Abstract

Provedenim istraživanjem simptomatičnih stabala poljskog jasena zabilježena je prisutnost različitih gljivičnih organizama, od kojih su neki paraziti, drugi saprofiti ili endofiti. Uzorkovana su stabla osutosti krošanja u starijoj sastojini od 45% do 70%, te u mlađoj sastojini osutosti krošanja 20% do 40%.
Provedenim izolacija iz simptomatičnog tkiva uzorkovanih stabala utvrđeno je ukupno 42 taksona gljiva, od kojih je 33 taksona identificirano do razine vrste te 9 do razine roda. Utvrđeno je da se među izoliranim taksonima nalaze značajniji uzročnici bolesti: Hymenoscyphus fraxineus, Kretzschmaria deusta, Diplodia fraxini, Diaporthe eres i Cryptosphaeria eunomia var. fraxini. Najznačajnija zabilježena vrsta je H. fraxineus koja se smatraglavnim uzročnikom odumiranja poljskog jasena u istraživanim sastojinama.

Abstract (english)

The research on symptomatic narrow-leaved ash trees revealed the presence of various fungal organisms, some of which are parasites, saprotrophs or endophytes. Trees were sampled in the older ash stand with crown transparency 45%
to 70%, and in the younger ash stand with crown transparency 20% to 40%.
A total of 42 taxa of fungi were identified from the symptomatic tissue of the sampled trees, of which 33 taxa were identified to the species level and 9 to the genus level. Among the isolated taxa followong important tree diseases were found: Hymenoscyphus fraxineus, Kretzschmaria deusta, Diplodia fraxini, Diaporthe eres and Cryptosphaeria eunomia var. fraxini. The most significant is H. fraxineus, which is considered as the main cause of the narrow-leaved ash dieback in the investigated stands.
