Resumen: Applications of low concentrations salicylic acid (SA) to the shoots of seedlings of horticultural plants such as habanero pepper (Capsicum chinense ) or to perennial trees such as the Ramon (Brosimun alicastrum) significantly increase their growth, development and producttivity.In chile pepper it was found that the positive effect of SA on root growth is correlated with an increased uptake of macronutrients and micronutrients which are allocated in the plant tissues. Data have shown that plant tissues treated with SA had significantly higher levels of macronutrients. Accumulation of nitrogen, phosphorus and potssum was higher in fruits (116%, 110% and 97%), leaves (45.5%, 39.4% and 29.1%), roots (52.6%, 17% and 29.4%), and stems (5.0%, 39.4% and 28.3%) with respect to the control plants. The levels of other nutrients, such as copper, zinc, manganese, boron, calcium, manganesium and iron, were also higher.The application of 1 micromolar SA to shoots of trees, affected the root length. The control plants had 42 cm, and those of the treated plants 65.5 cm, equivalent to an increase of 55.7%. Fresh weight of the root was 158.3% higher in the treated plants and the dry weight increased by 160.7%. Increases were also observed in stem length (46%), stem diameter (25.9%), fresh weight (78.3%), and dry weight (89%), in comparison with the control. The number of leaves presented in treated plants averaged 12.6, whereas the control plants showed an average of 9 leaves with a lower leaf area.
