Effect of salicylic acid on photosynthetic pigments of Myrtus communis L. under salt stress condition
Journal Title: Journal of Biodiversity and Environmental Sciences (JBES) - Year 2017, Vol 11, Issue 6
Abstract
Salicylic acid is known as an important signaling molecule that regulates plant reactions to salt stresses. It plays a critical role in the regulation of physiological functions as non-enzymatic antioxidant. In this study we investigated the effects of different concentrations of salicylic acid (0, 50, 100 and 150 ppm) that were sprayed on one age seedlings of myrtle (Myrtus communis L.) with different levels of NaCl (0, 25, 50, and 100 mM) on activities of total chlorophylls, chlorophyll a, chlorophyll b and Carotenoid. Total chlorophylls showed the most significant decrease at 100 mM of salinity concentration and salicylic acid treatments was significant decrease at 100 and 150 ppm concentrations in all treatments. Chlorophyll a had the highest content in 25 Mm and was the least content at 100 Mm of salinity treatment. There was not a significant differences in chlorophyll b content between different levels of salinity applied. But showed significant decrease in 150 ppm salicylic acid concentration. Carotenoid content had a significant increase in 100 Mm of salinity but had not in salicylic acid treatment. Total chlorophylls and chlorophyll a had the highest decrease and significant interactions in 100 mM of salinity with 150 ppm salicylic acid concentration.
