Population dynamics of ramets Allium ursinum l. in south-western Slovakia
Allium ursinum (Liliaceae) is bulbiferous spring ephemeroid and geophyte with underground organs bulbs. Population dynamics of Allium ursinum ramets were studied in woodland communities (with Acer campestre, Acer pseudoplatanus. Fraxinus excelsior) in park in Hlohovec (SW Slovakia) on four permanent...

| Tartalmi kivonat: | Allium ursinum (Liliaceae) is bulbiferous spring ephemeroid and geophyte with underground organs bulbs. Population dynamics of Allium ursinum ramets were studied in woodland communities (with Acer campestre, Acer pseudoplatanus. Fraxinus excelsior) in park in Hlohovec (SW Slovakia) on four permanent plots (025 x 025 m) during growing seasons (2001- 2003) in 14-days interval. Field measurements we realized with usual methods of population biology (Harper, 1977). Analyzed plots were selected by random selection. Observed characteristics were - density of populations (individual, lm'2 ) and size structure of population. Self-infilling was observed to second census (in March) and than decrease density ramet between 5. and 6. census (in May). In April 2003 we observed the highest average densities (720 i.). Maximum average plant size was observed in 2002 (275 mm), this years was externally humid and minimum in 2003 (229 mm). In April 2003 we noted 53% seedling of total number ramets (1056 i) on fourth permanent research plots. |
