Niektóre recesywne gatunki chwastów zbóż na erodowanych glebach lessowych Płaskowyżu Nałęczowskiego
Streszczenie
A list of 34 recessive weed species occurring on loessial soils of
the Nałęczów Plateau was prepared on the basis of investigations carried out in
1987-1990 and literature data from 1948-1958. The list includes: 1 extinct (Bromus
arvensis), 3 critically endangered, 8 endangered, 10 vulnerable and 4 low risk species.
There is too little information on 8 species to make an assessment of their risk of
extinction.
