| Abstract:
- Arbuscular Mycorrhizal Fungi in Sucupira-Preta (Bowdichia virgilioides H.B.K.) and Paratudo (Tabebuia caraiba (Mart.) Bur): Effect of Substrata and Phosphorus Fertilization in the Colonization The savannah is one of the great natural reservations of biotic resources of Brazil, concerning fauna and flora, being rich in medicinal plants of popular use. The study of these native species, in relation to the propagation, in order to give subsidies to the rational plantings and the vegetate of extraction and environmental preservation areas, can support an efficient and not predatory exploration. The objective of this work was to evaluate the effect of different substrata and phosphorus fertilization in the mycorrhizical colonization of the medicinal species paratudo (Tabebuia caraiba (Mart.) Bur) and sucupira-preta (Bowdichia virgilioides H.B.K.). The experiment was installed in the greenhouse of FAMEV/UFMT with experimental design entirely randomic in factorial outline 4x2, being four substrata and two types of phosphorus fertilization. Roots of the two species were collected for evaluation of the mycorrhizical colonization in the Laboratory of Soil Microbiology of FAMEV/UFMT and the estimate of the colonization was accomplished by the the squared plate method. The colonization by arbuscular mycorrhizical fungi was verified in the medicinal species paratudo and sucupira-preta in averages of colonization of 9,1% for the two species, and in the conditions that the study was carried out, the substrata influenced in the mycorrhizical colonization. | |
