Effect of the Toxic Culture Filtrate of the Fungus Stemphylium botryosum on the Growth of Some Fungi and on the Germination of Some Plant Seeds
Abstract
Results of study the effect of culture filterate of Stemphylium botryosum on the germination percentage of barley, Lentil, wheat and chichpea seeds (in vitro), showed significant inhibition on germination which reached 100% in chichpea seeds.
As for plumule and radical lengths, the results indicated different degrees of inhibition ,minimum of which was the lentil seeds. The effect of different concentrations (2.5, 5, 10, 20 %) of the filterate on the growth of some fungi (Cladosporinm herbarum, Aspergillus flavus, Fusarinm oxysproum, Macrophomina phaseolina) was demonstrated by the 20% concentration as it caused inhibitions in the growth of M. phaseolina and F. oxysproum 11% and 33% respectively. While the other concentration had no inhibitory effect on the fungi.
