ARIZA FLORES, Rafael et al. Phytohormones and bio-stimulants to flowering, production and quality of Mexican lime in winter. Rev. Mex. Cienc. Agríc [online]. 2015, vol.6, n.7, pp.1653-1666. ISSN 2007-0934.

Mexican lime production Citrus aurantifolia (Christm) Swingle is low during the months of December to April and cause an increased demand and high profitability of the crop. The study consisted to induce flowering through the application of plant hormones and bio-stimulants to obtain production and quality of Mexican lime in winter. The effects in inducing flowering occurred 30 days after the application of urea was made inAugust, meanwhile presented flowering at 45 days with Biofol, glutamic acid, urea and control and induced October, November and the first half of December in trees, while it was slightly moderate with gibberellic acid and low in the control (without application). Production yields were 9 763 kg ha^-1 with Biofol, declining to 80, 70 and 65% with glutamic acid, control and urea, same that were moderately lower with gibberellic acid, naphthalene acetic acid, paclobutrazol and thidiazuron and very low with 2-chloroethylphosphonic acid and control intact. The fruits acquired a higher quality in weight, diameter, color index, percentage of juice, titratable acidity, firmness and maturity index with Biofol, glutamic acid and urea. Biofol, glutamic acid and urea as bio-stimulants timely induce flowering and fruiting of Mexican lime in winter, favoring fruit quality and sustainability of the crop.
