Abstract:

Just at the beginning of the sixties in the course of the real ization of a major pine afforestation program the demand on mycorrhizal inoculum emerged from the side of forestries. Our first attempt to produce mycorrhizal inoculum, based on data taken from the literature, did not meet with success. As we saw it, thorough knowledge of the physiology of mycorrhizal fungi is needed for producing inoculum.

Some progress in producing inoculum has been made in the course of our investigations on mycorrhizal fungi, we have succeeded in producing inoculum and performing even the inoculation successfully. Because there are, however, quite a lot of delicious edible mushrooms among the mycorrhizal fungi, we have thought it worth continuing physiological examinations in the expectation of getting nearer to the solution of questions connected with the fruit body formation of fungi.

Although in the course of researches on mycorrhiza a great deal of matter of knowledge has accumulated – it is enough to refer to the works of Hartig, Frank, Kamenski, Stahl, Melin, Bjorkman, Moser, Lobanov and many others-, it is, however, still unsatisfactory that we know about the fruit body formation of these symbiont fungi. The recent results of KARPlNSKY (1961) as well as those of ZADRAZIL and his collaborators (1973) are well-known. Both research groups proved that it was possible to produce primordia forming of Boletus edulis and other mycorrhizal fungi in sterile culture. The unsolved problem is the further nutrition of these primordia in such a way that they would reach the fruit body size of mushrooms growing under natural conditions.

In our opinion our results – to be outlined as follows – will present some help to solve the problem of fruit body formation. I am going to give a brief account of the results of more than ten years’work, therefore the detailed description of the methods employed will be omitted and the stress will be laid on principal results and conclusions.
