The Effect of Different Salinity Levels on Germination Development of Some Flax (Linum usitatissimum L.) Varieties

Abstract

Salinity, which is one of the abiotic stress factors, severely restricts plant production as a result of\rthe negative effects of plants in different growth and development periods. Therefore, it is extremely\rimportant to determine the tolerance limits of plants to salinity in order to eliminate the limiting\reffect in terms of plant growth. Flax is an industrial plant that is used for multiple purposes and has\rcommercial importance in the world. This research was carried out in controlled laboratory\rconditions in 2021 to determine the effects of salinity on the germination of flax seeds.\rIn the study, germination rate, root length, root fresh weight, shoot length and shoot fresh weight\rwere evaluated. The result showed that significant differences between different NaCl solutions for\rall evaluated characters. Although the highest value was obtained in the control group in Mures\rvariety, the highest value was obtained in 25 nM NaCl concentration in all other characters except\rfor the germination rate in Dakota variety. The highest germination rate of 93.3% was obtained\rfrom the control application (0 mM NaCl) in both varieties. On the other hand, there was no\rgermination in both varieties in 200 mM application
