Winter and spring forms of Camelina sativa

Camelina sativa (L.) Crantz

Camelina sativa is represented by winter and spring forms that differ in their developmental cycle and environmental adaptation. Winter forms undergo vernalization and are characterized by high winter hardiness, whereas spring forms complete their growing season in 66–90 days.

In the reference 17 varieties crop Camelina, where this is mentioned in the description.

Spring forms of Camelina sativa complete their full developmental cycle in a single season, with seedlings capable of withstanding frosts down to –2…–10°C. Winter forms develop a leaf rosette in autumn, undergo a period of vernalization, and resume growth in the spring. They possess high winter hardiness, surviving temperature drops down to –20…–25°C even in the absence of snow cover.

Morphological differences of winter forms include the presence of pubescence, which facilitates economical moisture consumption; this, combined with the efficient use of autumn-winter precipitation, ensures high productivity under arid conditions. The biochemical composition of seeds from winter and spring forms varies in the concentration of flavonoids, phenolic acids, and the fatty acid profile.

Technological features of spring form cultivation involve spring sowing when the soil warms to +1…+2°C, whereas winter forms are sown in the autumn. Winter camelina is valued for its early maturity, which facilitates rapid field clearing, and its high competitiveness against weeds.
