Vztah hustoty porostu ozimých plodin a intenzity zaplevelení v provozních podmínkách
 Punčochář, Radek
Weed infestation was carried out in the vegetation of oilseed rape and winter wheat in the operating conditions. The aim was to observe a difference between between autumn and spring in the weed species composition in individual crops. Species Chenopodium strictum and Thlaspi arvense were identified in the vegetation of oilseed rape in autumn and species Capsella bursa-pastoris and Tripleurospermum inodorum during spring. Species Euphorbia cyparissias, Stelaria media and Rumex crispus were found in winter wheat during autumn. Results, which are not statistically significant, show that there is a relation between the density of winter crop vegetation and the weed species composition. Species Chenopodium strictum, Thlaspi arvense, Triticum aestivum and Tripleurospermum inodorum occurred in sparse population of oilseed rape. Species Lycopsis arvensis and Polygonum arenastrum were found in denser vegetation of oilseed rape. Species Avena fatua, Stelaria media and Thlaspi arvense were observed in sparse population of winter wheat and in denser species Geranium dissectum and Erodium cicutarium.
