Pollen tubes reached the basal end of the style by 48 hr in self-pollination of 'Georgia' and cross-pollination of 'Georgia'×'Hinomoto' by CSP. Using the pre-pollination technique in CSP enhanced the growth of pollen tubes both in self- and cross-pollination.\\r\\\\n2. Generative cell division of pollen tubes in the style was observed 24hr after pollination. In cross-pollination by SP, 78% of the pollen tubes had 2 sperm nuclei and 1 vegetative nucleus ('2S+V'), while only 15% of these appeared in the self-combination. Using CSP, pollen tubes with '2S+V' were 32%in cross- and 9%in self-pollination. The percentages increased to 54% and 35%, respectively, when pollen of 'Hinomoto' was used in the pre-pollination treatment.\\r\\\\n3. In SP, numerous pollen tubes which penetrated the style grew in a bunch between two rows of ovules in an ovary ; only a few pollen tubes reached the ovules near the mid-region.\\r\\\\n4. Penetration of pollen tubes to the micropyle occurred in about 35% of the ovules in cross-pollination by SP and in less than 10% of these by CSP. Pre-pollination in CSP effectively increased the percentage of ovules with a pollen tube in the micropyle.\\r\\\\n5. Only 3 full-seeds per capsule in self- and 6 in cross-pollination were obtained by CSP, whereas 11 and 23 seeds per capsule, respectively, were obtained as the result of pre-pollination.","subitem_description_type":"Abstract"}]},"item_5_full_name_3":{"attribute_name":"著者別名","attribute_value_mlt":[{"nameIdentifiers":[{"nameIdentifier":"39108","nameIdentifierScheme":"WEKO"}],"names":[{"name":"Li, Tong Hua"}]},{"nameIdentifiers":[{"nameIdentifier":"39109","nameIdentifierScheme":"WEKO"}],"names":[{"name":"Niimi, Yoshiji"}]},{"nameIdentifiers":[{"nameIdentifier":"39110","nameIdentifierScheme":"WEKO"}],"names":[{"name":"Nakano, Masaru"}]}]},"item_5_publisher_7":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"園芸学会"}]},"item_5_rights_15":{"attribute_name":"権利","attribute_value_mlt":[{"subitem_rights":"園芸学会"}]},"item_5_select_19":{"attribute_name":"著者版フラグ","attribute_value_mlt":[{"subitem_select_item":"publisher"}]},"item_5_source_id_11":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AN00025257","subitem_source_identifier_type":"NCID"}]},"item_5_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"00137626","subitem_source_identifier_type":"ISSN"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"李, 同華"}],"nameIdentifiers":[{"nameIdentifier":"39105","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"新美, 芳二"}],"nameIdentifiers":[{"nameIdentifier":"39106","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"中野, 優"}],"nameIdentifiers":[{"nameIdentifier":"39107","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":"2019-07-30"}],"displaytype":"detail","filename":"65(1)_135-144.pdf","filesize":[{"value":"4.1 MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"65(1)_135-144.pdf","url":"https://niigata-u.repo.nii.ac.jp/record/2795/files/65(1)_135-144.pdf"},"version_id":"6339a6f6-c8bf-4af5-a21e-2787707f49bb"}]},"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":"journal article","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"花柱切断受粉法によるテッポウユリ‘ジョージア’の花粉管伸長と種子形成に及ぼす予備受粉の効果","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"花柱切断受粉法によるテッポウユリ‘ジョージア’の花粉管伸長と種子形成に及ぼす予備受粉の効果"},{"subitem_title":"花柱切断受粉法によるテッポウユリ‘ジョージア’の花粉管伸長と種子形成に及ぼす予備受粉の効果","subitem_title_language":"en"}]},"item_type_id":"5","owner":"1","path":["454","487"],"pubdate":{"attribute_name":"公開日","attribute_value":"2008-10-14"},"publish_date":"2008-10-14","publish_status":"0","recid":"2795","relation_version_is_last":true,"title":["花柱切断受粉法によるテッポウユリ‘ジョージア’の花粉管伸長と種子形成に及ぼす予備受粉の効果"],"weko_creator_id":"1","weko_shared_id":null},"updated":"2022-12-15T03:36:00.401392+00:00"}
