Abstract
In vitro seeds germination and plantlet establishment of Labisia pumila were studied in this report. The seeds obtained from the mature fruits of L. pumila were sterilized and cultured on Murashige and Skoog (MS) solid media supplemented with 1–3 μM of 6-benzylaminopurine (BAP) and 3% (w/v) sucrose. The presence of BAP in the medium significantly affects seeds germination. High percentage of seeds germination (up to 90%) was successfully achieved after 2 weeks of culture on medium supplemented with 2 μM BAP. Up to 70% of explants produced shoots through direct regeneration from newly emerged epicotyls after 5 weeks of culture. The average of 8.1 ± 1.0 shoots per explant obtained on media treated with 2 μM BAP. Seedlings were further transferred to growth media fortified with different types of cytokinin. Result observed after 12 weeks showed that medium supplemented with 1 μM zeatin (ZEA) promote the highest growth with an average of 2.9 ± 1.0 cm shoot length and 7.7 ± 3.2 leaves per explant after 12 weeks. In addition, medium added with 2 μM BAP and supplemented with 3–4% (w/v) of sucrose promote the best growth i.e., 3.0 ± 0.6 shoots per explant, 2.27 ± 0.2 cm length and 4.3 ± 0.5 leaves per explant.
