To investigate the non-genetical variation of characters of plants belonging to the genus Coix, the present writer cultured Hatomugi (Coix Ma-yuen Roman.), Juzudama (Coix Lacryma-Jobi L.) and F_5 strains bred with view to tallness in mix planting with three kinds of distance between each plant (30,60 and 90cm) and considered the variation of characters due to these conditions. Generally plant height, number of tillers and dry matter weight vary very much with the density of planting. That is to say, plant height increases considerably with dense planting while number of tillers and dry matter weight decreases remarkably. The variation of these characters due to density of planting changes its aspect again with mix planting and difference of kind of mixed plant have influence on the effect. Meanwhile the effect of mix planting is not so great as the effect of density. Interspecific difference of characters can not be clearly recognized in mix planting field, but generally speaking, short culm species are liable to be influenced by tall species. Though dry matter weight decreases by dense planting, harvest becomes larger as number of cultured plant increases remarkably. So the most effective method to high yield is to increase number of plant by means of comparatively dense planting. But before settling this matter, we must analyze the change of chemical composition of feed due to the change of characters and determine the best method of cultivation to enrich the com ponent useful as fodder crop.","subitem_description_language":"en","subitem_description_type":"Other"}]},"item_3_source_id_1":{"attribute_name":"雑誌書誌ID","attribute_value_mlt":[{"subitem_source_identifier":"AN00062275","subitem_source_identifier_type":"NCID"}]},"item_3_source_id_20":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"00757373","subitem_source_identifier_type":"PISSN"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorAffiliations":[{"affiliationNameIdentifiers":[],"affiliationNames":[{"affiliationName":""}]}],"creatorNames":[{"creatorName":"村上, 道夫","creatorNameLang":"ja"},{"creatorName":"ムラカミ, ミチオ","creatorNameLang":"ja-Kana"},{"creatorName":"Murakami, Michio","creatorNameLang":"en"}],"familyNames":[{},{},{}],"givenNames":[{},{},{}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"藤原, 宏志","creatorNameLang":"ja"},{"creatorName":"フジワラ, ヒロシ","creatorNameLang":"ja-Kana"},{"creatorName":"Fujiwara, Hiroshi","creatorNameLang":"en"}],"familyNames":[{},{},{}],"givenNames":[{},{},{}],"nameIdentifiers":[{}]},{"creatorAffiliations":[{"affiliationNameIdentifiers":[],"affiliationNames":[{"affiliationName":""}]}],"creatorNames":[{"creatorName":"原田, 賢之","creatorNameLang":"ja"},{"creatorName":"ハラダ, ケンシ","creatorNameLang":"ja-Kana"},{"creatorName":"Harada, Kenshi","creatorNameLang":"en"}],"familyNames":[{},{},{}],"givenNames":[{},{},{}],"nameIdentifiers":[{}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2017-02-20"}],"displaytype":"detail","filename":"KJ00000078769.pdf","filesize":[{"value":"1.1 MB"}],"format":"application/pdf","mimetype":"application/pdf","url":{"label":"KJ00000078769.pdf","url":"https://kpu.repo.nii.ac.jp/record/4770/files/KJ00000078769.pdf"},"version_id":"2ec30d82-b38f-4e2a-a820-a170a393260a"}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"jpn"}]},"item_resource_type":{"attribute_name":"資源タイプ","attribute_value_mlt":[{"resourcetype":"departmental bulletin paper"}]},"item_title":"Coix 属の改良に関する育種学的研究 XI : 栽植密度および混植によって生起する競合効果(農学部門)","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Coix 属の改良に関する育種学的研究 XI : 栽植密度および混植によって生起する競合効果(農学部門)","subitem_title_language":"ja"}]},"item_type_id":"3","owner":"14","path":["409"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2017-02-20"},"publish_date":"2017-02-20","publish_status":"0","recid":"4770","relation_version_is_last":true,"title":["Coix 属の改良に関する育種学的研究 XI : 栽植密度および混植によって生起する競合効果(農学部門)"],"weko_creator_id":"14","weko_shared_id":-1},"updated":"2024-05-08T04:49:54.002003+00:00"}
