Abstract

Salicylic acid (SA) or orthohydroxybenzoic acid and related compounds which are belong to this group are plant phenolics that play a major role in regulation of many physiological processes e. g. growth, development, ion absorption and seed germination. The effect of SA on germination, shoot and root fresh and dry weights , shoot and root length, leaf area, sugar and protein content were investigated of pepper (Capsicum annuum L.) under UV-A, UV-B and UV-C radiation. The plants were grown in vermiculite. Before applying the treatments, plants were subjected to a based nutrient solution (Long Ashton) for 5 weeks. After 5 week, leaves of plants were sprayed with 1.5 mM SALICYLIC ACID and plants were treated under treatment UV-A, UV-B and UV-C for 2 week. Results showed that the percentage of seed germination significantly increased under UV-A and UV-C with SALICYLIC ACID. Rate of germination significantly decreased under UV-C and SALICYLIC ACID. In addition decreased leaf area in the UV-applied group was restored by SA application. Shoot and root fresh and dry weights significantly increased under UV-A, UV-B and UV-C with SA in comparison with only UV-A, UV-B and UV-c. UV-A, UV-B and UV-C stress and SALICYLIC ACID treatment increased stem length but only UV-B and UV-C stress and SALICYLIC ACID treatment increased root length. Therefore we concluded that the application of SALICYLIC ACID can protect plants against UV-radiation and in terms of improving the measured plant growth criteria. Sugar content significantly increased under UV-A, UV-B and UV-C when SALICYLIC ACID was applied. Protein content significantly increased under UV-A when SALICYLIC ACID were applied.
