XVI International Botanical Congess

This work was accomplished with objective of develop methodologies for the assexual propagation, being the first stage of the research involved cutting branches rooting. Work methodology consisted: (i) cutting branches formation of its median parts, (ii) test of pre-flowering (nov/98-TI) and post-flowering (jan/99-II) times, (iii) use of sandy substratum in shaded environment, irrigated, (iv) use of indolebutyric acid (IBA) to the rooting test in the concentrations (1000): 0, 1, 2, 3, 5 and 10 ppm, (v) statistical analysis used Tukey's Test and transforming observed values (X) in arcsen.rootX/100. The results demonstrated the good rooting of the branches even without IBA presence: 50.64%(TI) and 37.59%(TII). The better percentage was 1000 ppm in TI (61.11%). The variation and correlation coefficients were: VC=10.1% and r2=0.7. Equation model: Y=51.7-3.1X-0.13X2.
