油松含树脂细胞组织化学和细胞化学研究

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狐染色切片，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。

HISTOCHEMISTRY AND CYTOCHEMISTRY OF RESIN -CONTAINING CELL IN PINUS TABULAEFORMIS

Some resin containing cells are present in parenchym of cortex in shoot apex and xylem parenchym of stem in Pinus tabulaeformis .With the aid of microscope it is found that some globular droplets are stained into blue with Nile blue in resin containing cells.Under electron microscope osmiophilic droplets are found to occur in the mitochondria,Golgi bodies,endoplasmic reticulum,nuclear envelope and small vesicles,also on the both sides of plasmalemma in the resin containing cells.According to evolutionary trends the resin containing cells are primitive type,from them the resin ducts with conspicuous secretory structures are derived.
