extracted from the experimental units from 0 to 10 cm deep; they were taken to the Science and Technology Lab of the State University of Itap?a for the determination of the structures. It was possible to confirm the presence of arbuscules and hyphae in the analyzed samples corresponding to the environments involved, the structures were assumed to be similar, taking as variable the vesicles, the averages registered in the departments were statistically similar; indicating that the presence of mycorrhizal structures are the same in both environments.
