It is a continuation of the previous paper (Mehra and Dhiman, this journal) dealing with induced "meiotic reductions". In this paper are described the effects of purine derivatives aminophylline, theophylline, adenine, adenosine, as well as DNA on root-tip cells of Pterotheca falconeri. Besides "meiotic reductions", reductional groupings were also noticed and their percentage is recorded. In regard to mitotic index aminophylline and DNA failed to show any correlation with con-centration and treatment periods. But DNA at 7%/1 HT/96 HR and 8%/2 HT/48 HR was lethal to the root-tips. However, it was different with adenine, adenosine and theophylline where the mitotic index was concentration and treatment period dependent. There was decrease in mitotic index with increase in concentration or the treatment period.
