Abstract:

    The pantropical Zingiberaceae are considered among the most threatened of the monocotyledonous flora in the Philippines as many of its endemic species are now on the brink of extinction. The flora includes the monotypic Leptosolena haenkei C. Presl listed under the vulnerable (VU) category of the Threatened Plants of the Philippines and Vanoverberghia sepulchrei Merr., which is under the other threatened species (OTS) category. This study examined the morphoanatomical features of these two species and produced a vegetative propagation scheme by determining the viability of ther hizome explants using 1-naphthalene-acetic acid (NAA) and n-2-furanylmethyl-1H-1-purine-6-amine (Kinetin) as plant growth hormones. They were treated with different concentrations and combinations of NAA and Kinetin. All treatments induced the viability of the rhizome explants. The results revealed that low concentration produced more viable and fairly viable rhizome explants than high concentration of NAA or Kinetin. Also, L. haenkei issaid to be more viable to V. sepulchrei in all of the eight treatments, X2(2, N = 160) = 22.71, p < 0.05, and this is because of many factors such as phenotypic variations among the two gingers and microclimatic factors.
