Abstract

Pinus radiata needle primordia were examined for ultrastructural features of their epidermal cells. Epidermal cells consisted of thin walls, a thin cuticle over the outer tangential wall, plasmodesmata in all except the outer tangential wall, moderately dense cytoplasm with poorly differentiated plastids, abundant mitochondria, dictyosomes and rough endoplasmic reticulum, cortical microtubules, and several small vacuoles. A prominent nucleus with often two or more nucleoli was characteristic of these cells.
