Abstract
INVESTIGATIONS of the active agents in Nature inducing chromosome alterations have shown that the most effective ones are abnormal temperatures1 and obviously various parasites (cynipid wasps2, nematodes3, Eryophyes4, Tetranychus5, bacteria6, fungi7, viruses8, etc.). The latter induce abnormalities in the mitotic and meiotic processes chiefly by introducing various substances and partly by woundings, which further give rise to plants with altered chromosome complexes (including polyploidy6).
