| 摘 要： | 将指形管装的粟锈菌夏孢子和纸袋装的病叶保存在冰箱中,10个月后夏孢子仍有一定的发芽率,用其接种谷子可引起发病。随着保存时间的推移,夏孢子的发芽率及其接种发病程度也降低。寄主范围试验表明,该菌可侵染狗尾草属中的几种狗尾草,但不侵染金色狗尾草。

| Abstract: | The urediospores of the millet rust fungus in small glass tube and the rusted leaves in paper envelopes were stored in the refrigerator. On 10 months or more the better part of the urediospores can germinate and may infect the millet. As time goes on the germination percentage and the infection instensity of the urediospores have changed on the decrease. The tests of the host range showed that urediospores infect more than one species of Setaria but there was no evidence of any infection on Setaria glauca (L.) Beauv. |
