1. Influência do dano físico na fisiologia pós-colheita de folhas de taioba
Folhas de taioba danificadas fisicamente tornam-se amarelas e escuras na região do dano. Assim, o objetivo deste trabalho foi avaliar o efeito do dano físico sobre o metabolismo pós-colheita de folhas de taioba. Para esse fim, avaliou-se o teor de clorofila e o acúmulo de compostos fenólicos solúveis em discos foliares de taioba que continham furos rea

2. Efeito do dano físico sobre o metabolismo de folhas de taioba, Xanthosoma sagittifolium (L.) Schott / Effects of wounding on the metabolism of tannia leaves, Xanthosoma sagittifolium (L.) Schott
Vegetables like leaves of tannia are subject to various factors which cause deterioration. Among these factors, mechanical damage triggers a series of physiological responses that occur at the site of the injury and surrounding tissues. The objective of this study was to evaluate the physiological responses of tannia leaves mechanical damaging, and whether t

3. In vitro propagation of tannia (Xanthosoma sagittifolium (L.) Schott) accessions / Propagação in vitro de germoplasma de taioba (Xanthosoma sagittifolium (L.) Schott)
With the objective to establish the in vitro propagation and to evaluate the behavior of tannia varieties, it was applied growth regulators concentrations and cultivation ways of propagation. They were evaluated the number of shoots (NB), length of the aerial part (CPA), length of the longest root (CR), weight of the total fresh matter (MF) and total drought

4. The major tuber storage protein of araceae species is a lectin. Characterization and molecular cloning of the lectin from Arum maculatum L.
A new lectin was purified from tubers of Arum maculatum L. by affinity chromatography on immobilized asialofetuin. Although this lectin is also retained on mannose-Sepharose 4B, under the appropriate conditions free mannose is a poor inhibitor of its agglutination activity. Pure preparations of the Arum lectin apparently yielded a single polypeptide band of
