Morphological variability of achenes of some European populations of Lactuca serriola L.

Popis výsledku v původním jazyce

This study focuses on the morphological variability of Lactuca serriola achenes in relation to ecogeographic features. Fifty L. serriola populations from four European countries, Czech Republic, Germany,the Netherlands and United Kingdom, were studied. Five morphological characters of the achenes - length and width of achene, length/width index, length of beak, and number of ribs - were evaluated. Significant differences exist in achene morphology of two leaf forms of L. serriola, forma serriola and forma integrifolia. Achenes of f. serriola are shorter, thinner, shorter beaked, lower length/width index, and higher number of ribs compared to f. integrifolia. There was significant variation in the measured characters. Statistical analysis indicated thatachene length and width increased along an east-west transect from 2.95 to 3.35mmand 0.93 to 1.00mm, respectively. Mean beak length had a similar trend with the exception of German achenes. They had shorter beaks than achenes originating
