摘要

Xylem fibres were found to have retained their nucleus in 27 species of 17 genera of woody plants (trees, shrubs, climbers). These fibres were characterized by thick lignified walls with a narrow lumen and tapering ends. Their length and width varied among the species studied and were greatest in Phyllanthus emblica and least in Antigonon leptopus (a scandent shrub). Depending on the species, the fibres were either septate or nonseptate. Each compartment of the septate fibres was accompanied by a single nucleus. The nuclei of these fibres were oval to oblong or fusiform in shape. Accumulation of starch in the lumina of the nucleated fibres was a common feature in all the species. The occurrence of nucleated fibres and its possible significance arediscussed.
