Citrus, new inducers, biostimulants, phytohormones.
Objective: To evaluate new hormonal and biostimulant products to induce flowering of Mexican lime (Citrus aurantifolia Swingle) for winter production at the state of Guerrero, Mexico.
Design/methodology/approach: Prohexadione calcium (PHD-Ca), cytokinins, paclobutrazol, biuretic urea, granulated urea (46%) and a control were evaluated.
Results: There are differences between treatments for the number of flowers and number of fruits (Pr>0.0411 and 0.048); regard the “number of flowers” variable, paclobutrazol, prohexadione calcium and granulated urea (46%) stood out; while, prohexadione calcium, paclobutrazol and cytokinins favor the “number of fruits” variable. The yields show statistical differences (Pr>0.0332) and the cytokinins and paclobutrazol stood out.
Findings/conclusions: The usage of cytokinins for induction and winter production of Mexican lime is suggested.
