油松茎端的皮层薄壁组织和幼茎木薄壁组织中具含树脂细胞分布。在光学显微镜下观察，硫酸奈尔兰染色的切片，发现树脂滴分布于细胞质中；在电子显微镜下观察锇酸染色切片，发现树脂滴分布于细胞的线粒体、高尔基体、内质网、核膜和小液泡中，同时也分布于质膜两边。从形态演化分析含树脂细胞在树脂分泌结构中属原始类型，由它演化为树脂道
Pinus taiwanensis cortex parenchyma and young stem parenchyma tissue containing resinous cell distribution. Observed under a light microscope, the sections stained with Nener’s sulfate showed that the resin droplets were distributed in the cytoplasm. The sections of the osmium tetroxide staining were observed under an electron microscope and the resin droplets were distributed in the mitochondria, Golgi, endoplasmic reticulum and nuclear membrane And small vacuoles, but also distributed on both sides of the plasma membrane. From the morphological analysis of resin-containing cells in the resin secretion structure is the original type, which evolved into the resin road
