Abstract
Ophiostoma novo-ulmi je fitopatogena gljiva koja uzrokuje holandsku bolesti brijesta. Ova je bolest uzrokovala sušenje velikog broja stabala brijesta i smatra se jednom od najdestruktivnijih bolesti drvenastih biljnih vrsta. Vrsta O. novo-ulmi dijeli se na dvije podvrste: O. novo-ulmi ssp. novo-ulmi i ssp. americana. U ovom radu istražen je utjecaj različitih temperatura (16 °C, 21 °C, 25 °C i 28 °C) na fitopatogenu gljivu O. novo-ulmi. U istraživanju su testirani izolati O. novo-ulmi koji zaražavaju brijest na području Hrvatske, a koji pripadaju i jednoj i drugoj podvrsti te hibridni izolati nastali njihovim križanje u prirodi. Cilj rada bio je odrediti na kojoj temperaturi dolazi do temperaturnog stresa koji će rezultirati promjenom u brzini rasta u usporedbi s optimalnom temperaturom za rast koja za ovu vrstu iznosi 20 – 22 °C. Iako je većina izolata imala statistički značajno smanjenu brzinu rasta pri 16 °C i 28 °C u usporedbi s 21 °C, samo kod pojedinih izolata utvrđeno je smanjenje brzina rasta pri 25 °C, što se nije se mogao jasno povezati s tim kojoj podvrsti pripadaju. Dobivani rezultati ukazali su na mogućnost postojanja razlika u odgovora različitih izolata vrste O. novo-ulmi na temperaturu.
Abstract (english)
Ophiostoma novo-ulmi is a phytopathogenic fungus that causes Dutch elm disease. This disease caused the drying of a large number of elm trees and is considered to be one of the most destructive diseases of woody plant species. The species O. novo-ulmi is divided into two subspecies: O. novo-ulmi ssp. novo-ulmi and ssp. americana. In this study, the influence of different temperatures (16 °C, 21 °C, 25 °C, and 28 °C) on the phytopathogenic fungus O. novo-ulmi was investigated. The O. novo-ulmi isolates from Croatia belonging to both subspecies as well as hybrid isolates resulting from their hybridization in nature were tested in the study. The aim was to determine at what temperature the stress will occur resulting in a change in the growth rate compared to the optimal temperature for growth, which is 20-22 °C. Although most isolates had a significantly reduced growth rate at 16 °C and 28 °C compared to 21 °C, only some isolates showed a decrease in growth rate at 25 °C, which could not be clearly linked to their subspecies determination. The obtained results indicated the possibility of differences in the response of different O. novo-ulmi isolates to temperature.
