Abstract In a field trial in the Negev, Israel, and 2 greenhouse trials in Wageningen, Netherlands, in 1989, potato cultivars with different dormancy periods were stored at a constant 18 degrees C, a constant 28 degrees, 20 d at 28 degrees and subsequently at 18 degrees (10 d at 0 degrees, 10 d at 28 degrees and subsequently at 18 degrees in 1 experiment), or 20 d at 2 degrees and subsequently at 18 degrees. In all but 1 cultivar storage at 28 degrees gave superior growth vigour (earlier emergence, more stems/tuber, faster initial growth and earlier tuber initiation) at early plantings (less or =120 d after haulm removal (DAH)) than the other storage regimes. However, this treatment was detrimental to cultivars such as Draga with a long dormancy period and a rapid rate of physiological aging. Growth vigour was also advanced by hot or cold pretreatment, and was lowest with storage at 18 degrees. At later plantings (up to 180 DAH), the differences between the regimes decreased.
