Description	The perennial weed Elytrigia repens is most important and widely spread in the Czech Republic. Increasing trend of occurrence of this weed on arable land since 1990 was caused mainly by minimal tillage, unsuitable crop rotations and by using non effective herbicides. Experiments were planted in April (2004 and 2005). In two year pot's experiments we have studied vegetative reproduction activity. Pots 45 cm in diameter and 50 cm in height were used for experiments. Plants were set out in a potting substrate consisting of 1/3 orthic luvisoil, 1/3 sand and 1/3 peat substrate. Pot experiments were focused on studying vegetative reproduction of Elytrigia repens. Elytrigia repens plants were grown in containers and length of rhizomes, weight of above ground and under ground part of plants were measured at regular time intervals (May, June, July, August, September and October) every year. One plant of Elytrigia repens produced 3630 cm of rhizomes, 162 g of above ground matter, 95 g of under ground mat The perennial weed Elytrigia repens is most important and widely spread in the Czech Republic.

Sledována byla délka oddenků, hmotnost hořenů i nadzemní hmoty V roce 2004 byla tvorba nadzemní hmoty 95,4 g a v roce 2005 116,3 g. (cs)
