The main objective of this research was to investigate
the effect of agronomic practices and site condition on flax ontogenesis and
fiber yield and its quality. A method based on osmotic degumming
was applied for objective evaluation of the quantity and the quality of fiber
in the raw material. In this process, fibrous plants were subjected
to the treatment with water that flows continuously in order to extract fibres
from plants without influencing natural properties of the fibre. The fibre
obtained according to this method is characterised by a colour, delicacy and thinness adequate to
input raw material.
The studies focused on growth dynamics and
development of a fiber flax plant assessed according to the BBCH scale as well
as evaluation of plant morphogenesis and functiogenesis.
The research of flax ontogenesis at the INF has been conducted as a part of
study on agronomic model of flax fiber life cycle. In conditions of field
trials carried out in 2005 the best yield and quality of flax fibre was obtained when flax had been sown with the density
of 140 kg/ha and harvested in green-yellow maturity phase.
