Abstract
In order to provide cool night to strawberry plant with cool air and water, an abandoned cool mine was utilized. It's effects on flower induction and fruit yield in 4 different cultivars were examined. After 70 days of transplanting, flowering frequency was below 65% and 100% in control and treatment of night cooling, respectively and regardless of cultivars. Number of flower buds and flower clusters were higher in treated plants compared with the control. Average time until flowering was much less in treated plants. In terms of yield weight and total yield, 'Suhong' was found to be the best cultivar, averaging 24.2g fruit. Cooling contributed to the 6-7 times of increase in total yield within the frame of harvesting times. The fruit were harvested at 80-97 days after transplanting.
폐광에서 유출되는 냉기 및 냉수를 활용하여 시설내에서 딸기를 야냉단일처리하여 개화, 화방 및 수량에 미치는 영향에 대하여 조사하였다. 개화율은 정식 70일후 대조구에서 65% 이하로 나타났지만, 야냉단일 처리구에서는 품종과 처리에 관계없이 100% 이었다. 화방 및 화뢰수는 전 품종에서 대조구에 비해 야냉단일처리구에서 현저히 증가하였고, 평균 개화일수도 야냉처리에서 7-15일 정도 단축되었다. 과실 및 총수량은 '수홍'이 5주 처리에서 개당 24.2g으로 가장 많았고, 대조구에 비해 야냉단일 처리구에서 수확기간내의 총수량이 6-7배 증가하였으며, 평균 수확일은 정식 후 80-97일로 나타났다.
