ハイブッシュブルーベリーの開花日と成熟日の関係 Relationship between Anthesis and Harvest Date in Highbush Blueberry Suzuki, Akira Kawata, Naoko berry growth flowering date harvesting date highbush blueberry The relationship between anthesis, harvest time, and fruit quality using 840 flowers of 'Jersey'highbush blueberry was investigated. The time of flowering and berry harvest was significantly correlated (r=0.485) at the 1% level. Thus, flowers which bloom early produced early maturing berries. The highest coefficient of correlation existed between harvest date and the number of days to maturity (r=0.718), whereas that between harvest date and berry weight was negatively but highly correlated (r=-0.660). Considering this bloom characteristic, the possibility exists that harvest date can be manipulated by controlling flowering time through the application of a plant growth regulator, adjusting the cluster size, and/or the degree of pollination and seed set. ハイブッシュブルーベリーにおける開花時期と成熟時期の関係を検討するため, 成木の'Jersey'を供試して, 約840花の開花日と成熟日および果実品質を調査した.その結果, 開花日と収穫日の関係は1%水準(r=0.485)で有意差が認められ, 開花の早い花ほど収穫日が早いことが明らかとなった.調査項目の中で最も相関の高かった関係は, 収穫日と成熟日数の関係で, 次いでそれらと果粒重の関係であった.この開花特性から, 花房の整形, 植物生長調節剤の利用等により開花時期を制御することで, 収穫時期を制御できる可能性が示唆された. journal article Japanese Society for Horticultural Science 2001-01-01 VoR application/pdf Journal of the Japanese Society for Horticultural Science 1 70 60 62 0013-7626 https://iwate-u.repo.nii.ac.jp/record/9193/files/jjshs-v70n1p60-62.pdf https://iwate-u.repo.nii.ac.jp/records/9193 10.2503/jjshs.70.60 Copyright (c) Japanese Society for Horticultural Science
