CASTRO, Paulo R. C. et al. Effects of triacontanol on germination of maize and tomato seeds. An. Esc. Super. Agric. Luiz de Queiroz [online]. 1987, vol.44, n.2, pp.891-899. ISSN 0071-1276.

This study was carried out to determine the effects of triacontanol 0.01 mg.1-1, 0.1mg .1-1 and 1 mg.1-1 on germination of Zea mays cv. Cargill-525 and Lycopersicon esculentum cv. Kada seeds, under laboratory conditions. Measurements realized 7 and 14 days after sowing in Petri dishes with 10 ml of chemicals solution, showed that higher triacontanol concentrations presented a tendency of increased radicle and hypocotyl growth of tomato seedlings, 14 days after application. At this time it was verified that higher triacontanol concentrations showed a tendency of increased hypocotyl growth of maize seedlings.
