The toxicity of trichlorfon and dichlorvos to initial growth processes, such as germination and seedling growth, and to chromosomes of embryonic shoot meristems and sporogenous tissue was assessed by the progeny test of H. vulgare. The methodology involved in the test is described. Dichlorvos was more effective than trichlorfon, whose effects sometimes even surpassed those of EMS [ethyl methanesulfonate]. The frequency of late effects in the PMC [pollen mother cells] was higher than that of the initial effects in the ESC [embryonic shoot cells]. Probable reasons for this differential cellular behavior, and the consequences of the chromotoxic responses, are discussed.
