Resumen

HECHEVARRIA SOSA, Isabel; RODRIGUEZ GONZALEZ, Horacio  y  MEDEROS MEDEROS, Dagoberto. Efectos alelopáticos de Aloe vera (L.) N. L Burm. sobre otras especies de plantas medicinales en condiciones de laboratorio. Rev Cubana Plant Med [online]. 2003, vol.8, n.2. ISSN 1028-4796.

Allelopathic effects of Aloe vera (L) N.L Burm on other species of medicinal plants under laboratory conditions The allelopathic association among 7 species of Cuban medicinal plants and Aloe vera L.N. Burm was studied under laboratory conditions. The interest was centered on the influence of residues of Aloe and an aqueous extract of a gel 20 % of the same plant on the growth of medicinal species. The studied species were: Calendula officinalis L., Plantago lanceolata L., Plantago major L., Matricaria recutita L., Ocimum gratissimum L., Ocimum basilicum L. and Ocimum tenuiflorum L Seven experiments were made, one per species. Every experiment was repeated 4 times and in all cases the length of the epicotyl and of the hypocotyl measured in cm and the corresponding dry mass measured in grams, obtained from the seeds of the associated plants and not from Aloe, were compared. A simple variance analysis was carried out and the means of the indicators were compared with Turkey's test, with a significance of 1 %. Four species, Calendula officinalis L., Plantago lanceolata L., Matricaria recutita L. and Ocimum tenuiflorum L., had a limited growth in the epicotyl and hypocotyl, or in one of these two elements when they were associated with A. Vera. In the epicotyl of P. lanceolata L. and in the hypocotyl of C. Officinalis L., the greatest accumulations of dry mass were observed with the lowest growths. It is recommended to take into account the results obtained for field studies with the analyzed species.
