Biochemical changes in affected potato tubers

Characterization and Epidemiological Significance of Potato Plants Grown from Seed Tubers Affected by Zebra Chip Disease

Tuberborne diseases of potato, such as Potato virus Y and Potato leafroll virus, present significant problems for potato seed growers and producers alike. An emerging disease of potato, called “Zebra Chip” or “Zebra Complex” (ZC), has recently appeared in the United States and elsewhere and is causing significant losses to individual growers and processors. First identified in northeastern Mexi...

Physiological and Biochemical Regulation of Dormancy and Sprouting in Potato Tubers (Solanum tuberosum L.)

At harvest, potato (Solanum tuberosum L.) tubers are in a dormant state and do not have the ability to sprout. After harvesting, tuber dormancy is released progressively. This release is accompanied by numerous physiological and biochemical changes, such as carbohydrate hydrolysis and the accumulation of saccharides, which are detrimental to the nutritional and processing qualities of potatoes....

Structure of potato tubers formed during spaceflight.

Potato (Solanum tuberosum L. cv. Norland) explants, consisting of a leaf, axillary bud, and small stem segment, were used as a model system to study the influence of spaceflight on the formation of sessile tubers from axillary buds. The explants were flown on the space shuttle Columbia (STS-73, 20 October to 5 November 1995) in the ASTROCULTURE (TM) flight package, which provided a controlled e...

Stimulation of Wound Reactions in Potato Tubers by Thiabendazole

Thiabendazole (TBZ), an antifungal and antihelmintic benzimidazole derivative, after 6 min treatment with a 0.1 m M aqueous solution enhances C 0 2 release in intact potato tubers for up to two hours. There are also indications for a reduced water permeability of isolated periderm layers from TBZ treated potato tubers. Potato slices (ca. 3 mm thick) or discs (with ca. 5 mm diameter) from potato...
