The influence of different temperatures and exposition time on potato tuber sprouting

Abstract

Research on the influence of different temperatures and exposition time on potato tuber sprouting was carried out at the Laboratory of Food Raw Materials, Agronomic and Zootechnical Research, Faculty of Agronomy, Lithuanian University of Agriculture, in the year 2009. Chemical analyses of potato tubers were carried out at the Laboratory of Chemical Research, Institute of Agriculture, Lithuanian Research Centre for Agriculture and Forestry. Different temperatures -10°C - +50°C influenced the tubers sprouting. The highest number of sprouts, compared to the primary number of eyes, was established in the tubers of potato cv. ‘Goda’ exposed to -10°C for 60 min. (192.6%) and to +50°C for 90 min. (194.7%); and in the tubers of potato cv. ‘Solara’ exposed to -10°C for 60 min (126.1%) and to +30°C for 60 min (167.8%).
