Abstract

This experiment was conducted to compare effects of summer pruning at different times and dormant pruning on shoot growth and yield of northern highbush blueberry. Using 7 (2018) to 9 (2020) years old ‘Duke’ bushes grown in 180 L containers, summer pruning was treated on June 20 (around 30 days after harvest), July 20, and August 20 consecutively in both 2018 and 2019 removing 30% of the total woods, while dormant pruning (conventional) was on January 20 in both 2019 and 2020. Summer pruning reduced shoot growth the following year, especially when treated in late summer. Total shoot length per bush decreased to 47%, 37%, and 33% on October 15, 2020 in June, July, and August pruning, respectively, compared with that of dormant pruning. Summer pruning at different times in 2018 and 2019 did not affect berry characteristic in the following year. Yield per bush was not significantly changed in 2019, but it decreased by 21 to 38% in 2020 in the summer pruning treatments compared with 2.9 kg of the dormant pruning. It was concluded that consecutive summer pruning in ‘Duke’ under unheated plastic house could weaken the shoot growth with reducing yield.

본 시험은 무가온 시설재배 조건에서 북부하이부쉬 블루베리의 전정시기가 영양 생장과 과실 생산에 미치는 영향을 구명하고자 수행되었다. 180L 용기에서 재배한 7－9년생 ‘듀크’ 품종을 대상으로 2018년과 2019년 6월 20일(수확 후 30일경), 7월 20일, 8월 20일에 하계전정을 실시하였고, 2019년과 2020년 1월 20일에 동계전정(관행)을 목질부 생장량의 30%를 제거하는 방법으로 처리하였다. 하계 전정구들은 2년 연속 전정 이듬해인 2020년 10월 15일에 신초 생장이 현저히 감소하였는데, 주당 총 신초장은 6월, 7월, 8월 전정구가 동계 전정구에 비해 각각 47%, 37%, 33%로 작았고 하계전정 시기가 늦을수록 신초 생장이 감소하는 경향이었다. 하계전정 1년차와 2년차 이듬해의 과실 특성은 전정 시기의 영향이 없었고, 주당 수량은 전정 1년차 이듬해인 2019년에는 차이가 없었으나 2년 연속 처리 이듬해 2020년에는 동계 전정구가 2.9kg인데 반해 하계 전정구들은 동계 전정구에 비해 21~38%가 감소하였다. 따라서 무가온 시설재배 조건에서 북부하이부쉬 ‘듀크’의 하계 전정은 동계 전정에 비해 수세가 약화되어 수량이 감소할 수 있는 것으로 나타났다.
