Effect of Baraceinolide and Sodium Chloride on the Proportion of some Volatile Oils and Proline in majorana Leaves

Abstract

This research was carried out in collage of Agriculture, Kirkuk University in season 2022, to study the effect of bracinolide and sodium chloride in proportion of aviator oil and proline in leaves Marjoram plant. The experiment designed by t two factors. fires factor baraceanolide (0, 0.1, 0.2, 0.3) g. L-1 while second factor sodium chloride (0, 5, 10, 15) g. L-1. Using (R.C.B.D) and according Duncan's under probability 5%. Each experimental unit includes three pots, one sector contains sixteen experimental units, and the experiment consists of three sectors. Results showed positive effects as a result of using a growth regulator, that spraying   0.2g. L-1 baraceanolid gave the highest number of leaves 510.21, while concentration at 0.3 g. L-1 recorded the highest in nitrogen reached 2.52%, percentage of volatile oil carvone at 55.47%, Limonene at 14.96% and Linalool 6.48%, as well proline reached 26.91 at concentration of 15 g. L-1 salts.
