Description

Effects of shading and chemical thinning on the physiological fruit drops were investigated for Satsuma Mandarin in 1975 and 1976. Trees were shaded with black cheese cloth for 5 or 10 days during the months June to July. In case of chemical application, individual blanches were treated with either NAA or BIHN at about 30 days after full bloom and thereafter the trees were shaded for 10 days. Shading of the 5-days period at the stage of physiological fruit drop affected setting considerably, notably the shading at the first and middle of July resulted in the drop of most fruits. Application of NAA or BIHN and following shading remarkably increased the fruit dropping, compared with non-shading controls. It was suggested from these results that during June drop period bad weather, even if it is very short, severely affects fruit setting of Satsuma Mandarin.

温州ミカンの8?9年生樹へ生理的落果期に, 黒色カンレイシャでしゃ光および摘果剤の散布をおこない, その落果におよぼす影響を観察した. 生理的落果期には5日間のしゃ光でも落果が増加し, とくに第2次落果期の7月上旬ないし中旬のしゃ光樹ではいちぢるしかった. 摘果剤(NAA, BIHN)の散布後にしゃ光した場合には, 落果が一層増加した. つまり, 6?7月の生理的落果期には, 日照と落果との間に密接な関係があり, 短期間の天候不良でも落果に大きく影響することが認められた.
