Despite the economic potential of Atuna racemosa, its morphological measurements, seed storage behaviour and detailed seedling growth and development are not yet established. This study characterised the seed morphology, storage behaviour and germination pattern of A. racemosa seeds. Three hundred mature fruits from three accessions of the germplasm collection of the Institute of Crop Science, University of the Philippines Los Baños, were characterised. Seeds were morphologically characterised, tested for viability at fresh (~ 65%) and dry (~ 12%) moisture contents, planted and observed regularly for growth and development. A. racemosa seeds are relatively large in size with a length of 48.88 ± 1.56 mm, width of 37.56 ± 0.85 mm and thickness of 33.75 ± 0.92 mm. They are obovate to orbicular in shape. When dried, seeds lost their viability completely indicating recalcitrant seed storage behaviour. Framed according to the extended BBCH scale, the germination pattern is identified as cryptocotylar hypogeal; however, distinct and non-plastic features are present, such as formation of seven cataphylls prior to true leaf unfolding (BBCH 11) and emergence of radicle (BBCH 05) at the peduncle end of the seed.
