Armillaria Mellea

Ovo istraživanje namijenjeno je određivanju prosječnog kemijskog sastava, udjela bioaktivnih spojeva i antioksidacijske aktivnosti jestivih samoniklih gljiva Albarellus per-caprae i Armilaria mellea. Rezultati određivanja kemijskog sastava su pokazali da su gljive bogat izvor bjelančevina i ugljikohidrata te da imaju male količine masti, a dobar su izvor energije. Koncentracije pet bioaktivnih spojeva (askorbinska kiselina, β-karoten, likopen, ukupni fenoli i flavonoidi) određene su ekstrakcijom plodišta gljiva u vrućoj vodi i metanolu. Tri komplementarna kemijska ispitivanja; reducirajuća snaga, uklanjanje slobodnih radikala (DPPH) i sposobnost keliranja iona željeza korišteni su za određivanje antioksidacijskih svojstava ekstrakata. Najveće vrijednosti antioksidacijskog kapaciteta određene su u ekstraktima A. mellea s vrućom vodom (9,01 μM TE/g s.tv. u reducirajućoj snazi, 65% u sposobnosti uklanjanja slobodnih radikala, i 85% u sposobnosti keliranja). Vrijednosti EC50 za tri različita ispitivanja antioksidanta bile su između 1,63 mg/ mL i 6,86 mg/mL. Zbog ovih karakteristika, jestive samonikle gljive A. per-caprae i A. mellea mogu biti dio dobro uravnotežene prehrane i izvor bioaktivnih sastojaka.

Armillaria Mellea

The zone of antagonism, known as the "black line," that occurred between the confronting margins of diploid isolates of different Armillaria mellea complex species was enhanced by incubation in L-β-3,4-dihydroxyphenylalanine (L-DOPA). Intraspecific crosses and crosses of genetically identical isolates did not produce a black line after similar treatment with L-DOPA.

An investigation of decay in western hemlock (Tsuga heterophylla (Raf.) Sarg.) and fir (mainly Abies amabilis (Loud.) Forb.) in the Juan de Fuca forest region of British Columbia has shown that the major organisms causing root and butt rots are the same in both species. These are Poria subacida (Peck) Sacc., Fomes annosus (Fr.) Cke., Armillaria mellea Vahl ex Fr., Polyporus sulphureus Bull. ex Fr., and P. circinatus Fr. Those organisms causing trunk rots of western hemlock, in decreasing order of importance, are Fomes pinicola (Sw.) Cke., F. Pini (Thore) Lloyd, Stereum abietinum Pers., Fomes Hartigii (Allesch.) Sacc. and Trav., and Hydnum sp. (H. abietis). These same organisms causing trunk rots of fir, in decreasing order of importance, are Fomes pinicola, Stereum abietinum, Hydnum sp. (H. abietis), Fomes Pini, and Fomes Hartigii. The logs of 963 western hemlock were analyzed in detail. Maximum periodic volume increment was reached between 225 and 275 years of age. Maximum periodic volume increment was reached between 275 and 325 years of age in the 719 fir that were analyzed. Scars were the most frequent avenue of entrance for infection. In 59% of the cases of infection studied the fungus had entered through wounds.
