Influence of mineral salts upon activity of Trichoderma harzianum non-volatile metabolites on Armillaria spp. rhizomorphs
Copyright policy )Influence of mineral salts upon activity of Trichoderma harzianum non-volatile metabolites on Armillaria spp. rhizomorphs
Effect of non-volatile metabolites of Trichoderma harzianum together with certain salts containing Mg<sup>++</sup>, Fe<sup>+++</sup>, Mn<sup>++</sup>, Cu<sup>++</sup>, Al<sup>+++</sup>, Ca<sup>++</sup>, K<sup>++</sup>, Na<sup>+</sup>, PO<sub>4</sub><sup>---</sup> and SO<sub>3</sub><sup>---</sup> on the production and length of rhizomorphs of <em>Armillaria borealis</em>, <em>A. gallica</em> and <em>A. ostoyae</em> was studied. In pure medium, <em>T. harzianum</em> exhibited stimulating effect on rhizomorphs of <em>A. borealis</em> (both number and length) and <em>A. ostoyae</em> (only initiation). Cu<sup>++</sup> salt totaly inhibited the initiation of rhizomorphs of <em>Armillaria borealis</em>, <em>A. gallica</em> and <em>A. ostoyae</em>. Effect of other compounds on the activity of <em>T. harzianum</em> depended on <em>Armillaria</em> species. The majority of chemical compounds tested supressed the activity of non-volatile metabolites of <em>T. harzianum</em>. Evident stimulating effect was observed under influence of sulphate salts consisting Al<sup>++</sup> and Fe<sup>+++</sup> on the rhizomorph number of <em>A. borealis</em> and <em>A. gallica</em>, respectively.
