Effect of different concentrations of actinomycin D applied 1 h prior to inoculation on the susceptibility of pea endocarp tissue to the true pathogen, Fusarium solani f. sp. pisi (Fspi). The resistance responses of pea endocarp tissue against a pea pathogen (Fspi) are sharply influenced by different concentrations of actinomycin D applied 1 h prior to inoculation. Concentrations in photos are as follows: A = H2O; B = 1 μg/ml; and C = 3 μg/ml. Arrows indicate the inoculated spore. Bar = 50 microns.
