ARAUJO, A.V. et al. Germination, vigor and sanity of "fava d'anta" (Dimorphandra mollis Benth.) seeds obtained from fruits collected both in the soil and in the plant. Rev. bras. plantas med. [online]. 2009, vol.11, n.2, pp.170-175. ISSN 1516-0572. http://dx.doi.org/10.1590/S1516-05722009000200010.
The aim of this work was to evaluate the physiological and sanitary quality of seeds obtained from mature fruits collected in the soil and in "fava d'anta" plants. Dimorphandra mollis constitutes an endangered medicinal species native to cerrado and presents fruits rich in rutin. The experimental design was completely randomized, with 10 replicates. Each replicate consisted of a gerbox containing 15 seeds each. Physiological quality was assessed through germination and vigor tests by evaluating germination percentage, germination velocity index (GVI), and primary root dry matter. Sanitary quality was evaluated by identifying pathogenic microorganisms associated with the seeds, as well as their occurrence percentage in each plot. The identified fungi belonged to the genera Fusarium, Alternaria, Aspergillus, Cladosporium, Colletotrichum, Helminthosporium, Nigrospora, Penicillium, Phoma and Phomopsis. Seeds from fruits collected in the soil were more contaminated by pathogenic agents and presented lower germination (56.67%), vigor and health than seeds from fruits collected in the plant.
