ABSTRACT
We have studied the primary root development of the one of the most important grass weeds - large crabgrass (Digitaria sanguinalis (L.) Scop). The primary, secondary and tertiary root development was studied in laboratory (thermostat), and in pots in 1994, 1995 and 1997. Each year we sowed the seeds 1 cm deep in the pots separately. The number of days required for the change of the early root system from the sowing 17 - 24 days. The average leaf number in the root change period was 4 and varied in between 3 to 5. We also observed that the date of sowing during the summer months (June, July and August) did not influence the change of the early root system.
