ASPECTS REGARDING THE IDENTIFICATION OF THE MICROFLORA PRESENT ON FOREST SEEDS INTENDED FOR SOWING IN SPRING 2022

Forest crops (nurseries and plantations) impose difficulties on foresters, the main cause being disturbing or harmful factors that compete and interact in different directions, but whose result is the weakening of seedlings, culminating in their death. Given that the number of seedlings in nurseries and plantations is high compared to the unit area, the risk of disease and pest attacks is very high. For this reason, it is necessary to monitor the annual forest crops, both in terms of biological material and soil, in order to control or eliminate possible sources of infestation. In order to achieve the proposed objectives, ash, maple and lime seeds were harvested from Mihai Viteazu Nursery, spruce seeds from Voivodeni Nursery, Forest district Someșu Rece, Forest district Beliș and larch from Forest district Beliș. Specific phytopathological analyzes of the seed samples were performed on the seeds in order to accurately determine the possible pathogens. In the analyzes, the pathogens Fusarium oxysporum, Alternaria alternata and Botrytis cinerea were identified on both deciduous and coniferous seeds.
