RESUMO

Currently the arm of Brazilian agriculture, governed by flower activity, is characterized as highly profitable and promising. In this field, is increasing the use of techniques that increase the quantity and quality in the final products. Among the main products from flowers, increasing emphasis is given to the species Zantedeschia aethiopica, popularly known as Calla Lilies, who despite dominating market share considerably, little known about their behavior by hormone treatment, packaging or handling storage temperature. Thus, the objective was to evaluate the effect of gibberellic acid in rhizomes of arum, the process of packaging and maintaining them in cold storage and also of young plants in the production phytotechnical characters. To achieve this objective, three experiments. At first underwent rhizomes of arum lilly in solutions containing gibberellic acid (GA3) at concentrations of 0, 50, 100, 500 and 1000 mg L-1, using two sources of this hormone. In the second experiment, put up rhizomes in polyethylene and the set was stored at ambient conditions for up to 90 days after being planted and conduced until flowering plants. And finally the third, rhizomes were subjected to cold storage periods of 0, 10, 20, 30 and 40 days in the same way, young plants (60 days) were also stored in these conditions. It was observed that the presence of GA3 anticipates flowering and confers greater production of flowers in the same way, the storage process also increases the number flower stalks. On the other hand, the packing of rhizomes and seedlings did not affect the evaluated characteristics.
