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、浸染海带内皮层的细胞中 ,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。
The changes of histology and cytology in Laminaria japonica were studied by artificial infection and microscopic observation.The results showed as follows:1.The endodermis was infected firstly 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 μm to 4.0 μm, and the average value was 2.7 μm.
