Abstract

The Effect of Nitrogen and Saccharose on Tuberizationin Vitro. The tuberization rate increased and tuber mass decreased to one half or one quarter in potato plantlets in a modified MS-medium with 3 % saccharose and decreased nitrogen content in comparison with normal MS-medium. Decreasing nitrogen content prolonged the time necessary for tuberization. The increase of sucrose concentration to 4 % decreased the inhibitory effect of higher contents of nitrogen on tuberization rate.
