Effects of plant growth regulators on the rapid proliferation of shoots and root induction in Spathiphyllum floribundum cv. Maya White

An efficient plant regeneration protocol was developed for rapidly propagating Syngonium podophyllum cv. Maya White, via shoot organogenesis. Shoot multiplication was induced on (MS) medium supplemented with 3-Indoleacetic acid (IAA), 6-benzylaminopurine (BA), kinetin and a-naphthaleneacetic acid (NAA). Rooting was induced on full- or half-strength MS medium supplemented with NAA and indolebutyric acid (IBA) and BA. The maximum mean number of shoots (3.2) was obtained from a single explant by the combined effect of 5.4 mu m NAA and 13.3 mu M BA. The longest roots and a minimum number of roots were produced in the medium without plant growth regulators. The shorter roots and the largest number of roots were observed in the medium supplemented with 2.7 mu M NAA and 4.4 mu M BA.
