과다결실이 예상되는 20년생 ‘흥진조생’ 온주밀감나무를 선정하여 1)가을전정, 2)가을 전정＋아주지 부분 전적과, 3)이듬해 봄 관행 전정, 4)봄 관행 전정＋아주지 부분 전적과 처리를 하고, 5)무처리로 대조구를 두었다. 1차년도 시험에서는 모든 처리에서 화엽비가 높아 예상대로 많았으나 처리 간에는 차이가 없었다, 이듬 해 2차년도 시험에서는 모든 처리에서 착화량이 낮은 경향이었으나 처리 간에는 차이가 없었다. 수량변동률을 보면 가을 전정＋아주지 부분 전적과 3.1％, 봄관행 전정＋아주지 부분 전 적과 9.3％, 가을 전정구 12.9％, 무처리 21.0％, 봄 관행 전정 25.2％ 순으로 전정 및 부분 전적과 방법에 의해 해거리를 경감시킬 수 있는 것으로 나타났다. 당도는 2000년도에는 봄 관행 전정 또는 봄 관행 전정＋아주지 부분 전적과에서 높은 경향을 나타내었고 2001년도에는 2000년도에 비해 높았는데 처리 간에 차이는 없었다. 산도는 가을 전정＋부분 전적과와 봄 전정＋아주지 부분 전적과에서 낮은 결과를 나타내었으나. 이듬해에는 처리 간에 차이는 없었다.

20 years old ‘Okitsu wase’ (Citrus unshiu Marc.) were treated of 1)pruning in autumn, 2)pruning in autumn ＋ partial and all defruiting of secondary scaffold branches on June, 3)pruning in spring, 4)pruning in spring ＋ partial and all defruiting of secondary scaffold branches on June and 5)control. Floral leaf ratio was very high in all treatments in 2000 as expected, but there were no significant difference among the treatments. In 2001, floral leaf ratio was very low in all treatments as expected off year, and there were no significant difference among the treatments. Yield changes rate for the year were 3.1, 9.3, 12.9, 21.0, and 25.2％ in pruning in autumn ＋ partial and all defruiting of secondary scaffold branches on June, pruning in spring ＋ partial and all defruiting of secondary scaffold branches on June, pruning in autumn ＋ no defruiting, control and pruning in spring ＋ no defruiting, respectively, resulted very low tendency in order of this treatments. The results indicated that alternate bearing phenomenon could be reduced by pruning and defruiting method. There was a little higher tendency of soluble solid content in spring pruning or defruiting plot of secondary scaffold branches on June compared to other treatments and significant difference among treatments in 2000, but no significant difference among treatments in 2001. Acidity was a little lower in spring pruning＋partial and all defruiting on June compared to other treatments in 2000, but there were no significant difference among treatments in 2001.
