Resumo: | Lateral shoots of the Aloe vera (L.) Burm. cultivated in vitro, without addition vegetal regulators, for 90 days, were inoculated in MS culture-medium, containing or not spermine and/or spermidine. After 30 days of cultivation, the plants were submitted to biochemical analysis together with micropropagated plants - that were under in vitro cultivation for 90 days - (denominated as characterization), and matrix plants (in vivo). The levels of free polyamines, total phenols, total flavonoids, and the activity of peroxidase were evaluated in the biochemical analyses. The exogenous application of spermidine have promoted large number of shoots. Spermidine and spermine have promoted, when associated, an increase in the number of shoots as well as an increase of the contents of putrescine and and flavonoids. The putrescine has presented the most significant alterations, enabling to be utilized as marker of morphogenesis in the micropropagated Aloe vera. Tissues under active growth have presented high activity of peroxidase as well as those with greater rate of oxidation. In these tissues, there were noticed also higher contents of total flavonoids, indicating the need of antioxidative compounds. The action of polyamines jointly tseemed to be benefic for the shooting of micropropagated Aloe vera. |
