Germination of weed species from Asteraceae family under water deficit conditions

Original language description

In 2006 and 2007, the influence of water deficit conditions on germination of seeds from Asteraceae family was observed. The germination of achenes of Arctium tomentosum, Artemisia vulgaris, Conyza canadensis, Galinsoga parviflora, Lactuca serriola, Senecio vulgaris, Sonchus asper, Sonchus oleraceus, Taraxacum sect. Ruderalia and Tripleurospermum inodorum was evaluated in laboratory conditions. The values of soil water potential were 0, -0.05, -0.1 and -0.5 MPa. For simulation of water stress polyethylenglycol (PEG 6000) solution was used (different concentrations). The germination was daily assessed during 21 days at temperatures 10, 15 and 20°C. At the end, germination of achenes (%) and the value T50 was determined (number of days necessary for germination of 50 % seeds). The aim of work was to prove the ability of achenes to germinate under water deficit conditions. Seeds of Conyza canadensis, Galinsoga parviflora, Lactuca serriola and Tripleurospermum inodorum germinated the most.
