Genes a and b are responsible not only for the reduced growth of many vegetative organs but also for reduction in number of tillers and roots and in fertility. But the growth of some organs such as root, floral organ (stamen and pistil), pollen, ligule mld auricle is not subject to the effect of them. It seems that both dwarf genes do not manifest their effects at the embryonal stage of life cycle. While the dwarfs are superior to normal in chlorophyll content and osmotic value of leaves, they have higher photosynthetic efficiency than normal. The relation between the amount of effective auxin in tissues and growth of organs may be summarized as follows: 1) The limitted growth of coleoptile and mesocotyl of the dwarfs is found to be due to the smaller number of cells and not to the inhibition of elongation of them, and this may be presumably caused by the lower level of auxin at the very early stage of germination. 2) This inferiority of dwarfs in auxin content is retained through the whole period of their growth. 3) At the same time we can conclude that there may be some destruction or inactivation of effective auxin in the tissues of dwarf coleoptile. 4) It appears that there is also a correlation between the amount of auxin and growth of young caryopsis at the early stage of grain formation. Concerning to the growth-responces of organs of dwarf plants to the treatment of growth-substances and nutritions we can find the following facts: 5) Maximal growth promotion by heteroauxin treatment of young seedling and embryo of dwarfs is obtained at higher concentrations than with normal; and the rate of increase in growth is also found to be greater in dwarfs. 6) From the results of culture experiments we can see that the dwarf plants are more promoted in growth than with normals by addition of growth substance but have less capacity to utilize the nutrient materials added simultaneously to them. 7) Addition of growth-substances to the nutrient solution appears to induce more effect on the number of roots and tillers rather than on the elongation of them. In conclusion we can say that one of the effects of dwarf genes is to control the production or activation and localization of growth-substance in plants and induce differential inhibition of growth of organs concerned. But we may realize that the manifestation of dwarf genes must be more complex and pleiotropic than to be understood by the known effects of growth substances as far.", "subitem_description_type": "Abstract"}]}, "item_10_description_30": {"attribute_name": "資源タイプ（コンテンツの種類）", "attribute_value_mlt": [{"subitem_description": "Article", "subitem_description_type": "Other"}]}, "item_10_description_31": {"attribute_name": "フォーマット：mimeタイプ", "attribute_value_mlt": [{"subitem_description": "application/pdf", "subitem_description_type": "Other"}]}, "item_10_description_5": {"attribute_name": "引用", "attribute_value_mlt": [{"subitem_description": "信州大學紀要 (4): 1-31(1953)", "subitem_description_type": "Other"}]}, "item_10_publisher_4": {"attribute_name": "出版者", "attribute_value_mlt": [{"subitem_publisher": "信州大学"}]}, "item_10_select_64": {"attribute_name": "著者版フラグ", "attribute_value_mlt": [{"subitem_select_item": "publisher"}]}, "item_10_source_id_40": {"attribute_name": "書誌レコードID", "attribute_value_mlt": [{"subitem_source_identifier": "AN00411443", "subitem_source_identifier_type": "NCID"}]}, "item_10_text_66": {"attribute_name": "sortkey", "attribute_value_mlt": [{"subitem_text_value": "01"}]}, "item_1627890569677": {"attribute_name": "出版タイプ", "attribute_value_mlt": [{"subitem_version_resource": "http://purl.org/coar/version/c_970fb48d4fbd8a85", "subitem_version_type": "VoR"}]}, "item_creator": {"attribute_name": "著者", "attribute_type": "creator", "attribute_value_mlt": [{"creatorNames": [{"creatorName": "中山,  包"}], "nameIdentifiers": [{"nameIdentifier": "49015", "nameIdentifierScheme": "WEKO"}]}]}, "item_files": {"attribute_name": "ファイル情報", "attribute_type": "file", "attribute_value_mlt": [{"accessrole": "open_date", "date": [{"dateType": "Available", "dateValue": "2015-09-28"}], "displaytype": "detail", "download_preview_message": "", "file_order": 0, "filename": "Shinshu_Bulletin04-01.pdf", "filesize": [{"value": "3.4 MB"}], "format": "application/pdf", "future_date_message": "", "is_thumbnail": false, "licensetype": "license_note", "mimetype": "application/pdf", "size": 3400000.0, "url": {"label": "Shinshu_Bulletin04-01.pdf", "url": "https://soar-ir.repo.nii.ac.jp/record/17194/files/Shinshu_Bulletin04-01.pdf"}, "version_id": "a9fe1f03-6d33-46a6-b169-b90f869a7f6f"}]}, "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", "resourceuri": "http://purl.org/coar/resource_type/c_6501"}]}, "item_title": "稲の矮性の発現に関する遺伝生理学的研究", "item_titles": {"attribute_name": "タイトル", "attribute_value_mlt": [{"subitem_title": "稲の矮性の発現に関する遺伝生理学的研究", "subitem_title_language": "ja"}, {"subitem_title": "GENETICO-PHYSIOLOGICAL STUDIES ON THE DEVELOPMENT OF DWARFISM IN RICE PLANT", "subitem_title_language": "en"}]}, "item_type_id": "10", "owner": "1", "path": ["1675"], "permalink_uri": "http://hdl.handle.net/10091/4659", "pubdate": {"attribute_name": "PubDate", "attribute_value": "2010-02-12"}, "publish_date": "2010-02-12", "publish_status": "0", "recid": "17194", "relation": {}, "relation_version_is_last": true, "title": ["稲の矮性の発現に関する遺伝生理学的研究"], "weko_shared_id": -1}
