Abstract

We tried to apply the onion epidermal strip method for the observation of conidial germination, hyphal elongation and hyphal penetration of Botrytris cinerea. The behavior of the fungus on the strip was compared with that on a petal of Primula polyantha, the natural host plant. The similar tendency was observed on the conidial germination and hyphal penetration on both system. In addition, each stage on the onion epidermal strip was markedly accelerated by the addition of 1 to 2% fructose to the conidial suspension. It was suggested that the onion epidermal strip method might be applicable for assaying the effect of chemicals on B. cinerea.
