| 摘 要： | 研究了在离体培养条件下,大麦耐、感赤霉病基因型花药对赤霉病菌粗毒素的反应。结果表明:随着赤霉病菌粗毒素预处理浓度的提高,大麦花药愈伤组织诱导率降低,愈伤组织的绿苗分化率降低。耐病基因型的愈伤组织诱导率和绿苗分化率的降低幅度均小于感病材料。说明大麦个体水平的耐、感赤霉病性与花药水平对赤霉病粗毒素反应具有一致性。

| Abstract: | Response of barley anthers of 3 genotypes with higher tolerance and 1 genotype with susceptibility in vitro culture and callus derived to crude toxin of Fusarium graminearum was investigated. The results showed that with the increase of the concentration of the crude toxin in culture media, the frequency of callus induction and green plant regeneration was decreased. Comparing the two genotypes, the frequency of callus induction and green plant regeneration was less affected for tolerance-genotype. So a conclusion can be made that anther tolerance or susceptibility to Fusarium graminearum toxin is correlated with barley genotype. |
