Résumé:
The sanitary quality of forest seeds is one of the main factors for their germination
due to the losses caused by their deterioration, abnormalities, lesions in seedlings
and consequently the drastic reduction of seedling production in nurseries.
Alternative treatments based on plant extracts may eventually constitute an
alternative for the control of pathogens associated with seeds, with the reduction of
expenses for the production and production of nutrients for the chemical products.
This work has as main objective the efficiency of the different treatments with ginger
extract (germination) and the reduction of the incidence of fungi associated with
mulungu (Erythrina velutina) seeds. The mulungu seed health test was performed to
quantify and identify fungi associated with mulungu seeds using the Blotter Test
method, NEEGAARD, 1979. For the use of 500 mulungu seeds collected in the year
2018 and for the germination test in the year 1000 mulungu seeds collected in 2016,
submitted to a set of substrates - sand and vermiculite - for germination test and the
different concentrations of ginger extract, for both testicles: 0% ginger extract (T1);
25% -exclusion of ginger (T2); 50% -extraction of ginger (T3); 75% -exclusion of
ginger (T4) and 100% - extraction of ginger (T5) for one minute. After the analysis of
the mulungu seeds, it was observed a greater incidence for the genus Aspergillus. In
the germination, a vermiculite was superior to a sand, the difference in performance
and the movements were T2 - 25% of mulungu extract, T4 - 75% of mulungu extract
and T5 - 100% of extract of mulungu, thus obtaining 100% germination in these
treatments.
