The early embryos after fertilization dissected from adult hermaphrodites normally hatched under hypergravity (200 G) or 3 D-clinorotation. On the other hand, the number of eggs laid by each hermaphrodite decreased and their hatching rate was reduced under hypergravity condition (100 G). The frequency of mitosis in the gonadal tips was also reduced. These indicate that the meiotic process and/or fertilization step and germline mitosis are more sensitive to hypergravity. It was also found that the first cleavage plane in the 1-cell embryo was slid to some extent by re-orientation of liquid culture vessel, but the pattern and timing of cleavages were not affected.","subitem_description_type":"Other"}]},"item_5_description_32":{"attribute_name":"資料番号","attribute_value_mlt":[{"subitem_description":"資料番号:
