Initial growth of <i>Enterolobium contortisiliquum</i> (Vell.) Morong. seedlings under different luminosity levels

Abstract

The effect of different levels of luminosity in the initial development of Enterolobium contortisiliquum (Vell.) Morong. seedlings was evaluated. The studied levels were full light, 20, 40, 60 and 80% of shading in relation to the full light of the day. The survival, height and diameter, in function of shading in the 7, 14 and 25 days after the sowing, and the length of the root and the dry weight of the root and the aerial part were evaluated at the end of the experiment. The full light and 20% of shade showed the best results.
