The structure of the thick wall of lignified fibre cells from the flowering stem of Lolium temulentum L. is described. The formation of wall layers is related to the period of cell elongation and to the presence or absence and state of development of organelles which are possibly involved in the formation of the cell wall.
It is suggested that while the fibre cells are still elongating, rough endoplasmic reticulum (RER) and dictyosomes associated with small, electron transparent vesicles are involved in the formation of the cell wall, whereas in fibre cells which are nearing the end of elongation, and those which have stopped elongating, it is suggested that microtubules, lomasomes and dictyosomes associated with large electron transparent vesicles and small vesicles with electron dense cores are involved.
The nomenclature for labelling wall layers as primary or secondary is discussed.
