在小麦根腐病菌毒素作用下,叶片细胞超微结构均发生变化。线粒体和叶绿体受破坏的程度与毒素浓度和处理时间呈正相关。线粒体比叶绿体对毒素更为敏感。在同样处理条件下,抗根腐病小麦突变系 RB400叶细胞超显微结构的变化比其亲本小。
Under the action of Toxin of wheat root rot, the ultrastructure of leaf cells changed. The degree of destruction of mitochondria and chloroplast was positively correlated with the concentration of toxin and the treatment time. Mitochondria are more sensitive to toxins than chloroplasts. Under the same treatment conditions, the ultrastructural changes of the leaves of resistant mutant RB400 were less than that of their parents.
