Description
| - Počet druhů a jejich pokryvnost v plevelových společenstvech v letech 1955–2000 poklesla a tento pokles byl výraznější v chladných a středně teplých fytogeografických oblastech. Půdní typ nemá vliv na počet druhů plevelů, ovlivňuje však jejich pokryvnost; na živinami chudých půdách pokryvnost klesá se vzrůstající pokryvností plodiny. Kukuřice má druhově nejchudší plevelová společenstva, okopaniny a pícniny nejbohatší. Rozdíly v plevelové flóře jsou způsobeny specifickým typem obhospodařováním a jeho změnami v posledních 50 letech. (cs)
- Number and cover of agricultural weed species decreased from 1955 to 2000, more so in the moderate-to-cold than in the warm altitudinal floristic region. There was no direct effect of soil type on weed species number, whereas the decrease of weed cover with increasing crop cover was more pronounced on nutrient-poor than nutrient-rich soils. Maize fields contained the lowest number of weed species, while root crops and fodder plants were most species rich. The differences in weed flora are attributable to management and crop-specific agricultural practices as well as general changes in the management of arable fields over the last decades.
