The effect of ascorbic acid and salicylic acid foliar application on growth indices and enzymatic activity of savory(Satureja hortensis L.)

A study to evaluation the effect of ascorbic acid and salicylic acid on growth indices and enzymatic activity of savory (Satureja hortensis L.) that Which is one of the useful medicinal plants and spices of the mint family, in a completely random statistical design with 7 treatments, 3 replication and each replication with 3 plant, a total of 63 plants, were done. Ascorbic acid and salicylic acid spraying each with 3 concentrations 50, 75 and 100 mg/l from the 4 to 6 leaf stage for three consecutive weeks and twice a week, were done. Distilat water sues as a control. Growth indices such as root and air fresh and dry weight, total chlorophyll content and catalaz, superoxide dismutase and peroxidase enzymes activity, were evaluated one week after the last spraying step. The results showed that the highest air fresh and dry weight, root dry weight, total chlorophyll content and proxidase enzymes activity in salicylic acid 100 mg/l treatment and the highest root fresh weight, catalaz, superoxide dismutase enzymes activity in ascorbic acid 100 mg/l treatment, were obtained. Therefore, according to the research results can be expressed that foliar application with different concentrations of ascorbic acid and salicylic acid improved the growth indices and enzymatic activity of savory (Satureja hortensis L.).
