Abstract


The Rosa damascena Mill. is cultivated in different parts of Iran. For evaluation of its essence, the experiment was carried out on 50 accessions during 2014-17 using randomized complete blocks design with three replications. Results showed that the essence of Kermanshah11 (0.412 g), Yazd 1 (0.400 g), Isfahan 4 (0.364 g), Lorestan 1 (0.361 g), Kermanshah 2 (0.350 g) and Isfahan 3 (0.331 g) accessions had a higher amount of essence. Strong positive correlation coefficients (p≤0.01) were found between essence of citronellol- n-eicosan (0.845), citronellol- n-heneicosane (0.879), n-nonadecane-geraniol (0.883), n-heneicosane-geraniol (0.842), n-heneicosane- geraniol (0.850), n-eicosane- geraniol (0.885), n-nonadecane- geraniol (0.930). Comparing the years, the accessions of Isfahan 5, Arak 1, Kordestan 1, West Azarbaijan 1, Tehran 1, Arak1, Fars 1 and Zanjan1 had the highest citronellol, geraniol, geraniol, n-tetradecanal, n-nonadecane, n-eicosane, n-pentacosane, n-heneicosane, respectively.
