CONTRIBUTION TO THE STUDY OF PRUNOIDAE DIEBACK (INFLUENCE OF PATHOGENIC FUNGI)
In our Institute we are studying the influence of the pathogenic fungi on the dieback of this fruit trees.
In literature we find citations about the fact, that apricot cultures attacked by apoplexy show a damage in the main parts of conducting tissues. Jirák5, Dvorák3, Luxova7, Erdelska4 et al., who studied the diseases and the dieback, stated besides gummification and wilting, also stopping the activity of the cambium, browning, necroses of the bark and of the bast. In this work we wanted to cause similar symptoms by fungi on cultures of stone trees in orchards as well as to cause a reproduction of some changes under laboratory conditions.
