Studies on Resistance of Wheat Varieties to Scab (Gidderella zeae (Schw.) Petch.) : II. Inoculation onto leaf blade of the water-cultured plants pulled out from the field.

摘要

The method of scab inoculation onto leaf blade, reported previously, is inconvenient to treat in the field. It will be more favorable if the scab can be inoculated onto leaf blade of the plants water-cultured after being pulled out from the field. The rerults of this study indicated that this was possible. The plants were pulled out from the field and water -cultured in the beaker. After having been inoculated, they were kept at room temperature (15∼20°C) during daytime and at 25°C in the thermostat at night. Scab infection was observed within several days. It must be mentioned that when the plants were at heading time, all the head should be removed to prevent emaciation of the treated leaves.
