1. Avaliação e adequação da lavagem no beneficiamento da batata / Assessment and adequacy of washing in the potato processing
The washing for potatoes in São Paulo, for the fresh market or industry, consumes excessive amounts of water, causing damage to the environment mainly due to waste water discharge from the washing step. Considering the requirement of the consumer market for washed potatoes, and the need to reduce water consumption, the hypothesis is that it is possible to r

2. Efeitos da maturidade, do peso da batata-semente e da quebra da dormencia sobre a cultivar de batata (Solanum tuberosum L.) Itarare (IAC 5986).
Estudou-se no trabalho, os efeitos da maturidade, do peso da batata-semente e da quebra da dormencia, sobre a brotacao, o desenvolvimento e a producao da cultivar Itarare (IAC 5986). Batatas-sementes foram multiplicadas em 17/4/91 e colhidas em duas epocas: precoce (CP), aos 70 dias apos a emergencia, e maturacao natural (MN), apos a morte da parte aerea. As

3. Oxidative Stress Results in Increased Sinks for Metabolic Energy during Aging and Sprouting of Potato Seed-Tubers.
Glutathione-mediated free-radical-scavenging and plasma membrane ATPase activities increase as sinks for metabolic energy with advancing tuber age. Plasma membrane ATPase activity from 19-month-old tubers was 77% higher than that from 7-month-old tubers throughout sprouting. The higher activity was not attended by an increase in the amount of ATPase per unit

4. Effects of Oxygen and Respiratory Inhibitors on Induction and Release of Dormancy in Aerial Tubers of Begonia evansiana
Effects of O2 and some respiratory inhibitors on the induction and release of bud dormancy were examined with the aerial tubers of different ages of Begonia evansiana Andr. Oxygen was needed not only for tuber sprouting but also during the chilling process at 2 to 5 C to break tuber dormancy. If the mature tubers were exposed to blue light during the chillin

5. Involvement of Ethylene in Potato Microtuber Dormancy
Potato (Solanum tuberosum L.) single-node explants undergoing in vitro tuberization produced detectable amounts of ethylene throughout tuber development, and the resulting microtubers were completely dormant (endodormant) for at least 12 to 15 weeks. The rate of ethylene production by tuberizing explants was highest during the initial 2 weeks of in vit

6. Correlation between Changes in Mitochondrial Membranes of Artichoke Tubers and Their Hardening and Dormancy
Spin labeling studies using mitochondrial membranes of Jerusalem artichoke (Helianthus tuberosus L.) showed that the decrease during winter in the temperatures of the upper and lower lipid transitions correlated with the development of freezing hardiness of the tubers. The killing temperature for tuber tissue reached a minimum of −12 C, about 5 C degrees l

7. Comparative Analyses of Potato Expressed Sequence Tag Libraries1
The cultivated potato (Solanum tuberosum) shares similar biology with other members of the Solanaceae, yet has features unique within the family, such as modified stems (stolons) that develop into edible tubers. To better understand potato biology, we have undertaken a survey of the potato transcriptome using expressed sequence tags (ESTs) from diverse tissu

8. Seasonal Changes in the Structure and Function of Mitochondrial Membranes of Artichoke Tubers: Acyl Fatty Acid Composition and the Effect of Growth Conditions
Changes in the temperature response, fluidity, function and the acyl fatty acid composition, were determined for a mitochondria-rich membrane fraction from Jerusalem artichoke (Helianthus tuberosus L.) tubers during dormancy for a crop which matured in midsummer. The temperature of both the upper and lower limits of the membrane lipid transition decreased du

9. Seasonal Changes in the Structure and Function of Mitochondrial Membranes of Artichoke Tubers: A Requisite for Surviving Low Temperatures during Dormancy
The temperature limits of the order-disorder transition, and the Arrhenius activation energy of succinate oxidase activity for mitochondria of Jerusalem artichoke (Helianthus tuberosus L.) tubers were determined from the initiation to the termination of dormancy. The temperature limits for the transition at the initiation of dormancy were 25 and 3 C. These c

10. Changes in Lipid Peroxidation and Lipolytic and Free-Radical Scavenging Enzyme Activities during Aging and Sprouting of Potato (Solanum tuberosum) Seed-Tubers.
Previous research has shown that cell membranes of potato (Solanum tuberosum L. cv Russet Burbank) seed-tubers lose integrity between 7 and 26 months of storage (4[deg]C, 95% relative humidity), and this loss coincides with a significant decrease in growth potential. The age-induced decline in membrane integrity is apparently due to increased peroxidative da
