Chromosome number of somatic cell was 2n=22,and ten pairs were m-types, centromere located at median region, and one pair was sm-type, centromere located at submedian region. 2. The smallest pair had specific structure shown at proximal region near centromere. This region shown was weakly stained or partially stained by the Feulgen method. In this region, there were a few small dots at prophase and early metaphase, and one stained dot at late metaphase and meta-anaphase. The region couldn't be distinguished from the centromere clearly. 3. The proximal region of the smallest pair was stained darker than others by using the modificated Ag-I method. It was recognized that nucleolar organizing region (NOR) was located at this region. Number of nucleolus at resting stage was two at the maximum, and corresponded to the number of NOR.","subitem_description_type":"Other"},{"subitem_description":"紀要論文","subitem_description_type":"Other"}]},"item_1617186643794":{"attribute_name":"Publisher","attribute_value_mlt":[{"subitem_1522300295150":"ja","subitem_1522300316516":"琉球大学農学部"}]},"item_1617186702042":{"attribute_name":"Language","attribute_value_mlt":[{"subitem_1551255818386":"jpn"}]},"item_1617186783814":{"attribute_name":"Identifier","attribute_value_mlt":[{"subitem_identifier_type":"HDL","subitem_identifier_uri":"http://hdl.handle.net/20.500.12000/4014"}]},"item_1617186920753":{"attribute_name":"Source Identifier","attribute_value_mlt":[{"subitem_1522646500366":"ISSN","subitem_1522646572813":"0370-4246"},{"subitem_1522646500366":"NCID","subitem_1522646572813":"AN00250548"}]},"item_1617186941041":{"attribute_name":"Source Title","attribute_value_mlt":[{"subitem_1522650068558":"ja","subitem_1522650091861":"琉球大学農学部学術報告"},{"subitem_1522650068558":"en","subitem_1522650091861":"The Science Bulletin of the Faculty of Agriculture.
