-
Fiber Quality and Maturity Stage
The optimal time to harvest fiber flax aligns with a specific stage of plant maturity, typically when the lower portion of the stem begins to turn yellow while the upper portion remains green. Harvesting prior to this stage results in immature fibers, lacking strength and pliability. Conversely, delayed harvesting leads to over-retting of the fibers, weakening them and reducing their commercial value. Precise assessment of stem color and fiber characteristics is crucial for determining harvest readiness. For instance, manual fiber testing (breaking a stem to examine fiber separation) provides a practical indicator of maturity.
-
Seed Yield and Moisture Content
Harvesting seed flax requires a different set of considerations, primarily focusing on seed moisture content and maturity. Optimal seed yield is achieved when seeds have reached physiological maturity and moisture content has dropped to acceptable levels (typically below 10%). Harvesting prematurely results in shriveled, immature seeds with reduced germination rates. Delayed harvesting increases the risk of seed shattering, leading to significant yield losses. Seed color and firmness are useful indicators of maturity, supplemented by moisture content measurements.
