Acceleration of flowering of the long-day plant Arabidopsis by 8-azaadenine.

The incorporation of 8-azaadenine (2×10(-5)M) to the aseptic culture medium reduced the time required for developing macroscopically visible flower primordia and the number of leaves appearing before the first flower buds to about half under 8 hrs daily illuumination in both wild type and a late monogenic mutant. In the presence of equimolar amount of adenine the flowering was not accelerated by the analog.
