Effect of rhizosphere fungi on seed germination

Abstract

The effect of culture filtrates of some common rhizosphere fungi on the seed germination of Dichanthium annulatum, Bothriochloa pertusa and Setaria glauca was studied. Surface sterilized seeds were soaked in the fungal culture filtrates for 24 hours and after several washings in distilled water transferred to moist filter paper in Petri dishes and the percentage germination recorded. No significant inhibition or stimulation of germination was noticed in any of the treatments. The only exception was Trichoderma viride which inhibited the germination of D. annulatum seeds to some extent. © 1969 Martinus Nijhoff.
