Abstract
This study aims to examine the in vitro propagation of Philodendron hederaceum “Lemon Lime”. The results showed that MS medium supplemented with 1.0 mg/l BA was suitable for the rapid multiplication stage, with the rate of shoot proliferation being 2.73 times, the shoots being 5.38 cm in height and the number of leaves/shoot was 4.33 after 6 weeks of culture. In the next stage, in vitro shoots were transferred to MS medium containing 0.25 mg/l IBA for rooting. Within five weeks of culture, 100% of shoots induced roots with a mean of 3.9 roots/plant and the root length was 11.04 cm. In the acclimatisation phase, plantlets achieved 100% ex vitro survival, increased by 2.19 cm in height and 1.96 leaves after four-week acclimatisation in a substrate composed of peatmoss:soil:coconut husk (1:1:1). These research results could be used to cultivate this plant with high proliferation rate and good commercial quality providing seedlings for the floriculture market in Vietnam.
