Abstract

As an alternative to methyl bromide (MeBr) fumigation for the control of quarantine pests of pears (Pyrus pyrifolia cv. Niitaka), the effect of gamma irradiation (0.5~3 kGy) was comparatively investigated. Insects found in the pears were identified Tetranychus urticae Koch and Panonychus ulmi Koch, which were of quarantine importance. These insects were easily destroyed by MeBr even one day after fumigation. Whereas irradiation at 0.5~2 kGy was not enough to reach the mortality, even if 3 kGy showed the same mortality as MeBr after 17 days of treatment. Respiration of pears was stimulated by both increased doses of irradiation and MeBr fumigation. The rates of surface blackening and core browning were accelerated by MeBr rather than higher doses of irradiation. While the changes in flesh firmness and surface color were more apparent in irradiated samples at above 2 kGy than MeBr. There were negligible differences in the contents of titratable acidity, acetaldehyde and ethanol by the treatment conditions except for 3 kGy-irradiated group. Sensory evaluation showed that mere than 1 kGy was the threshold to induce the significant changes in quality of pears.

배(Pyrus pyrifolia cv. Niitaka) 과실의 검역해충 사멸을 위하여 methyl bromide (MeBr) 훈증의 대체방안을 연구할 목적으로 감마선 조사의 적용가능성을 검토하였다. 배 과실에서 검역대상 해충으로 점박이응애(Tetranychus urticae Koch)와 사과응애(Panonychus ulmi Koch)가 동정되었다. 이들 해충들은 MeBr 훈증에 의해 처리 1일 후 완전 박멸되었으나, 감마선 처리에 의해서는 지효성을 보이면서 조사선량에 비례하여 사충률이 증가되었다. 과실의 호흡량은 조사선량의 증가와 MeBr 훈증에 의해 증가되었다. 과실의 과피 흑변과 과심 장해는 MeBr 처리에 의해 크게 촉진되었으며, 감마선 처리에서도 선량에 비례하여 촉진되었다. 과육경도와 표면색도는 MeBr의 영향 보다는 2 KGy 이상의 감마선 조사에 의해 과육의 연화와 표면색도의 변화가 나타났다. 적정산도는 3 kGy 조사에 의해 다소 낮았으며, 아세트알데히드 함량은 처리조건의 영향을 받지 않았으나, 에탄올 함량은 3 kGy 조사에 의해 증가되었다. 관능적 품질특성은 1 kGy 이상의 감마선 조사에 의해 유의적으로 저하되었다.
