Abstract

An efficient incubation and inoculation system for white rust was established using plantlets of chrysanthemum growing in vitro. The internal conditions of a culture vessel (plant box) were maintained at a humidity of 90-100% and an optimum temperature of 20-25 degreesC, which are suitable conditions to germinate teliospores and basidiospores of the pathogen. Telia were maintained continuously on plants in the plant bos and were used as an inoculum for infection experiments throughout the gear, allowing differences in susceptibility to white rust among chrysanthemum cultivars to be detected. Susceptibility to white rust in the plant-box evaluation showed a good correlation with the rating of sporulation on plants grown in a greenhouse. Themethod described here is a simple, space-saving inoculation system to evaluate the susceptibility of chrysanthemums to white rust.
