Abstract
Se evaluaron extractos de la fracción aérea y radicular de Ulex europaeus L., obtenidos mediante extracción acuosa y metanólica aplicados a plántulas de ají (Capsicum annuum L.) en condiciones de laboratorio. Los tratamientos fueron seis dosis (0, 20, 40, 80, 160 y 320 mg kg¹) de raíz acuoso (Ra), raíz metanólico (Rm), parte aérea acuoso (Ha) y parte aérea metanólico (Hm), y como testigos cafeína (C) y agua destilada (A), con seis repeticiones. Su efecto se evaluó en la producción de materia verde (MV) y en materia seca (MS) de plántulas de C. annuum. El extracto Ra obtuvo el valor más alto en producción de MS (g), mientras que en contenido de MV (g) ambos extractos presentaron mayor rendimiento que el testigo. Por otro lado, las dosis más altas del extracto Ra obtuvieron los mejores resultados en MV y en MS. Todas las dosis presentaron mejores resultados que el testigo; en tanto Rm concentró los valores más altos de producción en dosis bajas. En cuanto a los extractos de parte aérea se observó que ambos tuvieron efectos sobre la producción de MV y MS, siendo significativamente mayor al testigo. En cuanto a las dosis, 80 y 160 mg kg¹ obtuvieron los mejores resultados en MV. En dosis altas del extracto Hm se observó un incremento de la MV respecto al testigo, no así de la MS. Finalmente, es posible afirmar que es factible utilizar extractos de U. europaeus para incrementar la producción de MV y MS en C. annuum.
Under laboratory conditions, aerial and root extracts of Ulex europaeus L., obtained by methanol and aqueous extraction, used in chili pepper (Capsicum annuum L. cv) seedlings, were assessed. The treatments used were 6 doses (0, 20, 40, 80, 160 and 320 mg kg–1) of each type of extract: aqueous root (Ra), methanol root (Rm), aqueous aerial (Ha) and methanol aerial (Hm), and caffeine (C) and distilled water (A) as controls; with 6 replications. The effect of the extracts on the production of green matter (GM) and dry matter (DM) of C. annuum seedlings was assessed. The Ra extract obtained the highest rate in DM production (g), while in GM content (g) both extracts showed a higher yield compared to control. On the other hand, the highest Ra extract doses obtained the best results in GM and DM. All doses showed better results than controls; Rm showed the highest yield rates with the lowest doses. Regarding aerial extracts, it was observed that both had effects on GM and DM production, being significant higher than controls. 80 and 160 mg kg¹ doses showed the best results in GM. In high doses of Hm extract, an increase in GM was observed compared to control; but in DM, it was not. Therefore, feasibility of using U. europaeus extracts to increase GM and DM production in C. annuum can be ensured
