Abstract

For the investigation of effects of nano Zinc chelate foliar application on drought stress resistance of Dracocephalum kotschyi, and it's qualitative and quantitative characteristics, a field experiment, was conducted during 2016 growing season at research field of Imam Khomeini International University of Qazvin, Iran. The experiment was laid out in Factorial experiment based on randomized complete block design with 6 treatments and 3 replications. The experimental factors were; drought stress at three levels (100, 60 and 30% of field capacity) and nano zinc chelate at two levels (with and without foliar application). Results showed that with increasing of drought stress intensity, fresh and dry weight of plants as well as plant height were significantly decreased, but foliar application of zinc caused increasing in these traits. The maximum essential oil percentage (1. 53%) was observed in plants treated with moderate drought stress and Zn foliar application. Zinc application could increase the amount of chlorophyll a, however the highest Chlorophyll content (0. 85 mg/gFW) was obtained by 100% FC irrigation. Main constituents of D. kotschyi essential oil are Limonene, verbenone, neral and citral. The maximum percentage of Limonene (30. 72%), verbenone (33. 72%) and neral (7. 37%) were found in plants that treated with medium drought stress (60% FC). However the amounts of Limonene, neral and verbenone were increased in presence of zinc foliar application.
