Description
早期加温栽培‘デラウェア’(1月加温開始)の燃油消費量を削減するため,隔日で加温機の設定温度を慣行温度基準(慣行区)より5°C低くする隔日変温管理が生育と果実品質に及ぼす影響について調査した.

夜間のみを5°C低下させる夜間隔日処理は,慣行区と比較して生育期(果粒軟化開始期,成熟期),葉色,果粒肥大および果実品質にほとんど影響を及ぼさなかった.また,その時の加温期間中のA重油削減率は8%程度であった.一方,昼間と夜間を5°C低くする昼夜隔日処理では,生育期と葉色に慣行区と有意な差はなかったが,果径が処理14日後から成熟期まで慣行区より小さく推移した.また,昼夜隔日区の果房重と果粒重は,慣行区より劣った.

以上のことより,現地へ隔日変温管理を導入する場合,結実判明期から加温終了時までの期間,夜間の設定温度を5°C低くする方式がよいと考えられた.
Description Alternative
We investigated the effect of time-dependent temperature management conducted every other day (TTMD) on the growth and berry quality of ‘Delaware’ grapes under forcing culture from January to May in order to reduce fuel consumption. This method involved lowering the standard temperature setting for forcing (control) by 5°C on alternate days. Grapevines that were grown under TTMD at night exhibited no significant differences in development (veraison, maturity), leaf color, berry growth, or berry quality compared with the control. However, fuel oil consumption was reduced by 8%. Grapevines that were grown under TTMD during the day showed no difference in the developmental period of berries or leaf color compared with the control. However, they showed lower levels of berry growth than the control from 14 days after the TTMD treatment to maturity; furthermore, they showed lower cluster and berry weights than the control. Therefore, it was concluded that TTMD is a suitable option for viticulturists if used at night from the time of berry set until the end of forcing.
