The effects of different levels of salinity (NaCl) and temperatures on seed germination parameters of anise

In many studies, the properties of the drug and the impact of anise on the body's mechanisms of activity have been proven. . Salinity stress is a non-living stress that has adverse effects on seed germination. In order to study the effect of temperature on germination of anis under salinity stress, a factorial with six temperature levels (5, 10, 15, 20, 25, 30) in terms of temperature and seven levels of salinity (0, 2, 4-, 6-, 8-, 10-, 12-bar) of sodium chloride. The results of the experiment showed that germination percentage, germination rate, time to 50% germination and time to 90% germination were significantly affected by salinity, temperature and their interaction. Increasing salinity levels significantly reduced all studied traits. At a temperature below 10 ° C (5 ° C), germination percentage was significantly lower. Regarding the problem of salinity in regions where the temperature problem is high, based on the results, it was found that the seeds of the anise are susceptible to salinity and heat.
