QUESADA, Patricia  e  LORIA, Carlos Luis. Notes on management of lychee trees (Litchi chinensis) and its relation to flower induction. Agron. Costarricense [online]. 2016, vol.40, n.1, pp.75-80. ISSN 0377-9424.

Observations were made in the Fabio Baudrit Experiment Station. Several chemical and cultural management practices were applied, over the course of several years (2008-2012), on young lychee trees that had been propagated by means of air layering, with the purpose of observing their influence on blooming. The practices and products tested were: irrigation restriction, branch thinning, potassium nitrate, pachlobutrazole and ethrel. None of the management practices applied had a positive effect on the flowering of the trees under observation. It is speculated that lychee trees require prolonged periods with temperatures under 20ºC, for flower induction to occur.
