W pływ gleby z poboczy ulic na zdolność kiełkowania i niektóre cechy morfologiczne siewek wybranych gatunków roślin [The influence of soil from the side space of the street on germination capacity and some morphological characters of seedlings of selected plants species]

Abstract

Germination capacity, length of roots and seedlings and air-dry matter of plants of soybean, cucumber, buskwheat, winter wheat and white mustard were estimated in four soil material: bare soil and grass-covered soil from a side-space ofroads with heavy traffic, soil from a farming field and washed, calcinated sand (pure sand). Highest germination capacity of investigated plants was found on pure sand. Seedlings germinated on soil from the grassy side space of the street had longer aboveground parts in comparison with those germinating on other soil material. Significantly smaller length of abovegro und parts of seedlings were found on the object with washed and calcinated sand. On the pure sand, plant seedlings formed higher air-dry matter in comparison with the soil from a farming field. Independently of soil material, soybean and winter wheat seedlings formed the longest roots, aboveground parts and highest content of air-dry matter. On the soil from the grassy side space of the street roots of seedlings were significantly longer than roots of seedlings germinated on soil from a farming field. Greater content of some heavy metals in soil from side space ofthe street had no influence on germination capacity and investigated morphological characters of tested plants.
