Ontogenesis and variation of wood ‘parenchymatization’ in Cochlospermum vitifolium (Bixaceae)
IAWA JournalSummary Axial parenchyma proliferation (non-lignified parenchyma) in wood has been characterized for only a few species. In the present study, we characterized the proliferation, ontogeny, and seasonal variation of wood axial parenchyma in Cochlospermum vitifolium (Bixaceae). This study included material from natural populations from different sites in
