Abstract:

It is generally believed that the seedling of palmyra palm (Borassus flabellifer Linn.) is difficult to transplant and hence requires directsowing. This hinders mass propagation and plantation of this species. Its propagation is mostly through natural means, and hence palm trees are found to grow scatteredly. At present, palmyra palmhasbeen recognized as a priority species for raising plantations in the coastal embankment. This study has been undertaken to develop technique for raising palm seedlings. Investigations suggest that the bed mixture comprising 50% soil, 25% sawdust, 20% cowdung and 5% ash was the best, where tire average elongation of germtubes and coleorhiza/root-sheath was 37.3 cm by 7 weeks, the mixture depth of 38.1 cm wassufficient to accommodate theircumulative growth. These elongated germtubes could be removed from the temporary bed after 7 weeks of sowing seeds, when the tip of emergent coleoptile is visible on the surface of the bed. Rootlets were also found to occur in the root-sheath of all tire germtubes by that time. These germtubes were then detached from theirseeds and transplanted immediately into suitable polybags of22.9 cm x 30.5 cm size. All the transplantated seedlings survived and the emerging leaflets of these seedlings turned to green within a week after transplantion. The mortality of early and late trasplanted seedlings was 11% and 25% respectively. Germtubes were found to elongate up to 82.6% within 4 weeks after sowing seeds. On the other hand, more than 50% elongation of the coleoptile was observed during the 5-7th weeks after sowing.
