内容 1.J-455処理によるウンシュウミカン幼果に対する摘果効果の発現ならびに幼果の日齢が効果発現におよぽす影響について検討した.2.間引摘果剤としての利用は満開40〜50日後, 100〜200ppm処理が適当で薬害も認められない.3.効果の発現は, 幼果の日齢の違いによって影響を受け, 日齢の若いもの, 直花果および果径の小さいものに高く現われ, 残果に有葉果率が高まる傾向を示した.4.処理によって果実中の糖含量の増加と, 酸含量の減少の時期的促進が認められた.
The effect of 5-Chloro-1H-3-indazolacetic acid (J-455) on fruit thinning were investigated in field trials with SATSUMA mandarin (Citrus unshiu MARCOVITCH) during 1976 to 1978. The results are summarized as follows: The concentrations of 100 to 200ppm of J-455 was applied 50 days after full bloom (at the end of june drop period) and showed excellent thinning performance (Tables 1, 2 and 7). J-455 was more effective in dropping the smoller and younger fruits than larger and older ones (Tables 3, 4, 8 and 9). It was confirmed that J-455 was very effective in the fruit thinning of SATSUMA mandarin, and did not cause injury on the fruits and leaves. Fruits from treated trees were normal in size (Table 2). An increase of sugar content in juice of treated fruits was much hastened, accompanying with a rapid decrease of citric acid content as compared with those from untreated trees (Fig. 1).
