Uticaj različitih podloga na porast micelije gljive Cryphonectria parasitica (Murrill) M.E. Barr

Abstract

Poznato je da se na pitomom kestenu razvija veliki broj parazitskih i saprofitskih gljiva. Ipak, najveće štete izaziva C. parasitica koja izaziva "rak kore kestena", dovodeći do njegovog potpunog sušenja. Pored vrsta roda Castanea ostali domaćini gljive C. parasitica pripadaju familijama: Aceraceae, Betulaceae, Fagaceae, Anacardiaceae, Juglandaceae i Magnoliaceae. Na vrstama ovih familija javlja se kao saprofit. Izuzetak, po nekim autorima predstavlja hrast, na kom se može javiti i parazitski. Porast micelije C. parasitica ispitivan je na podlogama napravljenim od kore: pitomog kestena (Castanea sativa), crnog jasena (Fraxinus ornus), javora (Acer pseudoplatanus), hrasta kitnjaka (Quercus petraea), tise (Taxus baccata), leske (Corylus avellana) sitnolisne lipe (Tilia cordata), mleča (Acer platanoides) i oraha (Juglans regia). Posle 28 dana podloga nije u potpunosti obrasla samo u varijantama kada je podlozi dodavana kora javora i mleča.

It is a well-known fact that a large number of parasitic and saprophytic fungi grow on sweet chestnut trees. However, the greatest damage is caused by C . parasitica which causes "sweet chestnut blight" and leads to its dieback. Hosts other than Castanea species include the following families: Aceraceae, Betulaceae, Fagaceae, Anacardiaceae, Juglandaceae i Magnoliaceae, where it grows as a saprophyte. The exception, according to some authors, is oak, where it can also occur as a parasite. Mycelial growth of C. parasitica was tested on media made of the bark of sweet chestnut (Castanea sativa), manna ash (Fraxinus ornus), sycamore maple (Acer pseudoplatanus), sessile oak (Quercus petraea), common yew (Taxus baccata), hazel (Corylus avellana), small-leaved linden (Tilia cordata), Norway maple (Acer platanoides) and English walnut (Juglans regia). After 28 days, the medium was not completely overgrown only in the variants with sycamore maple and Norway maple bark added to the medium.
