초록

본 연구는 fatty alcohol(FA)과 6-benzyladenine(6-BA) 처리가 ‘후지/M.9’ 사과의 착과와 과실품질에 미치는 영향을 조사하였다. FA 처리 농도는 500배로 정화 중심화 80% 개화시 1회와 정화 중심화 80% 개화 + 액화 60–80% 개화 시 2회를 각각처리하였고, 6-BA는 처리 농도 1,000배와 500배를 중심과 8mm 일 때 각각 처리하였다. 그리고 FA + 6-BA 혼용처리는 FA 1회 + 6-BA 1,000배와 FA 2회 + 6-BA 500배를 각각 처리하였고, carbaryl은 800배를 중심과 8mm 일 때 처리하였다. 과총당총 착과율을 보면, 무처리구는 정화아는 61.0%였고, 액화아는 37.3%였지만 약제처리구들은 정화아는 35.2–50.6%, 액화아는 9.7–23.8%로 감소하였다. 그리고 정화아 중심과 착과율은 무처리구는 92.6%였고, 약제처리구들은 65.2–94.4%였으나, 액화아의 무처리구는 78.9%였으나 약제처리구들은 17.6–48.7%로 현저히 감소하였다. 정화아의 과총당 무착과율은 무처리구는 2.9%였지만, 약제처리구는 7.5–14.2%로 높았고, 1과 착과율의 경우도 무처리구는 14.1%였으나 약제처리구들은 20.6 –33.9%로 높았다. 그리고 액화아는 무착과율이 무처리구는 19.6%였으나, 약제처리구들은 32.2–69.0%로 현저히 높았다.
그리고 수확시 과실품질은 과중을 제외하고는 모든 처리구들에서 차이를 보이지 않았다. 따라서 FA와 6-BA 처리에 따른 ‘후지’ 사과의 착과율을 현저히 감소시키는 효과를 보였다.

This study was investigated the effect of fatty alcohol (FA) and 6-benzyladenine (6-BA) thinning treatments on the fruit set and fruit quality attributes of ‘Fuji/M.9’ apples. Trees were treated with FA (single, ×500 dilution), FA (double), 6-BA (×1,000 dilution), 6-BA (×500 dilution), FA (single) + 6-BA (×1,000 dilution), FA (double) + 6-BA (×500 dilution), and carbaryl. FA (80.5% a.i.) treatment was applied at 80% blossom of terminal flowers and 60–80% blossom of lateral flowers, and 6-BA (7.4% a.i.) and carbaryl treatments were applied at 8-mm size of central fruit. The total fruit set rate per cluster was observed 61.0% for terminal flowers and 37.3% for lateral flowers in the control but it was decreased to 35.2–50.6% for terminal flowers and 9.7–23.8% for lateral flowers in the thinning treatments, respectively. The rate of central fruit per terminal flower cluster was observed 92.6% in the control but it was 65.2–94.4% in FA and 6-BA treatments. However, the rate of non-fruit set per terminal flower cluster was observed 2.9% in the control but it was increased to 7.5–14.2% in the thinning treatments, and the rate of one fruit set per terminal flower cluster was 14.1% in the control but it was increased to 20.6–33.9% in the thinning treatments. In addition, the rate of non-fruit set per lateral flower cluster was observed 19.6% in the control but it was decreased to 32.2–69.0% in the thinning treatments. The fruit quality attributes were not different in all treatment groups at harvest, except fruit weight. Therefore, our results reveal that FA and 6-BA treatments have the significant effects in reducing the fruit rate in ‘Fuji’ apple.
