Influence of seed priming on emergence and growth of coriander (Coriandrum sativum L.) seedlings grown under salt stress / Vpliv pretretiranja semen koriandra (Coriandrum sativum L.) s solnimi raztopinami na vznik in rast v razmerah solnega stresa

Salinity is one of the biggest limiting factors for agriculture in semi-arid areas of the world. For this reason, an experiment was conducted to study the effect of seed priming with NaCl and CaCl on growth and yield responses of Tunisian coriander cultivar exposed to five levels of salinity (0, 2, 4, 6, 8 g l ). Seeds of coriander were primed with aerated solutions of 0.13 M NaCl and CaCl for 24 h. Results indicated that with increasing salinity, emergence traits (total emergence, mean emergence time), growth parameters (plant height, shoot fresh and dry weight) and mineral contents (K and Ca ) decreased, but to a less degree in primed seeds. In all of the salinity levels, primed seeds possessed higher emergence and growth rate than control. However, further studies are needed to highlight the effect of seed priming on yield and oil content of coriander under salt stress. Slanost je eden izmed največjih omejevalnih dejavnikov kmetijstva v polsušnih območjih sveta. V ta namen je bil izveden poskus za preučevanje učinkov predtretiranja semen z NaCl in CaCl sorte tunizijskega koriandra na parametre rasti in pridelka, ki je bila izpostavljena petim stopnjam slanosti (0, 2, 4, 6, 8 g l ). Semena koriandra so bila tretirana s prezračeno raztopino 0.13 M NaCl in CaCl za 24 h. Izsledki so pokazali, da so z naraščajočo slanostjo parametri vznika (totalni vznik, poprečni čas vznika), rasti (višina rastlin, sveža in suha masa poganjkov) in vsebnosti hranil (K in Ca2 ) upadli, vendar manj pri predhodno tretiranih semenih. Predhodno tretirana semena so imela pri vseh stopnjah slanosti boljši vznik in večjo rast kot kontrola. Za preučitev učinka predtretiranja s solmi na pridelek in vsebnost olj koriandra v razmerah solnega stresa so potrebne še nadaljne raziskave.
