EMERGENCE OF Clitoria fairchildiana R.A. Howard SEEDLINGS AT DIFFERENT SUBSTRATES

Abstract

Clitoria fairchildiana R.A. Howard, commonly known as faveira, is an arboreal species used for reforestation and recommended for the recovery of degraded areas. The bark of the eucalyptus tree in the composition of the substrate for the emergence of faveira seedlings is assessed. Seeds were placed in plastic boxes with sand, soil, eucalyptus bark, sand and eucalyptus bark (3:1; 1:1; 1:3), soil and eucalyptus bark (3:1; 1:1; 1:3) and sand, eucalyptus bark and soil (1:1:1; 1:2:1; 1:4:1) and maintained in a greenhouse. Percentage, emergence speed and biometry of the faveira seedlings were evaluated. The emergence of faveira seedlings is less affected by the eucalyptus proportion in the substrate (soil and/or sand) when compared to the seedlings´ strength. The most adequate substrates for the emergence of faveira seedlings are sand (A), ground eucalyptus bark (C), Soil (S) and (S) + C (3:1), S + C (1:3), A + C (3:1) and A + C (1:3).
