Salicylic Acid µM
Fig. 3 Effect of different concentrations of Salicylic Acid on tomato plantlets (Lycopersicon
esculentum cv. Maya), 20 days after emergence. Values with the same letter within columns are
equal according to the Tukey test (P B 0.05). Each value is the mean of 24 replicates ± standard error

3 Impact of Salicylic Acid on Productivity of Plants
of Economic Importance
To analyze the potential benefits of SA to enhance food production an extended
series of experiments were conducted (1) with different plant species of interest for
food production, (2) in different agro-ecosystems; taking into account climatic
conditions of soil, temperature, humidity and the quality of water for irrigation,
