THE INFLUENCE OF NUTRITION MEDIA AND TEMPERATURE ON Sclerotinia sclerotiorum DEVELOPMENT

Abstract

Cilj istraživanja bio je utvrditi utjecaj hranjive podloge (krumpir dekstrozni agar (PDA), podloga od mrkve) i temperature (15, 22 i 30ºC) na rast i razvoj micelija i formiranje sklerocija gljive Sclerotinia sclerotiorum. Istraživanje je provedeno u laboratorijskim uvjetima 2013. godine. Statističkom obradom podataka utvrđeno je da podloga i temperatura značajno utječu na porast micelija i formiranje sklerocija. Utvrđen je statistički značajno bolji razvoj micelija na PDA podlozi te na temperaturama 15 i 20ºC, nego na drugom ispitivanom supstratu i temperaturi 30ºC. Sklerociji su se, također, formirali samo na PDA podlozi i na dvije niže temperature. Sklerociji formirani na 15ºC bili su veći od sklerocija formiranih na 20ºC.The aim of this study was to investigate the influence of nutrition media (PDA, carrot agar) and temperature (15, 22 and 30ºC) on growth and mycelium development As well as sclerotium formation of Sclerotinia sclerotiorum. The experiment was set up under laboratory conditions in year 2013. Statistical analysis showed that nutrition media and temperature had significant influence on mycelim development and formation on sclerotia. Mycelial growth was significantly higher on PDA and at 15 and 20ºC. Sclerotia are formed only on PDA and the two lower temperatures. Sclerotia formed at 15ºC were bigger than sclerotia formed at 20ºC
