Тема: Daucus guttatus
Повторный посев 2017 года семян, собранных в Дагестане в 2015 году. К сожалению, в наших условиях семена не вызревают, особенно летом 2017 года.

Alien species, was recorded for Russia for the first time. This
annual species of Daucus is widespread in the eastern Mediterranean
basin and belongs to the Daucus guttatus complex, which contains
five similar annual species (Martínez-Flores & al, 2016). Daucus
guttatus perhaps has two cytotypes. Chromosome number of 2n = 22
(n = 11) was determined for the plants from Greece (Engstrand, 1970;
Constance & al., 1976; Strid & Franzen, 1981), 2n = 20 (n = 10) for the
plants from Bulgaria, Cyprus and Turkey (Ceschmedjiev, 1983; Vogt &
Aparicio, 1999; Shner & al., 2004a). Our chromosome data confirms
the second cytotype, we also found in some cells B-chromosomes.
