Abstract
Response of in vitro wheat anther to Fusarium graminearum toxin was studied using induction medium containing Fusarium graminearum crude toxin.The results showed that the toxin had the hormonelike activity and promoted wheat anther tissue to differentiate and form anther callus in the low concentration.At the same time,the toxin had toxicity and affected differentiation of wheat anther and formation of anther callus in the high concentration.When the concentration of the toxin was higher than a certain degree,crude toxin had stronger toxicity with the increasing of the concentration.The abilities of wheat anther differentiation and forming callus fell down quickly and the effects existed in such aspects as reducing the response frequency of wheat anther and induction frequency of anther callus.In addition,the effect of crude toxin was different among variant genotype.In general,anthers from susceptible cultivars/hybrids were easier to be killed by lower toxin concentrations than those from cultivars/hybrids of less susceptible parents.
