1. Desenvolvimento in vitro e imunolocalização de 5-metilcitosina em raízes tuberizadas e não-tuberizadas de Viguiera arenaria Baker (Asteraceae) / In vitro development and immunolocalization of 5-methylcytosine in tuberized and nontuberized roots of Viguiera arenaria Baker (Asteraceae)
Viguiera arenaria Baker is an herbaceous Asteraceae from Cerrado presenting alternate phyllotaxis, capitulum inflorescence and tuberized roots. Although phytochemical analyses have found substances with biological activities of therapeutic interest, little is known about the biology of the plant. In this study, we sought to contribute to the knowledge of asp

2. Produtividade e Qualidade de TubÃrculos de Batata Sob Diferentes Doses e Parcelamentos de NitrogÃnio e PotÃssio / Productivity and quality of potato under different split application and doses of mineral fertilization
With the purpose of assessing the effect of doses and application times of mineral fertilizers on the production and quality of potato cultivars, this experiment was carried out at Fazenda Progresso II in the municipality of MucugÃ-BA and at the Universidade Estadual do Sudoeste da Bahia - UESB, in VitÃria da Conquista - BA. 3 doses of N and K were used (7

3. Tolerance to salt and thermal stresses in cultivars of taro and cassava tuberized in vitro / Tolerância aos estresses salino e térmico em cultivares de taro e mandioca tuberizadas in vitro
A tuberização é um complexo processo de desenvolvimento que é influenciado por variáveis genéticas, ambientais e fisiológicas, sendo caracterizado por significativas mudanças anatômicas, hormonais e bioquímicas. Nesse sentido, a microtuberização in vitro, além de sua importância pela rápida propagação vegetativa das plantas livres de doença

4. Morphophysiological description of early and late potato clones aiming at adaptation to tropical conditions. / DescriÃÃo morfofisiolÃgica de clones de batata precoces e tardios visando a adaptaÃÃo a condiÃÃes tropicais
The objective of this research was to study the growth, tuberization and dry matter partitioning to tubers of early and late potato clones during the vegetative growth. Besides, it was studied the viability for using morphophysiological traits as parameters to select clones more adapted to tropical conditions. Two clones from each maturity class were used, C

5. Cultura in vitro da especie do cerrado Sinningia allagophylla (Martius) Wiehler (Gesneriaceae) : enraizamento, tuberização e nutrição com enfase em aluminio / In vitro cultivation of cerrado species Sinningia allagophylla (Martius) Wiehler (Gesneriaceae) : rooting, tuberization and nutrition with emphasis in aluminium
Sinningia allagophylla (Gesneriaceae) é uma herbácea perene amplamente distribuída no Brasil, encontrada principalmente em formações campestres do Cerrado, bem como em alguns afloramentos rochosos da Mata Atlântica, crescendo, assim, em ambiente inóspito (sujeito à seca e ao fogo, em solos ácidos, deficientes em nutrientes e com teores elevados de a

6. Effect of Carbon Dioxide and Ethylene on Tuberization of Isolated Potato Stolons Cultured in Vitro1
Carbon dioxide stimulates tuberization of isolated potato (Solanum tuberosum L.) stolons cultured in vitro. The stimulatory effect is inhibited by C2H4 which is by itself also inhibitory of tuberization. Furthermore, C2H4 inhibits kinetin-induced tuber initiation. Both the formation and elongation of roots are inhibited by C2H4. The antagonistic actions of C

7. Studies on the Carbon Dioxide Promotion and Ethylene Inhibition of Tuberization in Potato Explants Cultured in Vitro1
Ethylene inhibited the tuberization of etiolated potato (Solanum tuberosum L. var. Red La Soda) sprout sections cultured in vitro. Carbon dioxide did not overcome the C2H4 inhibition but it was required for normal tuberization. Ethylene totally prevented root formation and development. It inhibited stolon elongation, and caused thickening and diageotropical

8. Far-Red Reversal of Red Light Effect during Long-Night Induction of Potato (Solanum tuberosum L.) Tuberization 1
The hypothesis that phytochrome is involved in the regulation of potato (Solanum tuberosum L.) tuberization was tested. When 5 minutes of red light were given in the middle of the 16-hour dark period to which whole plants were exposed daily for 14 days before making cuttings, the percentage of tuberization on cuttings decreased. The effect of red light was s

9. Effects of Extracellular Extracts from Leaves on the Tuberization of Cuttings of Potato (Solanum tuberosum L.)
Extracellular extracts from leaves were applied to moderately induced cuttings of potato. The more inductive cycles the plants from which the leaf extracts were obtained had experienced, the lower the percentages of tuberization in thcuttings and the lower the tuber yields on the central buds.

10. Phytochrome B Affects the Levels of a Graft-Transmissible Signal Involved in Tuberization1
Grafting experiments between phytochrome B antisense and wild-type potato (Solanum tuberosum L. subsp. andigena [line 7540]) plants provide evidence that phytochrome B is involved in the production of a graft-transmissible inhibitor of tuberization, the level of which is reduced in the antisense plants, allowing them to tuberize in noninducing photoper

11. The Role of Gibberellin, Abscisic Acid, and Sucrose in the Regulation of Potato Tuber Formation in Vitro1
The effects of plant hormones and sucrose (Suc) on potato (Solanum tuberosum L.) tuberization were studied using in vitro cultured single-node cuttings. Tuber-inducing (high Suc) and -noninducing (low Suc or high Suc plus gibberellin [GA]) media were tested. Tuberization frequencies, tuber widths, and stolon lengths were measured during successive stage
