| 摘 要： | 用褐藻酸降解菌对海带进行人为感染，经培养使其产生烂斑，通过组织显微切片观察表明：1、褐藻酸降解菌首先侵入内皮层，然后再逐渐侵入到外皮层、髓部和表皮，最终导致海带病烂。2．感染后内皮层伤害最重，其次是外皮层和髓部，表皮的伤害最轻。3、侵染海皮层的细胞中，有大量颗粒状储藏物质，其直径范围在1．5－4．0μm之间，平均直径为2．7μm。形状为椭圆或圆形。

| Abstract: | The changes of histology and cytology in Laminaria japonica were studied by art ificial infection and
microscopic observation. The results showed as follow s: 1. The endodermis was infected f irstly by alginic acid
decomposing bacteria ; the exodermis , pith and epidermis were infected later. 2. The damage of endodermis was
heaviest , exodermis and pith were damaged less heavily, and the effect of alginic acid decomposing bacteria on
epidermis was least remarkable. 3. a lot of storage material was accumulated in endodermic cells of infected
laminaria japonica compared with control; the diameter of storage particles was from 1. 5 Lm to 4. 0 Lm, and the
average value was 2. 7Lm. |
