Description
夏季高温期におけるブドウ'BK シードレス'の果皮着色促進を目的として, 環状剥皮処理および主枝の局部冷却処理が果実の着色および品質に及ぼす影響を調査した. 環状剥皮処理では, 果皮着色開始前に幅2 cmの環状剥皮処理を行うことにより, 1か月早く収穫できる程度に果皮着色および糖度上昇が促進された. 主枝の局部冷却処理は主枝内部温度を部分的に低下させたが, その効果が及ぶ範囲は狭く, 着色促進効果も限定的であった.
The effects of girdling or partial cooling of scaffold branches were investigated for the improvement of berry coloration in 'BK Seedless' grape (Muscat Bailey A × Kyoho) under the high temperature condition in summer. Girdling of 2cm width carried out around veraison promoted berry coloring and increased sugar content of the berries. Partial cooling of scaffold branches with running cool water (15℃) made the temperature in the inner part fall to some extent; however, the coloring treatment did not show the significant effect on berry coloration and quality.
