The occurrence of annual life forms in different weed beet populations in the Czech Republic

Original language description

Weed beet (Beta vulgaris subsp. maritima x subsp. vulgaris) is a serious problem in beet production areas of the Czech Republic. It was introduced into our agroecosystems as a seed impurity when the beet seed started to be imported from southern Europeancountries inside the native range of wild sea beet (B. vulgaris subsp. maritima, syn. B. maritima). It has spread rapidly through sugar beet fields and is a limiting factor of sugar beet production. Beet as a crop is a typical biennial plant with some individuals bolting in the first year of vegetation. Bolting occurs usually as a reaction to environmental conditions ? mostly low temperature during critical phase of ontogenesis. Wild sea beet is the second of weed beet progenitors and appears as annual, biennial or perennial herb. The weed beet is widely reported to be annual. This is one of the most significant biological properties to make it a serious weed. In field crop stands, biennial or perennial forms are not able to reproduce
