In order to evaluate the biochemical properties of dragon’s head (Lallemantia iberica L.) ecotypes’ using some anti-perspirants in rainfed conditions in the crop year 2018, an experiment has been conducted in Karaj and Khorramabad regions. The experiment is based on a randomized complete block design (RCBD) with a factorial arrangement, consisted of three replications. The first factor involves four different ecotypes of dragon’s head (Kurdistan, Takab, Nazarkahrizi, and Kalibar) and the second factor includes three anti-transpirant compounds (kaolin with a concentration of 5%, chitosan with a concentration of 1%, and Ista with a concentration of 2%) as well as no anti-transpirant (control). The results show that using anti-transpirants has increased the amount of the activity of catalase and peroxidase enzymes. Ista anti-transpirant has had a greater effect on enzyme activity than kaolin and chitosan. The highest amount of peroxidase and catalase (0.51-0.39 unit mg/protein) are obtained from the ecotypes of Kurdistan treated with Ista and Karaj cultivation, respectively. In addition, the highest grain yield and biomass yield are obtained from treatment with chitosan, which has increased by 4% to 20%, compared to the control, respectively. Based on the results, using anti-transpirants in dryland cultivation conditions improves most of the studied yield traits and biochemical traits compared to the control.

This study was carried out to assess yield, yield components and quality traits of dragon’s head (Lallemantia iberica L.) ecotypes’ seeds grown using some anti-transpirant agents in rainfed system in two regions of Iran including Karaj & Khorramabad in 2018. The experiment was performed based on a randomized complete block design (RCBD) with a 4×3 factorial arrangement consisting of three replications. The first factor consists of four different ecotypes of dragon’s head (Kurdistan, Takab, Nazarkahrizi and Kalibar) and the second factor including three anti-transpirant compounds (kaolin with a concentration of 5 Percent, chitosan with a concentration of 1 Percent and Ista with a concentration of 2 Percent) and no anti-transpirant (control). The results indicated that the triple interaction of ecotypes, anti-transpirant and location on most of the studied traits was significant. Among anti-transpirant, chitosan had the greatest effect on cultivated ecotype & increased grain, biomass, oil and mucilage yields by 20, 4, 11, and 18 Percent, respectively. Also, Nazarkahrizi, Kalibar, Kurdistan and Takab ecotypes cultivated in Karaj had the highest values in the studied traits under foliar application with anti-transpirant, respectively. According to the studies conducted in this study, the selection of a suitable ecotypes with the region and the use of antiperspirants improve the yield & yield components, quality traits of dragon’s head in rainfed cultivation conditions.
