INFLUENCE OF TEMPERATURE AND pH OF NUTRITION MEDIA ON GROWTH OF BOTRYTIS CINEREA

U radu je istraživan utjecaj razliĉitih temperatura (15, 22, 30°C) i tri razliĉite pH vrijednosti PDA podloge (5,5, 6,5 i 7,5) na razvoj gljive Botrytis cinerea koja je uzroĉnik sive plijesni. Gljiva se razvijala statistiĉki vrlo znaĉajno bolje na temperaturama 15 i 22°C u odnosu na porast gljive na 30°C. Na temperaturama 15 i 22°C micelij je već sedam dana od nacjepljivanja ispunio Petrijevu zdjelicu bez obzira na pH podloge. Na 30°C i nakon ĉetrnaest dana od nacjepljivanja promjer micelija je bio manji od 2 cm bez obzira na kiselost podloge. Na temperaturi 30°C razvoj Botrytis cinerea na pH 6,5 bio je statistiĉki vrlo znaĉajno bolji u odnosu na porast micelija na pH 8,0. Na temperaturama 15 i 22°C gljiva se jednako dobro razvijala na u svim varijantama pokusa bez obzira na kiselost podloge.In this thesis we investigated the effect of different temperatures (15, 22, 30°C) and three different pH values (5.5, 6.5 and 7.5) on the development of the fungus Botrytis cinerea. The fungus developed statistically significantly better at 15 and 22°C in relation to the growth of the fungus at 30° C. At 15 and 22°C seven days from inoculation the mycelium filled Petri dishes (regardless of the pH value of the substrate). After fourteen days from the inoculation at 30°C mycelium diameter was less than 2 cm regardless of the pH value of the substrate. The development of Botrytis cinerea at 30°C and at pH 6.5 was statistically significantly better in comparison to the growth of mycelium at pH 8.0. At 15 and 22°C fungi are equally well developed on the all treatments regardless of the acidity of the substrate
