Ultrastructural changes in barley aleurone, cells treated with gibberellic acid (GA3) for 24-36 hr are described. Many large vacuoles are seen in the ground cytoplasm; the coalasce to form one large central vacuole. Evidence is presented indicating that the vacuoles are formed from the aleurone grains. The dictyosomes of aleurone cells treated with GA3 for 24 hr or longer proliferate many vesicles. This proliferation of dictyosome vesicles is associated with the phase of rapid ribonuclease release from the aleurone cell. Estimates indicate that microbodies are considerably reduced in number with GA3 treatment from 24-36, hr while the number of mitochondria is not substantially affected relative to controls. P-Protein-like material is seen in the cytoplasm of these cells often in close proximity to endoplasmic reticulum and spiny vesicles.
用赤霉素（GA3）处理 24-36 小时的大麦糊粉层细胞的超微结构变化描述如下。在细胞质基质中可以看到许多大液泡；这些液泡合并形成一个大的中央液泡。有证据表明，这些液泡是由糊粉粒形成的。用 GA3 处理 24 小时或更长时间的糊粉层细胞的高尔基体复合体增殖了许多小泡。这种高尔基体小泡的增殖与核糖核酸酶从糊粉层细胞快速释放的阶段有关。研究表明，用 GA3 处理 24-36 小时后，微体的数量明显减少，而与对照相比，线粒体的数量没有实质性的变化。在这些细胞的细胞质中可以看到类似于 P-蛋白的物质，通常与内质网和刺状小泡密切相关。
