Abstract

PIANA, Z.; CAVARIANI, C.; TILLMANN, M.A.A.  and  MINAMI, K.. Influence of water levels of the substrate on the rooting of white ivy (Evolvulus pusilus) cuttings. Sci. agric. (Piracicaba, Braz.) [online]. 1994, vol.51, n.3, pp. 470-473. ISSN 0103-9016.  http://dx.doi.org/10.1590/S0103-90161994000300015.

This investigation was conducted in order to verify the influence of water content of the substrate on the rooting of white ivy (Evolvulus pusilus L.) cuttings. The effect of five water levels of the medium soil x sand (3:1-20, 40, 60, 80 and 100% retention capacity) on the rooting of white ivy was studied using four replicátions to verify the percentage of rooted cuttings. Each replication included the rooting of 20 apical cuttings averaging 15 cm, introduced to the 6 cm depth, totalling 80 cuttings per treatment. The results led to the conclusion that the soil water content that promoted higher rooting was between 50 and 70% of the substrate retention capacity.
