Sažetak
In this study, the influence of caproic acid seed pretreatment on the resistance of linseed (Linum usitatissimum L.) seedlings under drought stress conditions was investigated. Seed pretreatment was performed by soaking the seeds in water, 0.5 mM and 1.0 mM caproic acid solutions for 30 minutes, while to induce drought stress (treatment) the seeds were germinated for 7 days on a medium with solutions of polyethylene glycol with osmotic potential -0.17 and -0.53 MPa (PEG 10 % and PEG 20 % ), after which seed germination, seedling weight, radicle length, hypocotyl and seedling length were measured. The study showed that pretreatment of linseed with caproic acid had a significant effect (p <0.05) on radicle length and seedling length. Under conditions of less drought stress (PEG 10 %), pretreatment of seeds with 10 mM caproic acid solution showed the greatest positive effect on hypocotyl, radicle and seedling length. The results of this study indicate that caproic acid could be used for the pretreatment of linseed seeds to improve the early growth and development of seedlings under drought stress conditions.
