Deskripsi

<p class="p1"><em>Gymnacranthera canarica</em> (King) Warb. is an exclusive <em>Myristica</em> swamp species endemic to the Western Ghats.  The <em>Myristica </em>swamp is a Critically Endangered ecosystem.  Studies were carried out to assess the viability, germination and storage behaviour of <em>Gymnacranthera canarica </em>seeds.  In the present study, it was observed that seeds have shown an initiation of germination after two weeks.  A maximum of 90% germination was recorded when the initial moisture content was 38.04 ± 1.75 %.  A decreased percentage (3%) was observed when the moisture content reached 14.26 ± 2.3 after 70 days of storage.  Seeds failed to germinate beyond this moisture level.  A desiccation study showed recalcitrant behaviour and seeds can be stored in lab conditions for up to two and half months.</p>
