RAMIREZ RODRIGUEZ, Silvia C. et al. Chitosan nanoparticles improve the nutraceutical quality of triticale sprouts. Rev. Mex. Cienc. Agríc [online]. 2021, vol.12, n.4, pp.579-589.  Epub Feb 21, 2022. ISSN 2007-0934.  https://doi.org/10.29312/remexca.v12i4.2929.

The use of chitosan nanoparticles (NPs CS) has become a promising alternative in modern agriculture as an inducer in the biosynthesis of secondary metabolites. The objective of this research was to evaluate the effect of NPs CS on the nutraceutical quality of triticale sprouts (x Triticosecale Wittmack). Increasing doses of NPs Cs: 0, 0.1, 0.2, 0.4 and 0.8 mg ml-1 were applied only once at the imbibition stage, then they were left in Petri dishes for 7 days at 25 ±2 °C temperature. NPs CS did not affect germination or fresh root weight at the tested concentrations, and the concentration of 0.1 mg ml-1 increased the fresh weight of the shoots up to 83.3%. In the presence of 0.8 mg ml-1 of NPs CS phenolic compounds decrease by 7% and flavonoids increase by 29%. The results confirm a promoter effect of NPS CS on sprouts, opening the possibility of being used as inducers in the biosynthesis of bioactive compounds in triticale sprouts.
