Seed-flax variety CI. 2446 was planted at four different dates (Oct. 5, Oct 20, Nov. 5, Nov. 20) and four different densities (2250, 1800, 1350 and 900 plants/m^2) to study the effects on the fiber cell development at different growing stages. All traits, except the phloem thickness, of fiber cell showed no significant difference among different sowing densities.
