Abstract
Sri Lanka is a country which consists with number of endemic aquatic plants. These endemic aquatic
plants are having high demand in aquatic plant industry (Galapitagedra, n.d.). Due to the lack of
effective propagation methods plant collectors collect plant from wild to fulfill the market demand.
It leads to the depletion of natural plant stock and bio diversity. Lagenandra species only can observe
in Sri Lanka, Southern India and Bangladesh (Dassanayake et. al., 2001). In Sri Lanka there are seven
species and six species are considered as endemic. Red List of International Union for the
Conservation of Nature in 2013, categorized five of those endemic species under the highly
threatened category. Main purpose of this study is to develop a proper method for micro propagation
of Lagenandra ovata and Lagenandra lancifolia to overcome inadequate supply and depletion of
natural plant stock. Present study was carried out to evaluate effect of different hormone
concentrations in basal media for shoot initiation and multiplication of rhizome explants,to identify
the best explant of L. lancifolia for micro propagation and to identify the best medium for L. ovata
seed culture.
