Abstract

This study was initiated to find possibility of substitute of gibberellin acid and to prevent negative girdling effect such as slow growth of 'Niitaka' (Pyrus pyrifolia Nakai) trees, a major pear cultivar, at harvest and at 60-, 90-, and 120-d after storage. Seasonal wiring with 3.0-mm-diameter were applied on the main branch at 70, 80, 90, 110, and 130 days after full bloom (DAF) to compare the fruit quality and storability. Fruit weight and sugar contents were the greatly increased by the wiring treatment at 110 DAF, with the lowest values observed for the wiring at 70 DAF. All the wiring treatments reduced fruit acidity but did not affect fruit firmness. a-value on fruit skin was the highest for wiring at 110 DAF and 130 DAF, advancing fruit ripening. The lowest fruit weight loss was occurred at wiring at 110 DAF. a-value on fruit skin was the highest for wiring at 90 DAF and 110 DAF. Wiring at 80 DAF the most increased floral bud diameter, resulting in the lowest L:D ratio of 1.74 observed. As for the mineral nutrients concentrations of floral buds, the concentration of K (0.63%) and Mg (0.31%) were the highest after 80 DAF wiring treatment, whereas Ca and P concentrations did not differ among treatment plots. The leaf K concentrations was the highest in the 130-day wiring treatment (0.76%) and in the control plot (0.78%), whereas there was no significant difference in the concentrations of either Ca or P among treatment plots. Short periods of wiring increased foliar Mg concentrations. In floral buds, carbohydrates showed a tendency for accumulating at a lower concentrations (7.75%) after 70 DAF wiring treatment, which was a relatively short treatment period. On the other hand, the carbohydrate concentrations in leaves showed a tendency for accumulating at lower concentrations after 130 DAF wiring treatment (2.51%), which is a long treatment period, and in the control plot (2.43%). Wiring increased the size and sugar content of fruits, and influenced fruit storability. For the wiring treatment period was delayed, the carbohydrate concentration in flower buds showed curvilinear correlation and the negative correlation with the carbohydrate in leaf tissue.

본 연구는 배 주요재배 품종인 신고를 이용하여 생장조절제인 지베렐린과 환상박피 효과를 대체 할 수 있는 재배기술을 개발하고자 수행하였다. ${\Phi}3.0mm$인 철사를 사용하여 시기별로 만개 후 70, 80, 90, 110, 130일에 주간에 wiring 처리 후 과실품질 및 수확 후 저장성에 미치는 영향에 대하여 조사하였다. 과실의 과중과 당함량을 조사한 결과 처리시기가 늦은 만개 후 110일 처리구가 다른 처리구와 비교해서 높은 증진 효과를 나타냈으며 처리시기가 빠를수록 낮은 결과를 나타냈다. 산함량은 wiring 처리구가 무처리구보다 낮은 함량을 보였고, 경도는 처리구간 유의적인 차이는 나타나지 않았다. 과피 착색은 무처리구에서 가장 낮은 L값을 보였으나 처리 간 유의적인 차이는 보이지 않았다. 만개 후 110일과 130일 처리구에서 a값이 가장 높게 나타났는데 이는 wiring 처리가 과실의 숙기에 영향을 미치는 것으로 판단된다. 수확 후 저장 60일, 90일 후 과중 변화는 만개 후 110일 처리구에서 가장 낮은 감모율을 보였으며, 당함량과 산함량, 경도는 처리구간 유의적인 차이가 없었다. 저장 기간 중 과실의 밝기를 나타내는 L값은 모든 처리구에서 유의적인 차이가 나타나지 않았으나 a값을 조사한 결과 90, 110일 처리구가 다른 처리구보다 높게 조사되어 처리시기에 따라 a값이 다르게 나타났다. 꽃눈의 생체중과 크기는 처리구간 유의적인 차이는 나타나지 않았다. 꽃눈의 무기성분 함량은 만개 후 80일 처리구에서 K (0.63%)과 Mg (0.31%) 함량이 가장 높았고, Ca과 P의 함량은 처리간 유의적인 차이는 없었다. 잎 내 K 함량은 만개 130일 처리구(0.76%)와 무처리구에서 (0.78%) 함량이 낮았고, Ca과 P의 함량은 처리간 유의적인 차이는 없었다. wiring 처리시기가 늦어짐에 따라 꽃눈의 탄수화물 함량은 곡선형의 상관관계를 보였고 잎의 탄수화물과는 부의 상관관계가 관찰되었다.
