Plant regulators on vegetative growth of Tommy Atkins and Kent mangoes.

The present paper has the purpose to evaluate the effect of plant growth regulators in the management of vegetative budding on mango Tommy Atkins' and Kent. Three plant growth regulators, sprayed to the leaves were evaluated: prohexadione-Ca, ethyl-trinexapac and chIormequat chloride, applied in two doses, and compared to paclobutrazol applied to the soil, using a randomized block design, with four replications and two plants per plot. In order to compare the effects of the treatment, data were recorded to vegetative growth (number and lenght of the shoots). Futhermore the levels of gibberellins in the apical area of the shoots of Tommy Atkins cultivar were quantifified, from the experiments set up until the beginning of floral induction
