Testing of megagametophytes of some conifer species for defense reactions to the fungus Phaeolus schweinitzii

J. Hřib, B. Vooková

Abstract


The megametophytes of Picea abies, Pinus sylvestris, Pinus mugo and Larix decidua were cultured on modified solid agar MS medium with 5 mg.l-1 α-naphthaleneacetic acid and 0.1 mg.l-1 6-benzylaminopurine and exposed to a tester, the basidio-mycete Phaeolus schweinitzii. The megagametophytes of all tested species showed defense reactions manifested by inhibition of mycelial growth. The weakest defense reactions were shown by the megagametophytes of Picea abies and Larix decidua. The strongest defense reactions were found in Pinus sylvestris and Pinus mugo megagametophytes.
