Effect of P and Ca on the mycorrhiza of P. sylvestris formation in aseptic condition

Abstract

Ihe effect of some phosphorus and calcium compounds on mycorrhiza formation in pure cultures was investigated. In this experiment — Cenococcum groniforme, Suillus bovinus and Tricholoma albobrunneum were used. The ability to synthese acid phosphatase was tested in 11 strains. The presence of P has a stimulating effect on mycorrhiza formation by S. bovinus und T. albobrunneum. On control medium and medium containing CaO mycorrhiza was absent or only single. Ali strains synthetised phosphatase. The lowest enzymatic activity was found in two C. graniforme strains.
