| Abstract: | In coculture studies there is an interest in the relationships between phytoinoculs and fungi or bacteria. Apart from the manifestations described by parasitism, a particular importance – both theoretical and practical – is given to the symbiosis and saprophytism relations. Spontaneous infections are detrimental, while artificially produced cocultures represent modern study subjects. The phenomenon of coculture, produced spontaneously in the Drosera vitrocultures that we conceived, with a black-grey coloured fungus (which we have not been able to identify yet), led to the formation in the vicinity of the Drosera minirosettes colony, of an fungus with a crateriform body fruiting, of larger size than the actual Drosera culture. This phenomenon, quite spectacular from a biological point of view, is to be studied in various experimental conditions. We should mention that the culture media was favourable to the phytoinoculs (basis, Murashige – Skoog, 1962), being devoid of growth regulators. |
