Effect of Salicylic Acid on Photosynthetic Pigments and Chlorophyll Flurescence of Pot Marigold under Salt Stress Conditions
Abstract:   (275 Views)

Salt stress is the second important environmental stress around the world and in Iran. Salicylic acid has been shown to play an important role in stress tolerance of plants. Photosynthetic pigments are responsible for radiation energy absorption and converting to reducing energy and other metabolic processes. In order to investigate the effects of salicylic acid on reducing the detrimental effects of salinity on photosynthetic pigments and chlorophyll flurescence of pot marigold,an experiment was conducted in the research greenhouse of SB University of Kerman as a factorial based on RCBD with 5 replication. Results showed that salt stress decreased flower dry matter, chlorophyll a, chlorophyll b and total chlorophyll content, maximumflurescence, quantum yield, plant height and root length to 22, 7, 91, 35, 30, 31, 40 and 35 percent compare to the control condition. Salt stress increased minimum flurescence to 46 percent compare to the control condition. Application of salicylic acid reduces the detrimental effects of salt stress in all plant characteristics.

Keywords: Salinity, Salicylic acid, Quantum yield, Maximum flurescence, pot marigold.
