Measurement of potato tubers resistance against mechanical loading

Measurement of the water potential of stored potato tubers.

A method of measuring the water potential of stored potato tubers (Solanum tuberosum L.) was needed to investigate the relationship of bacterial soft rot in tubers to water potential. Pressure chamber measurements, while useful for tubers with functional stolons, cannot be made on stored tubers. Measurements could be made on excised tissue pieces in a hygrometer chamber and with hygrometers imp...

Evaluation of potato tuber moth (Lepidoptera: Gelechiidae) resistance in tubers of Bt-cry5 transgenic potato lines.

The potato tuber moth, Phthorimaea operculella (Zeller), in tropical and subtropical countries, is the most destructive pest of potato, Solanum tuberosum L. The larvae attack foliage and tubers in the field and in storage. The purpose of this study was to evaluate the efficacy of a Bt-cry5 transgene to control the potato tuber moth in tuber tissues. Tuber bioassays using stored (11-12 mo old) a...

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...
