| Abstract | ||
| To study the effect of different levels of salicylic acid in Zea mays L. photosynthetic pigments under salt stress , a factorial experiment based on a Randomized Complete Block Design with three replicates was used . Treatments consisted of three salinity levels (0.5, 5.0 and 9.5 dS m-1) and five salicylic acid concentrations ( 0,250,500,1000 and 1500) µM.L-1 SA . Chlorophyll a, chlorophyll b and Carotene concentration in leaves were measured . The results showed that salt stress caused a significant decrease in photosynthetic pigments concentrations (chlorophyll a, chlorophyll b, and carotene) . Foliar application of salicylic acid caused a significant increase in chlorophyll a, chlorophyll b and carotene concentrations , especially under salt stress. | ||
