In the present paper, from the comparison between the developmental states of roots and buds in the vertical seedlings and those in the horizontal for sixteen days, the unilateral effects of gravitational stimulus are discussed. And it is briefly referred to whether or not any interrelation exists between such gravitational effect as mentioned above and the root condition of riceseedlings at the start of experiment. 1. From the experiment through water culture on the seedligs with roots excised and without any tiller, the followings were obtained. a) Seedlings in the horizontal plot produced new roots more numerously than those in the vertical plot throughout the experimental period, and the difference inthe number of new roots reached the maxium (18 per cent more in the horizontal than in the vertical) on the eighth day, then gradually decreased. This fact was mainly attributable to the difference in the number of roots derived from the uppermost or the adjacent rooting nodes. b) In the horizontal plot, the growth of tiller buds located on the nodes lower than those with the most active leaves at the biginning of the experiment was more accelerated from the fourth' day than in the vertical plot. But it was not until the eighth day that the elongation of tiller buds on the nodes upper than those mentioned above in the horizontal plot exceeded that in the vertical. 2. In another experiment, the seedlings with roots entirely excised, partially excised, and with intact roots were set vertically and horizontally, respectively. From the result it was found that just in the seedlings with roots excised, the roots newly emerged in the horizontal plot were abundant in contrast to the vertical plot. It was, furthermore, shown that the more roots were cut off before the treatment, the larger became the difference in the number of new roots between both plots. 3. An experiment through soil culture showed that the horizontal fixation of the main axes had an effect on the increase in the numもer oJ roots and tillers just in the case where the rice seedlings were transplanted, but not in the case where those were not.","subitem_description_type":"Abstract"}]},"item_3_full_name_2":{"attribute_name":"著者(ヨミ)","attribute_value_mlt":[{"nameIdentifiers":[{}],"names":[{"name":"イシイ, シゲキ"}]}]},"item_3_full_name_3":{"attribute_name":"著者別名","attribute_value_mlt":[{"nameIdentifiers":[{}],"names":[{"name":"ISHII, Shigeki"}]}]},"item_3_publisher_32":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"奈良学芸大学"}]},"item_3_source_id_7":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"03693937","subitem_source_identifier_type":"ISSN"}]},"item_3_source_id_9":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AN00181015","subitem_source_identifier_type":"NCID"}]},"item_3_version_type_15":{"attribute_name":"著者版フラグ","attribute_value_mlt":[{"subitem_version_type":"VoR"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"石井, 滋規"}],"nameIdentifiers":[{}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2017-02-24"}],"displaytype":"detail","filename":"NUE14_2_71-81.pdf","filesize":[{"value":"699.3 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"NUE14_2_71-81.pdf","url":"https://nara-edu.repo.nii.ac.jp/record/8625/files/NUE14_2_71-81.pdf"},"version_id":"8abe3bec-4afc-4327-a350-356301cc6885"}]},"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":"水稲苗の発根と分げつ芽の発育に及ぼす重力の影響Ⅱ","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"水稲苗の発根と分げつ芽の発育に及ぼす重力の影響Ⅱ"}]},"item_type_id":"3","owner":"4","path":["1488"],"pubdate":{"attribute_name":"公開日","attribute_value":"2010-05-24"},"publish_date":"2010-05-24","publish_status":"0","recid":"8625","relation_version_is_last":true,"title":["水稲苗の発根と分げつ芽の発育に及ぼす重力の影響Ⅱ"],"weko_creator_id":"4","weko_shared_id":-1},"updated":"2023-05-16T08:21:34.646962+00:00"}
