Resumo: | ABSTRACT:  Lavender is an aromatic ornamental plant that is used widely in the perfume, pharmaceutical, cosmetical and food industries. That is why it is important to study ways to promote a production of lavender raw material. For this, four experiments were carried out in order to study the germination and initial in vitro development of lavender. In the first part the efficiency of the use of hydrogen peroxide in the pre-treatment of seeds inoculated in culture media with different concentrations of gibberellic acid was evaluated. Besides that, the influence of the use of Growlux lamps and white fluorescent lamps on plantlets cultivated in MS and LS media at salts concentrations of 50 and 100% was evaluated. Finally, the effect of the gibberellic acid, putrescine, spermine and spermidine in different concentrations was evaluated. Better results were estimated when hydrogen peroxide pretreatment was applied to the seeds with subsequent inoculation in a medium containing 2,5 mg L-1 of gibberellic acid. The use of Growlux lamps did not influence the characteristics observed when compared to the use of white fluorescent lamps, however it was concluded that the species develops more in a LS medium. Concerning the use of polyamines was found that germination, aerial part and number of leaves of the seedlings were generally favored at the concentration of 0,5 mg L-1 except when spermine was applied, which resulted in a lower number of leaves under this condition.
