The endogenous levels of abscisic acid (ABA) and indole-3-acetic acid (IAA) were analyzed by gas chromatograph-mass spectrometry(GC-MS), and those of gibberellins (GA)-like substances were determined by the dwarf rice bioassay. Fruitlet abscission occurred mainly from 13 to 62 DAF and peaked at 41 DAF. A relatively rapid increase of fresh weight of fruitlets occurred until 41 DAF; thereafter, the growth rate was moderate. The weight of the calyx increased until 13 DAF. The ABA concentrations in fruitlets was higher from flowering to 28 DAF than the remainder period. The calyx at 13 DAF had the maximum ABA concentration of all parts analyzed. IAA in the ovary / fruitlet increased about 18 times in content and 5 times in concentration from -5 to 0 DAF, and decreased to less than half in content by 13 DAF. The concentration of GA-like substances in fruitlets at flowering was also high, and increased at 41 and 122 DAF. At 5 days before flowering, the calyx had a higher concentration and content of three phytohormones than the ovary. These results suggest that the genetical increases of IAA and GA-like substances in the fruitlet of the parthenocarpic persimmon during flowering may result in continued growth, but the interaction between increased ABA and decreased IAA and GA-like substances in the fruitlet before fruitlet-drop may induce its abscission.","subitem_description_language":"en","subitem_description_type":"Abstract"},{"subitem_description":"単為結実のカキ‘平核無’の子房／幼果を開花前5日から開花後122日まで採取し，アブシジン酸（ABA）とインドール酢酸（IAA）はガスクロマトグラフィー質量分析計で，ジベレリン（GA）様物質はわい性イネの生物検定で各内生量を測定した．幼果は開花後41日をピークとして13～62日に集中的に落果した．幼果の相対的な生重量の増加は，開花後41日までは急激で，以後はゆるやかであった．がくの生重量の増加は開花後13日までにほぼ終わった．幼果のABA濃度は開花日から28日後まで高く，その後低下した．がくのABA濃度は開花後13日にすべての分析値中の最高値であった．子房中のIAAは，開花前5日と比べて開花日に含量が約18倍に増加して高濃度を示し，開花後13日には含量が半分以下に減少して濃度も急低下した．幼果のGA様物質の濃度も，開花日に高い値を示し，その後41および122日に上昇した．開花前5日のつぼみではがくの3種類の植物ホルモンは濃度および含量とも，子房よりも高い値であった．以上の結果から，カキの単為結実の幼果では開花時のIAAおよびGA様物質の遺伝的な増加が幼果の生長を継続させること，ならびにその後の幼果中のABA濃度の上昇およびIAAとGA様物質の濃度の低下が共同的に落果を促進することが示唆された．","subitem_description_language":"ja","subitem_description_type":"Abstract"}]},"item_5_full_name_3":{"attribute_name":"著者別名","attribute_value_mlt":[{"nameIdentifiers":[{"nameIdentifier":"68","nameIdentifierScheme":"WEKO"}],"names":[{"name":"児島,
