Abstract:
This study was conducted to evaluate the effects of foliar spraying with salicylic acid on vegetative growth of safflower under saline conditions in Damsarkho village, Latakia, Syria in 2023. A factorial trial based on a randomized complete design (R.C.D.) with three replications was used. The treatments consisted of four salinity levels (0, 4, 8 and 12 ml/cm2) and four salicylic acid concentrations (0, 0.5, 1 and 1.5 mmol). Traits such as plant height, number of branches, leaf content of chlorophyll, proline, MDA and number of seeds per plant were measured. The results of the study showed that salinity levels and salicylate concentrations significantly affected (P<0.05) the studied properties and indicators, and as salinity increased, the properties of all studied indicators decreased. Comparisons of averages indicated an improvement in the vegetative growth Characteristics, biochemical indicators, and studied plant productivity when treated with salicylic acid, especially at a concentration of 1 mmol. The interaction between salinity and salicylic acid led to significant effects on the studied indicators. Low concentrations led to a relative improvement in the studied morphological, biochemical and production characteristics, and the A2S1 treatment outperformed all treatments and the control. In contrast, the high concentration led to negative effects.
Keywords: salicylic acid, salt stress, safflower.
