Potential Benefits of Salicylic Acid in Food Production R. Martín-Mex, A. Nexticapan-Garcez and A. Larqué-Saavedra
Abstract Plant species of Angiosperms and Gymnosperms applied with Salicylic acid respond in a positive manner when root system, flowering, stress or productivity is measured. Moreover, the published work indicates that Salicylic Acid application to plants of economic importance might be a good material to use it more widely to increase food production. The advantages to test this molecule is that (a) is a natural and eco-friendly product, (b) nanoquantities are required to produce positive effects, (c) is easy to be applied, and (d) is a cheap chemical available, almost anywhere.

1 Introduction One of the objectives for this millennium, announced by the United Nations, is the global elimination of food poverty. This goal is undoubtedly far from being accomplished, as many developing countries have been unable to establish their policies for food security, which means that the strategies implemented by each country, along with the global strategies being carried out, must be carefully observed. It is a well known fact that three permanent sources have been recognized as factors to improve food production. These are: biotechnology in its widest context, vegetable nutrition and biodiversity. It is in this context the purpose of this chapter is to present evidences that Salicylic Acid (SA) on its own could be consider as a chemical with the potential to enhance food production as is illustrated in the following diagram.

2 Physiological Studies of Exogenous Application of Salicylic Acid as a Basis to Increase Plant Productivity (a) Positive Effect of Salicylic Acid in Stress Physiology From the early 1970s, ongoing research and development has been carried out from which four basic contributions can be highlighted to support the premise that SA has potential in food production. The first refers to 1978 when it was proposed that the application of aspirin to bean plantlets had an effect on the hydric status of the plant, a fact that was confirmed in specific bioassays carried out with stomata using the bioassay of Commelina communis epidermis strips (Larqué-Saavedra 1978, 1979). The news was given coverage by the international press, whose reports indicated that aspirin could be used to save crops in conditions of stress caused by drought (The Times 1978). This indication, to the effect that salicylates had the potential to participate in the physiology of plants subjected to stress, was later demonstrated by several authors th
