Cross-talk between nitric oxide, hydrogen peroxide and calcium in salt-stressed Chenopodium quinoa Willd. At seed germination stage

Popis výsledku v původním jazyce

Seed germination is critical for successful crop production and this growth stage can be very sensitive to salt stress depending on the plants tolerance mechanisms. The pretreatment of Chenopodium quinoa seeds with CaCl2, H2O2 and sodium nitroprusside limited the adverse effect of salt stress on seed germination. The pre-treated seeds showed a significant increase in germination rate, relative germination rate and germination index while the mean germination time was significantly reduced under both optimal and stress conditions. In parallel with seed germination, the negative effect of salt stress on the activity of alpha-amylase and beta-amylase was reduced in pre-treated seeds. The amylase enzymes are responsible for starch hydrolysis, so the reduction of amylase activity by salt stress resulted in higher starch content in the seeds and lower concentrations of water-soluble sugars such as glucose. Pretreatment stimulated amylase activity resulting in starch breakdown and increased content of water
