Abstract

TUCUCH-HAAS, César J. et al. Salicylic acid increases the accumulation of macro and micronutrients in habanero pepper. Rev. Mex. Cienc. Agríc [online]. 2019, vol.10, n.4, pp.839-847.  Epub May 22, 2020. ISSN 2007-0934.  https://doi.org/10.29312/remexca.v10i4.1694.

The results of the effect of salicylic acid (AS) on the nutritional absorption of Capsicum chinense are presented. 1 μM of AS was sprayed on the canopy of habanero pepper seedlings and distilled water as control. The results obtained show that aspersions of 1μM of salicylic acid (SA) significantly increase the length, weight, weight and dry weight of roots, stems, leaves and fruits of this species, as well as the levels of nitrogen (N), phosphorus (P) ) and potassium (K) in the different organs of the plants at the time of harvest. The accumulation of N, P and K was higher in fruits (116, 110 and 97%), leaves (45.5, 39.4 and 29.1%), root (52.6, 17.0 and 29.4%) and in stem (5, 39.4 and 28.3%) on the values of the control plant. The levels of copper, zinc, manganese, iron, boron, calcium and magnesium were also increased in most tissues by the effect of AS. It is proposed that the positive effect of the AS of increasing the size of the roots favors the absorption and accumulation of macro and micronutrients in the tissues of the plant.
