peridium

Type genus of Geastraceae ; fungi whose outer peridium when dry splits into starlike segments .

地星属的模式属；真菌的包被当干裂时分裂成像星星一样的部分。

Any fungus of the family Geastraceae ; in form suggesting a puffball whose outer peridium splits into the shape of a star .

g家族的任何一种菌类；外形上象马勃菌，其外部的包被分裂成星状。

When the fruit ripens the starch content of green peridium is gradually decreased until it disappears at all .

当胚成熟时，绿果皮的淀粉逐渐减少，直至全部消失。

After fertilization , with the growth of the proembryo in the green peridium the starch accumulates again , with which ceils are filled , the starch content is at a second maximum .

受精作用之后，绿果皮随幼果的发育再次积累淀粉，形成第二次高峰。

Meiosis , which occurs only in the formation of gametes , is a specialized form of cell division . type genus of Geastraceae ; fungi whose outer peridium when dry splits into starlike segments .

仅仅发生在配子形成中的减数分裂是一种特殊形式的有丝分裂。地星属的模式属；真菌的包被当干裂时分裂成像星星一样的部分。

A method for the determination of ricin by double antibody sandwich enzyme-linked immunosorbent assay was developed , the experiment conditions , including ricin polyclonal antibody peridium concentration and method , ricin monoclonal antibody working concentration , second enzyme labelling antibody and developing time were optimized .
