Abstract:\u00a0<\/strong><\/span><\/p>\n

The research aimed to evaluate the most important productive and phenological characteristics of R. damascena<\/em>, and R. centifolia<\/em>. Cultivated in Lattakia conditions at two different altitudes (650 and 10000m) during 2020-2022. The results showed a variation in the productive and phenological characteristics between the phenotypes of the two species on the one hand and the two sites of the experiment on the other hand. The best results were in site B (1000) m, which gave the highest value for the average plant production and the number of flowers on the plant (66.4), and the average plant productivity (366.06) g\/plant. It also achieved the highest value for the flowers content of essential oil. As for the phenotypes as R. centifolia<\/em> was superior to the average flower weight (12)g and average productivity of (407.5) g\/plant, but it contained the least number of flowers and the lowest percentage of essential oil. The results of the qualitative analysis of the essential oil resulting from the two studied species showed that it contained good proportions of many important compounds (Nerol, Geraniol, , Linalool, Tetracanol, Nondecane) and\u00a0 R. centifolia<\/em> is superior in its essential oil content to the Nerol compound compared to R. damascena<\/em>. The results of the study of phenological phases showed a delay in the phenological phases of the studied phenotypes with increasing altitude above sea level.\u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0\u00a0<\/span><\/p>\n
