At the stubble-fields, especially maintained through a long period
after the cereal harvest, there are numerous segetal flora species which often are
not meet in the crop canopy. A status of these flora species is usually different
than in crop canopies. The cereals, as the cultivated plants, undergo different weed
control field operations which limit the level of weed infestation or even eliminate
some of the weed species from a canopy. The stubble-field conditions (warmth,
light, rain and lack of competition) are conducive to weed emerging from soil seed
bank as well as growing up and ending reproduction of those present in vegetation.
It seems that stubble-field flora could be an important and rich source of information
about species listed or suspected as endangered with extinction. In respect of the
Polish endangered weed species list, 43 weed species were found on different soil
units in the Kielce region. Only about 70% of them had diaspores in the soil (some
with soil seeds were absent in overground regions). Most species in the E, V, and
R categories of threat shoved critically low stability degrees and indice covers.
However, from the indeterminate threat group, I, a few occured in high (III—IV)
stability degree and deposited huge numbers of seeds in the 0-30 cm soil layer.
