摘要
用2个浓度的尖孢镰刀菌毒素处理大豆胚根,来研究毒素对组织超微结构的影响。结果表明:毒素处理后,胚根细胞质壁分离;质膜、线粒体膜、核膜、液泡膜局部断裂;线粒体肿胀、变形、内部电子透明化、空泡化;细胞壁变形、断裂、有的细胞解体。损害发生最早的是线粒体和质膜。低浓度条件下,抗病品种比感病品种受害轻。
The effects of Fusarium oxysporium toxin on the ultrastructure of soybean radicle tissue were studied by electron microscopy. The radicle tissues were treated with toxin from F. oxysporium at two concentrations. The results showed that the damages to the radicle tissues of soybean included plasmolysis; disruption of membranes of plasma, mitochondria, nuclei and vacuoles; membrane of mitochondria swell and deformation, transparency of internal matrix and vacuolation; deformation and disruption of cell walls; disintegration of some cells.
