Flower bud formation in the potato plant as influenced by variety, size of seed piece, and light

  • Published:
American Potato Journal Aims and scope Submit manuscript

Summary

The number of young buds that develop in the first inflorescence of the potato is influenced by variety, size of seed piece, and light treatment. Fewer buds were initiated in plants from 5-gram seed pieces than from 25- and 45-gram pieces, and from plants grown in total darkness than in plants exposed to natural daylight.

No increase in the number of buds differentiated was obtained by lengthening the natural photoperiod with Mazda light of low intensity. An increase significant to the I-per cent level was obtained from two collections made in dull, cloudy weather by lengthening the natural photoperiod with fluorescent light of higher intensity.
