Research Concerning the Influence of Inducing of some Mycorrhizal Substrates on Stimulating the Sprout, Growth and Development of Quercinae Seedlings

摘要

The health of the forest seedlings can be translated also through growth vigor, and this directly affects the quality of stands regeneration and the production costs of the afforestation material. Mycorrhiza is a symbiotic association (mycorrhizal association), of bio system type, mutually beneficial (bilateral positive), made up of the mycelium of a fungus and the roots of herbaceous or woody plants. In trees, the relationship between the fungus and the plant is particularly important; many woody species cannot exist in the absence of mycorrhiza. The aim of the research is to find effective methods of inducing and stimulating ecto mycorrhiza in forestry nurseries and to determine their influence on biometric features of the oak seedlings, growth vigor and health status, in the early years of life, respectively.
