The glycoalkaloid content in potato tubers (Solanum tuberosum) as affected by cultivation technology and mechanical damage
1997
Zrust, J. (Vyzkumny Ustav Bramborarsky, Havlickuv Brod (Czech Republic))
In 1994 - 1996 the field trial with three potato varieties (Krystala, Karin, Arnika) was carried out to study the varietal differences, effects of the year, some methods of cultural practices, mechanical damage and length of storage on the content of alpha-chaconin and alpha-solanine. It was found that the year has greater effect on GA content than the variety. Mechanical damage of tubers increased highly significantly the total GA content compared with undamaged tubers in all three varieties. Post-emergently applied herbicide and chemical protection against potato late blight did not give unambiguous results compared with mechanical cultivation or treatment without protection against potato late blight in different years. Differences in GA content were not significant in tubers in samplings during storage.
