Abstract

The purpose of this experiment was to investigate the effect of deficit irrigation and chitosan on some physiological traits of Mentha spicata L. This experiment was conducted in a completely randomized block design in a split plot arrangement with three replications in University of Zanjan. The experimental treatments were irrigation at two levels (100% and 60% field capacity) as the main factor and chitosan treatment at three levels (0, 50 and 100 mg/l) was considered as a sub factor. The results showed that spraying with chitosan increased chlorophyll content. The highest chlorophyll content (1. 240 mg gr-1 f. w) was obtained at 100 mg/l chitosan under complete irrigation conditions (100% field capacity). The spraying application of 100 mg/l chitosan and deficit irrigation conditions (60% field capacity) caused the highest amount of carotenoids (0. 45 mg gr-1 f. w), phenol (9. 989 mg gr-1 f. w), flavonoid (6. 993 mg gr-1 f. w) and proline (23. 96 mol gr-1 fw). The highest level of Antioxidant activity (91. 16%) was observed in 50 mg/l chitosan under deficit irrigation. Also, deficit irrigation and chitosan had a positive effect on the essential oil yield, so that the highest essential oil yield (10. 44 kg/h) was obtained at 100 mg/l chitosan concentration and under deficit irrigation conditions. Overall, the results showed that chitosan treatment had positive effects on drought stress and non-stress conditions and improved the negative effects of drought stress.
