RELATIONSHIP BETWEEN FERTILIZATION SOURCES IN THE PRODUCTION OF FURANOCUMARINE IN THE CROP OF CARAPIÁ (Dorstenia brasiliensis)

Abstract

The use of medicinal plants is widely common, above all, due to traditional knowledge. Among the medicinal species, Dorstenia brasiliensis is important for presenting furanocoumarins, which is a secondary matabolite related to various therapeutic functions. However, there are still no reports on the cultivation or even the relationship of fertilization in the production of this species. The work aimed to evaluate the formation of furanocoumarins and the dry and green weights of rhizomes in the culture of Carapiá (Dorstenia brasiliensis), under edaphoclimatic conditions of Palmeiras de Goiás under the effect of different sources of fertilization. The experiment was carried out in the municipality of Palmeiras de Goiás, at the State University of Goiás - Câmpus Palmeiras de Goiás, from November 2017 to August 2018. A completely randomized design with 3 treatments and 10 repetitions was adopted. The variables tested were the sources of fertilization of bovine, organomineral and mineral manure. When analyzing the relationship of the influence of fertilizer sources to green weight and dry weight, there was no significant difference between treatments, concluding that fertilization did not interfere with these factors. Regarding the interference of fertilization in the levels of psoralen, all treatments obtained statistical difference, and the sources of fertilization used resulted in the lower production of this metabolite. Likewise, the influence of fertilizer sources on the levels of baptapene resulted in a statistical difference between all treatments, so that treatments with fertilizers showed an increase in the production of this compound.
