Abstract
AbstractAccording to the Liebieg's law—in many regions of Europe, the main limiting factor that affects very often flax yield are weather conditions (precipitation). Resistance to drought stress of 51 flax genotypes was evaluated in pot trials (2002–2012). Controlled drought stress (62.5% optimal soil humidity) caused a decrease in fiber yield by 39.7–49.3% and a substantial drop in quality. Among the tested cultivars, the ones that gave relatively promising yields in conditions of water deficit were: Sara [PL], Ilona [NL], Modran [PL], Escalina [NL], Luna [PL], Alizĕe [FR], Artemida [PL], Selena [PL], Modran [PL], Nike [PL], and Venica [CZ]. Relatively good yields of fiber for these varieties were the result of the good yields of straw.In field trials carried out on two types of soil (pseudosolic and black soil), the highest fiber yield with good quality was obtained using: (1) sowing density of 2 800 seeds m−2, (2) row sowing, (3) harvesting time at green-yellow maturity stage (BBCH 83). Higher plant densities using row sowing resulted in higher fiber content (% in straw) together with better quality (tex). Earlier harvest times (BBCH 75, BBCH 79) allowed for obtaining very thin fiber. The content of pectin and lignin in the fiber increased with harvesting delay.Keywords: fiber flaxdrought stresscrop managementfiber yieldfiber qualityflax cultivars
