control treatment (0 mg l−1IBA) was that which provided the bestresult, with an average of 4.5 roots formed and 7.9 cm in lengthafter a 60-day cultivation period, suggesting that there are pos-sibly optimal levels of endogenous regulators required for rootingpresent in the explant (Diwakaran et al., 2006). The levels and qual-ity of auxin have the greatest influence on rooting when workingwith plant species in vitro. Nevertheless, several species, partic-ularly herbaceous species, root easily under low levels of auxin,or simply in a basic medium without growth regulators (Gurelet al., 2011).
