However, seedlings with root balls have been reported to show slow post-transplant growth.  In this study, the authors developed a method for processing seeding mixture into blocks before root ball formation with the aim of increasing post-transplant growth.  In the treated group, 6 g of 1 cm-long coconut shell fiber and 10 g of bentonite were added to ordinary seeding mixture, equivalent to 100 g in dry weight.  The modified seeding mixture was used to fill 128 cell-trays.  Under greenhouse conditions, seeds of ‘Kinkei No. 201’ were sown in the trays.  A 0.6% aqueous solution of polyvinyl alcohol was applied to the trays when the cotyledons unfolded.  In the control group, seedlings were grown in ordinary seeding mixture alone.  The treatment did not suppress emergence or subsequent growth of the seedlings.  In the control group, root balls were formed by the 3.0- leaf stage (3 true leaves).  The seeding mixture maintained the shape of the cell, enabling the seedlings to be removed from the cells by a transplanting machine as usual.  Similar shape maintenance of the seeding mixture was also observed in the treatment group, even at the 2.0 and 2.5- leaf stages.  Compared to the 3.0-leaf stage seedlings in the control group, the relative growth rate was higher in the 2.0- and 2.5- leaf stage seedlings of the treated group after transplantation into pots containing growing mixture.  Their relative growth rate was also high during the one-week period after transplanting, when the seedlings were stressed either by withholding water or by waterlogging.  The seeding mixture block processing tested in this experiment enabled younger seedlings to be transplanted compared to conventional methods.  This resulted not only in a reduction in the time taken to raise seedlings but also in the promotion of post-transplant growth under ordinary conditions, as well as under water stress.","subitem_description_type":"Other"}]},"item_1_description_13":{"attribute_name":"レポート・講演番号","attribute_value_mlt":[{"subitem_description":"E","subitem_description_type":"Other"}]},"item_1_description_15":{"attribute_name":"表示順","attribute_value_mlt":[{"subitem_description":"3","subitem_description_type":"Other"}]},"item_1_description_2":{"attribute_name":"ページ属性","attribute_value_mlt":[{"subitem_description":"P","subitem_description_type":"Other"}]},"item_1_description_8":{"attribute_name":"記事種別(日)","attribute_value_mlt":[{"subitem_description":"論文","subitem_description_type":"Other"}]},"item_1_description_9":{"attribute_name":"記事種別(英)","attribute_value_mlt":[{"subitem_description":"Article","subitem_description_type":"Other"}]},"item_1_source_id_1":{"attribute_name":"雑誌書誌ID","attribute_value_mlt":[{"subitem_source_identifier":"AN00164184","subitem_source_identifier_type":"NCID"}]},"item_1_text_6":{"attribute_name":"著者所属(日)","attribute_value_mlt":[{"subitem_text_value":"東京農業大学農学部農学科"},{"subitem_text_value":"福井県立若狭東高等学校"},{"subitem_text_value":"東京農業大学退職"}]},"item_1_text_7":{"attribute_name":"著者所属(英)","attribute_value_mlt":[{"subitem_text_language":"en","subitem_text_value":"Department
