Summary
Sprout and root growth of potato seed pieces representing ten varieties was studied in the range of 45–60° F. The critical temperature for growth was in the 48–50° range. No consistent association between early maturity and rapid seed-piece germination could be determined.
Excellent sprouting and reasonable root growth did occur at 50°, so that a critical growth temperature for potato seed pieces of 50° F. is proposed.
