摘要
不同抗性品种的小麦种子，置于赤霉病病麦粒浸出液（毒液）中萌动发芽，结果不同抗性品种种子对毒液的敏感程度差异明显，抗病品种耐毒力强，种子萌动露白多，感病品种耐毒力差，种子萌动露白少。结果反映的抗性趋势与多年多点的田间抗病性鉴定资料相吻合。
Seeds of eight wheat varieties with different scab-resistances were soaked in the extracting so-lution from diseased grains of wheat scab(poison solution)for germination. the results showed that the susceptibilities of wheat seeds to the scab poison solution varied significantly with different varieties. The resitant varieties have strong standing capacity in the poison solution and show a high germinating rate;whreas,the sensitive varieties show low germinating rate.The above results are identical to the identify-ing data on the scab resistances of different wheat varieties from multi-site field test for years.
