Werner, H.O. (1949) Effect of position within a large storage bin upon midwinter behavior of Nebraska Triumph seed potatoes (Research Bulletin: Bulletin of the Agricultural Experiment Station of Nebraska No. 158)


ISSN 0097-1489


Much variation in time of emergence of plants has been observed within lots of Nebraska seed potatoes planted in the South during the winter. In large storage bins in western Nebraska the end of the dormancy period of tubers in various parts of the bin, as determined by the appearance of sprouts, may vary from January to May. It has been surmised that differences in temperatures and perhaps other conditions in various parts of the bin may account for such variations. In the winter of 1941-42 an experiment was conducted to determine the extent to which the position of potatoes within a bin would affect the time and rate of sprout growth. This was determined by removing the potatoes from storage and promptly placing them under identical conditions in sprouting rooms held at constant temperatures, or by planting them in the South.
