초록

초가을 태풍에 의해 잎 손실이 심해지면 감나무의 과실 품질이 나빠지고 이듬해 생장에 필요한 저장양분이 감소한다. 본 연구에서는 비가림하우스 내 50 L 용기에서 재배한 2년생 '부유' 감나무를 대상으로 9월 상순에 인위적으로 적엽한 후 엽면시비 효과를 검토하였다. 9월 9일에 나무 전체 잎 수의 75%를 고루 적엽한 후 9월 중순과 10월 중순에 요소 0.5%액을 8회 엽면시비하거나 요소와 제일인산칼륨을 교호로 4회씩 엽비시비 (요소+KP 시비구)하는 처리를 하였다. 적엽한 나무 일부는 시비를 하지 않고 대조구로 두었다. 요소 엽면시비로 11월 6일 잎의 N과 P 농도가 대조구에 비해 약간 증가한 반면, 요소+PK 시비에 의해 P와 K농도는 유의적으로 증가하였다. 엽면시비는 과실 비대에 영향을 끼치지 않았으나 과피의 착색을 감소시키는 경향이었다. 과실 당도는 요소 또는 요소+NK 시비로 대조구보다 각각 1.5, $1.0^{\circ}Brix$가 높아졌다. 엽면시비로 세근의 건물중이 증가한 것을 제외하면 영구기관인 지상부 목질과 뿌리의 건물중은 유의적인 변화가 없었다. 영구기관의 N 농도는 엽면시비구에서 높은 경향인 반면 P와 K의 변화는 뚜렷하지 않았다. 가용성당 또는 전분 농도는 엽면시비 방법에 관계없이 신초, 주간 또는 세근에서 증가하였다. 본 연구의 결과는 엽면시비가 잎 손실 감나무의 과실품질과 저장양분 회복에 부분적으로 유용할 수 있음을 나타내었다.

A severe defoliation by typhoon in early autumn reduces fruit quality for the current season and reserve accumulations for the next season. This study was conducted to determine the effects of foliar applications during the autumn on alleviating the damages after defoliation. Leaves of 2-year-old 'Fuyu' trees, grown in 50-L pots under a rain-shelter, were 75%-defoliated on September 9. In mid-September and early October, trees were treated either with eight foliar applications of urea or with four alternating applications of urea and $KH_2PO_4$ (urea + KP application), all at 0.5% (w/v). Trees untreated after the defoliation served as the control. The urea applications slightly increased N and P concentrations of the leaves collected on November 6, while urea + KP applications significantly increased P and K concentrations. Foliar applications did not affect fruit growth, but tended to decrease skin coloration. Fruit soluble solids increased by 1.5 and $1.0^{\circ}Brix$ for urea and urea + KP applications, respectively. There was a significant increase in dry weight of fine root for the foliar application treatments but not in those of aerial woods and larger roots. With the foliar applications, N concentration tended to increase in the permanent organs but not P and K, whereas soluble sugars and starch notably increased in shoot, trunk, or fine root regardless of the different applications. Results indicated that the foliar applications could partially help to restore fruit quality and carbohydrate accumulations in the defoliated trees.
