TIGHE-NEIRA, Ricardo et al. Effect of extracts of Ulex europaeus L. on the biomass production in chili pepper (Capsicum annuum L.) seedlings, under laboratory conditions. Idesia [online]. 2016, vol.34, n.5, pp.19-25.  Epub Sep 07, 2016. ISSN 0718-3429.

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 kg' doses showed the best results in GM. In high doses ofHm 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.
