Effect of Acetyl Salicylic Acid (Aspirin) on Growth and Yield of Faba Bean (vicia faba l.) under Salinity Stress

Abstract

Salinity stress is considered one of the major abiotic stress factors, which strongly reduces crop productivity. Acetyl salicylic acid (common aspirin) which plays an important role as plant hormones, may be used to prevent or lessen crop losses under stress condition. The present study aimed to evaluate the effect of Aspirin in alleviating the negative effects of salinity stress for faba beans (vicia faba l.). For this purpose, pots experiment was conducted involving faba bean plants. The plants were subjected to 0, and 100 mM NaCl and also treated with and without aspirin solution (75mg/L). plants were grown under semi-controlled environment in randomized complete design (RCD) with four replicates. After two months of sowing, faba bean plants were treated with salinity (100mM NaCl) and foliar sprayed with aspirin solution (75mg/L), growth and yield responses were measure at harvest. The obtained results showed that irrigation with saline water negatively affected the growth and yield parameters of faba bean (P < 0.0001). However, the application of aspirin to NaCl stressed plants displayed enhancement of growth and yield traits of faba beans (P < 0.0001), which indicated by increasing plant height and number of branches plant-1. Number of pods plant -1 and seed yield plant-1. In conclusion, aspirin applicattion alleviated the negative effects of NaCl toxicity in faba bean plants. However, further research is needed to validate the aspirin doses at user level.
