采用透射电子显微镜观察经10℃低温处理2d的豌豆下胚轴细胞超微结构的结果显示,10℃低温处理后,豌豆下胚轴细胞超微结构未受到显著伤害,但其一些抵御寒冷的适应性能力有变化。质膜呈波浪状,或质壁分离,或凹陷、外凸形成小泡;中央大液泡和细胞质内、以及内质网和高尔基体附近多处出现泡状结构或小泡;多数质体变形为哑铃形、变形虫形、马蹄形、镰刀形和棒状等,其中的淀粉粒显著减少。
Transmission electron microscopy was used to observe the ultrastructure of hypocotyl cells of pea under 2 ℃ for 10 days. The ultrastructure of hypocotyls of pea was not significantly damaged after 10 ℃ treatment, but some of them were resistant to cold adaptation Sexual ability has changed. The plasma membrane was wavy, or plasmolysis, or depression, protruding to form vesicles; central vacuole and cytoplasm, and the endoplasmic reticulum and Golgi near the bubble-shaped structures or vesicles occur at many places; the majority of plastid deformation Dumbbell, amoeba, horseshoe, sickle and stick, etc., in which the starch grains are significantly reduced.
