چکیده مقاله:

This study was carried out to evaluate drought stress tolerance in Thymus kotschyanus accessions using a factorial experiment based on a Completely Randomized Design (CRD) with 5 replications during 2013-2014 in Qom, Iran. The first factor was the accession with 17 levels and the second factor was drought stress with three levels of irrigation including 80% (control), 60% and 40% Field Capacity (FC). Data were collected for shoot length, root length, root to shoot length ratio (R/S), shoot fresh yield, oil percent, oil production and Relative Water Content (RWC). Result of analysis of variance showed significant differences between accessions, irrigation and accessions by irrigation interaction for all of traits (p
