Temporal variation in rooting of Annickia chlorantha leafy stem cuttings uri icon

abstract

  • The effects over time of exogenous auxins and substrate on rooting of leafy stem cuttings were simultaneously examined in Annickia chlorantha. The hypothesis that post-severance treatments and propagation environment do not temporally affect the rooting ability of leafy stem cuttings was rejected. Each of the four replicate blocks used consisted of 12 treatments from two crossed factors, substrate x auxins. Time (weeks) after insertion of cuttings in nonmist propagators was used as the third factor. Substrate x auxin x time had highly significant (P = 0.0022), whereas substrate x time and auxin x time had non-significant (P = 0.0518-0.0549) effects on rooting percentage, respectively. Substrate and auxin did not influence rooting ability. Time had highly significant (P < 0.0001) effects on rooting ability. Contrasts constructed with the different factors tested on rooting percentage allowed the dissection of the rooting period into three phases.
