abstract:
The purpose of the work was to examine the impact of microwave radiation on storage durability of potato tubers – Velox, Felka Bona and Vineta varieties. The scope of work covers one year of research, losses in stored tubers mass resulting from transpiration and respiration, germination, and the effect of the Rhizoctonia solani and Streptomyces scabies type storage diseases. Moreover, tuber susceptibility to mechanical damage was evaluated. Obtained research results indicate that microwave radiation significantly reduced the losses in potato tubers mass due to evaporation and transpiration, and caused an increase in germ mass. During the storage period, the tested potato varieties positively reacted to micro-wave radiation doses used in the experiment, with lower degree of infection by Rhizoctonia solani. Such an effect was not observed in the case of infection by Streptomyces scabies. The researchers observed no significant impact of microwave radiation, at applied doses and exposure times, on potato tuber periderm puncture force at its biological strength limit.
