Prikazana
je sedanja razširjenost dveh rj na nebinovkah (Asteraceae) v Sloveniji, Puccinia
distincta McAlpine na marjeticah (Bellis
perennis L.) in Puccinia lagenophorae
Cooke na navadnem grintu (Senecio vulgaris
L.). Opisane so diagnostične značilnosti obeh vrst rj na vzorcih iz Slovenije.
Terenska opazovanja nakazujejo, da je P. lagenophorae že dobro ustaljena po vsej Sloveniji, P.
distincta pa je nedavni prišlek, ki se še širi po deželi. Čeprav imata
obe vrsti opsis-obliko življenjskega kroga z eciosporami kot nosilci okužb in
imata mnoge morfološke značilnosti enake, pa njuna različna epidemiologija
podpira njuno uvrstitev v dve različni vrsti.
ABSTRACT
Puccinia distincta and Puccinia lagenophorae, two rust fungi of Asteraceae recently introduced into Slovenia
The
current distribution of two rust fungi on Asteraceae,
Puccinia distincta McAlpine on wild
daisies (Bellis perennis L.) and Puccinia
lagenophorae Cooke on groundsel (Senecio
vulgaris L.), is described for Slovenia. The diagnostic features of both
rust species are described using Slovenian material. Field observations suggest
that P. lagenophorae is well-established across Slovenia whereas P.
distincta is a recent arrival still spreading across the country. Although
both species have an opsis-type life-cycle with aeciospores as the main carrier
of infection and also share many morphological features, their different
epidemiologies support their classification as two distinct species.
