. Annals of applied biology. Biology, Economic; Biochemistry. Ethel M. Doidge 63 Pathological Histology. Infection usually takes place through the nectaries, but the organism sometimes finds its way into the green tissues of the flower and flower stalks through the stomata. The rods multiply very rapidly in the intercellular spaces, and it is very noticeable that wherever the intercellular spaces are invaded, the contents of the adjacent cells become plasmolysed and stain very deeply with carbol fuchsin. In sections stained with carbol fiichsin and liaht green these showed up in startling contrast to the normal cells which stained light green and in some of which the nucleus could be plainly seen (Fig. 2).. Fig. 2. .Section through diseased receptacle, natural infection, drawn with Edinger's projection apparatus. An early stage of infection. After the cells are plasmolysed and killed they disintegrate very rapidly and collapse, the original cell outline completely disappears and the diseased area consists of a disorganised mass staining intensely with carbol fuchsin. When the receptacle is infected the flowers soon fall, but in some cases not until the infection has spread into the more deep-seated tissues of the ovary, all of which become blackened and disorganised (Fig. 3)..
