MORPHOLOGICAL AND ANATOMICAL CHARACTERISTICS OF WILD AND IN VITRO OF Hoya parasitica Wall. ex Wight

Abstract

The Hoya parasitica Wall ex Wight is both an ornamental and precious medicinal plant. Along with the wild plants, in vitro H. parasitica plants created by plant tissue culture techniques were also interested in research to develop and exploit the genetic resources of this precious medicinal plant. The question is, what are the similarities and differences between the morphology and anatomy of wild plants and in vitro plants? In this study, the detailed characteristics of roots, stems, and leaves H. parasitica plants were analyzed by comparative morphological and anatomical methods. The wild H. parasitica plants and in vitro plants have similar morphological and microscopic structures of roots, stems, and leaves. The most obvious difference is that the wild H. parasitica plants have lateral roots and no hair-sucking; the in vitro plants have many white hair-sucking growing around the primary roots.
