Mixture of florasulam + 2,4-D + Kelpak applied at the dose 3.75g a.i x [ha.sup.-1] + 180g a.i x [ha.sup.-1] + 2[dm.sup.3] x [ha.sup.-1] at the growth stage BBCH 30;
Two sequential applications of 2,4-D, each one with 1,000 g [ha.sup.-1] of the acid equivalent (a.e.) resulted in better control of glyphosate-resistant cotton stalk regrowth in the three environments studied (Table 4).
This way, the objective of this work was to evaluate the agronomic characteristics of pumpkin fruits of Tetsukabuto hybrid as a function of 2,4-D doses as phytohormonal inducer.
Considering these three aspects, the media showing these three desired characteristics were those containing the 2,4-D growth regulator at concentrations of 6.7 [micro]mol [L.sup.-1] and 9.0 [micro]mol [L.sup.-1] in association with BAP at these concentrations (M11, M12, M15 and M16).
2,4-D, NAA in combinations with BAP (ranging from 0.5 to 2 mg L- 1) such as 0.5 mg L-1 BAP + 1 mg L-1 2,4-D (designated as BD1), 1 mg L-1 BAP + 1.5 mg L-1 2,4- D (designated as BD2), 1.5 mg L-1 BAP + 1 mg L-1 2,4-D (designated as BD3), 0.5 mg L-1 BAP + 1 mg L-1 2,4-D (designated as BD4).

Because 2,4-D has high phytotoxicity, it is possible that it should not be used as a commercial rooting substance, but there is a lack of studies on this, so the effects of this compound on the rooting of vine cuttings should be tested.

Though, dark culture conditions triggered more calli on lower levels of 2,4-D (0.5-2.0 mgL-1) compared with higher levels in Cotyledon and Hypocotyl explants, however, calli growth was greater under long days in both crops.
