Effect of salinity stress on germination indicators of Salvia Officinalis in Astara port

Salvia officinalis is a perennial plant that is utilized in the food industry, cosmetics, and as ornamental flowers in addition to its therapeutic significance. One of the issues limiting the growth and output of many agricultural goods across the world is salinity. The discovery of salinity-resistant medicinal plants is critical due to the growing trend of salty land development and a scarcity of suitable agricultural areas. In 2021, an experiment was conducted on germination indices of Salvia officinalis in Lundville hamlet, 10 km from Astara city, to study the influence of salt stress on Salvia officinalis germination indices using a complete randomized design with three replications. Germination percentage, seed vigor index, radicle length, plumule length, and radicle length to plumule length ratio were all assessed in this research. The results revealed that salt treatments had a considerable impact on germination factors. The 20 mM treatment had the highest percentage of potential germination, with an average of 55.63 percent, which was greater than predicted (47.87 percent). Germination percentage, seed vigor index, radicle length, and plumule length all reduced as salt increased. The relationships between germination percentage and seed vigor (0.905 **), radicle length (0.887 **), and seedling length (0.984 **) were positive and significant, but the ratio of radicle length to seedling exhibited a non-significant negative relationship. According to the findings of this study, Salvia officinalis germination and vegetative growth characteristics were severely decreased when grown under salt stress of more than 80 mM. In summary, the findings revealed that Salvia officinalis is very resistant to saline stress during the germination stage.
