PINI INFLUENCE OF THE SOURCES OF CARBON AND NITROGEN ON MORPHOLOGICAL PATHOGENIC CHARACTERISTICS OF FUSARIUM OXYSPORUM VAR. ORTHOCERAS F. PINI sr Fungus Fusarium oxysporum S c h l e c h t, emend. S n y d e r et H a n s var. orthoceras (App. et W r.) B i l a i comb. nova f. pini, isolated from lain down saplings of black pine and grown ,,in vitro" on different sources of carbon and nitrogen, has preserved its basic morphological characteristics, providing in that way the continuity of the existance. It has shown on all nutritive substances which were used in the experiment, its pathogenic characteristics - embryo decay and lying down of the saplings. Therefore it can be concluded that this fungus, being a wery stable and agressive organism, represents an important danger for black pine seedlings in the nurseries. 2025-03-10T12:42:08.573Z 44 yes 46 Vera Plavšić application/pdf 4244872 https://unilib.phaidrabg.rs/o:7233 no yes 1 70 92000001 1983 71A07 Zbornik radova Instituta za šumarstvo 20-21 59 70 Institut za šumarstvo 1983
