Abstract

Water stress is one of the most important abiotic stresses limiting growth and plant yield under dryland conditions, which affects the morphological and physiological characteristics of plants. To evaluate morphological characteristics, yield, mucilage, and seed oil of Lallemantia iberica (M.B.) Fisch. & C.A. Mey. ecotypes [Kerman (Kerman province), Naein (Isfahan province), Sanandaj (Kurdistan province), Mashhad (Razavi-Khorasan province), and Malekan (East-Azerbaijan province)] under dryland conditions, an experiment was conducted as a randomized complete block design with three replications in the medicinal plants research farm of Yasouj Agricultural Research Center and Natural Resources in the 2016-2017 crop year. The results showed that ecotype significantly affected morphological traits, seed yield, mucilage yield, and oil yield. The highest seed yield was obtained from Kurdistan (529 kg ha-1) and Mashhad (515 kg ha-1) ecotypes. The highest and lowest oil yield was related to Kurdistan (211 kg ha-1) and Kerman (189 kg ha-1) ecotypes, respectively. Mashhad (22.7 kg ha-1) and Malekan (18.2 kg ha-1) ecotypes had the highest and lowest seed mucilage yield, respectively. Although there was no significant difference between the oil and seed mucilage percentage of the ecotypes, the highest (41.3%) and lowest (39.9%) oil content was found in Kerman and Kurdistan ecotypes and the highest (4.4%) and lowest (3.7%) mucilage percentage belonged to Mashhad and Kurdistan ones, respectively. Overall, the results showed that Kurdistan and Mashhad ecotypes are suitable for cultivation under dryland conditions of Yasouj due to higher yield of seeds, mucilage, and seed oil.
