Abstract | ||||
This study was carried out during two successive seasons of 2019 and 2020 in an open field condition at a private farm in EL-Behira governorate, Egypt. This work aim to study the effect of spraying chitosan with different concentrations (0.0, 1, 2 and 3 g L-1) on plant growth, chemical components, essential oil yield, photosynthetic pigments, total flavonoids, total amino acids, total phenols and total carbohydrates of lavender plants. The Experimental layout was randomized complete blocks design (RCBD) with 3 replicates. The obtained results showed that using chitosan concentration of 3g L-1 significantly increased plant height, number of branches plant-1, fresh and dry weights of plants, volatile oil percentage and volatile oil yield per plant as well as chemical constituents such as Linalool and 1, 8cineol. It also increased chlorophyll content, total amino acids and total carbohydrates. While chitosan treatment at 2 g L-1 gave the maximum mean values of total carotenoids, total flavonoids and total phenols compared to control and the other chitosan levels under this study conditions. | ||||
