1. 原種8品種, 現行指定交雑種2品種の体長, 体幅を測定し, これらの相互関係を解析した結果, 蚕の成長に伴う体長, 体幅の推移は蚕品種によって差が認められたが, いわゆる日本種, 支那種など地域種による一定の傾向は, 見出すことはできなかった。
2. 蚕が正常に成長する範囲における飼育最大密度は, 蚕座面積に対する蚕体平面積の占める割合で定まり, その値は全齢を通じて一定であると仮定した。そして, 実験値から1～4齢の眠蚕および5齢の盛蚕において「体長×体幅」で蚕座面積に占める割合を71.5%と算出した。この密度は現行交雑種の普通育において, おおむね蚕座0.1m2あたり, 1齢12,200頭, 2齢3,200頭, 3齢1,250頭, 4齢400頭, 5齢110頭であった。
3. 上記の仮定に基づいて推定された飼育密度について, 支131号×日131号および支131号を供試して飼育試験を行なった結果, 各計量的形質に及ぼす悪影響は認められず, この仮定は本試験の範囲では肯定することができた。"}],"abstractLicenseFlag":"disallow"}],"creator":[{"@id":"https://cir.nii.ac.jp/crid/1410572172118327681","@type":"Researcher","personIdentifier":[{"@type":"NRID","@value":"9000254389855"}],"foaf:name":[{"@language":"en","@value":"UEDA Satoru"},{"@language":"ja","@value":"上田 悟"}],"jpcoar:affiliationName":[{"@language":"ja","@value":"農林省蚕糸試験場養蚕部"}]},{"@id":"https://cir.nii.ac.jp/crid/1410572172118327680","@type":"Researcher","personIdentifier":[{"@type":"NRID","@value":"9000254389856"}],"foaf:name":[{"@language":"en","@value":"SUZUKI Kiyoshi"},{"@language":"ja","@value":"鈴木 清"}],"jpcoar:affiliationName":[{"@language":"ja","@value":"農林省蚕糸試験場養蚕部"}]}],"publication":{"publicationIdentifier":[{"@type":"PISSN","@value":"00372455"},{"@type":"EISSN","@value":"1884796X"},{"@type":"NDL_BIB_ID","@value":"000000018460"},{"@type":"ISSN","@value":"00372455"},{"@type":"LISSN","@value":"00372455"},{"@type":"NCID","@value":"AN00190300"}],"prism:publicationName":[{"@language":"en","@value":"The Journal of Sericultural Science of Japan"},{"@language":"ja","@value":"日本蚕糸学雑誌"},{"@language":"en","@value":"J.
