본 실험은 고랭지 사계성 딸기의 지상부 생장량을 인위적으로 조절하여 생육 및 수량반응을 비교하고자 실시하였다. 생체중은 크라운수가 많을수록 무거워졌으며, 화방당 착과 수에 따른 차이는 없었다. 수확휴식기간은 크라운수가 많을 수록 화방당 착과수가 적을수록 짧아졌다. 상품과수는 크라운수와 착과수가 많을수록 증가하였으나 상품과율은 화방당 착과수 5개에서 74~80%로 가장 높았다. 상품수량은 크라운수 3개와 착과수 11개 구가 26,490㎏ㆍ㏊⁻¹로 방임된 크라운수와 무적과 구의 21,510㎏ㆍ㏊⁻¹보다 23% 증가되었다. 엽수가 7~9매일 때 첫 착과 시 생육이 가장 좋았고, 수확휴식기간도 짧았다. 상품수량은 엽수 7~9매와 화방수 1개였을 때 20,687㎏ㆍ㏊⁻¹로 엽수 4~6매와 화방수 1개 구의 14,799㎏ㆍ㏊⁻¹보다 40% 많았다. This study was conducted to evaluate the growth and yield reaction of ever-bearing strawberry (Fragaria × ananassa Duch.) taking the thinning of reproductive organs like crown and cluster for summer season production at cool region. The cultivar ‘Pechika’ was planted on 28 May, and the split-plot experimental was designed by putting the crown numbers by 1, 2, 3 and noninterference as the control. To compare the fruit set to non fruit thinning, fruits were removed to remain the number of 5, 8, and 11, respectively. At the same time the number of leaves were adjusted to 4 and 6 as the main plot at the first fruiting period as the sub-plot. There was no significant difference in the number of fruits per flower clusters, but the fresh weight of them increased when the number of crown was increased. Harvest breaking period was short with increasing the crown numbers and decreasing the fruit numbers per flower cluster. Marketable fruits per plant were increased with increasing the crowns and the fruits per flower cluster. The marketable fruit was the highest as 74~80% of total production with the treatment of five fruits per flower cluster. The marketable yield was 26.5 tonㆍ㏊⁻¹ that the strawberry was treated as 3 crowns with 11 fruits per flower cluster and it was 23% higher than that of control plot with non-thinning flower cluster. The strawberry grew with the best condition and was shortened the period of first fruiting when the 7~9 leaves were kept at the first fruiting stage. Marketable yield of the above strawberry was 20.7 tonㆍ㏊⁻¹ and the amount 40% higher than other leaf treatments.

본 실험은 고랭지에서 사계성딸기의 고설벤치식 양액재배시 묘의 생산 및 저장방법에 따른 생육 및 수량을 비교하고자 실시하였다. 처리는 주냉장묘, 노지월동묘, 폿트냉장묘와 1년생묘였다. 정식시 묘의 생육량은 폿트냉장이 가장 많았다. C/N율은 1년생이 19.5로 가장 낮았고, 폿트냉장은 39.2로 가장 높았다. 그러나 첫 수확기의 생육량은 처리 간에 큰 차이를 보이지 않았다. 1년생의 첫 수확시기는 다른 처리에 비해 5~9일 늦었다. 1년생의 평균과중은 12.6g 으로 가장 무거웠다. 상품수량은 폿트냉장이 가장 많았고, 1년생, 주냉장, 노지월동 순으로 많았다. 따라서 고랭지에서 단경기생산을 위한 사계성 딸기의 정식묘는 폿트냉장이 가장 좋았다. The growth and yield of ever-bearing strawberry (Fragaria × ananassa Duch.) 'Pechika' were compared after transplant treatment in the raised hydroponic culture on highlands in summer season. The transplant production methods compared were whole plant refrigerated, outdoor over-wintered, pot-refrigerated, and 1-year-old transplants. Growth increment at planting was the highest in pot-refrigerated transplants. C/N ratio of the pot-refrigerated transplants was 39.2 which was higher than 19.5 of 1-year-old transplants. However, the growth increment up to the first harvest were not different among the treatments. The first harvesting date of 1-year-old transplants was August 14, which was 5-9 days late than in the other treatments. The average fruit weight was highest in the 1-year-old transplants with 12.6 g. Marketable yield was the highest in the pot-refrigerated transplants, followed 1-year-old, plant refrigerated, and outdoor over-wintered transplants. Therefore, the pot-refrigerated transplants are recommended for marketable yield increase in ever-bearing strawberry cultured on highlands.

본 실험은 여름작형 착색단고추의 낮은 플라스틱연동하우스 재배시 유인방법 에 따른 수량 및 품질을 비교하고자 실시하였다. 유인방법은 직립과 경사유인이었고, 과실은 6월부터 11월까지 한달 간격으로 수량, 평균과중, 과육두께, 당도, 경도, 과형, 심실수 등을 조사하였다. 상품수량은 6월에 가장 많았으며, 직립유인이 경사유인보다 더 많았다. 6월의 평균과중은 경사유인이 232g으로 직립유인보다 26g 더 무거웠으나, 7월 이후 직립유인이 경사유인보다 더 무거웠다. 과육두께는 직립유인이 경사유인보다 두꺼웠다. 당도는 온도가 낮아질수록 높아졌으며, 직립유인이 경사유인보다 더 높았다. 직립유인의 과형은 수확시기에 따른 차이를 보이지 않았다. 직립유인의 심실수는 3.27~3.34개로 수확기에 따른 차이를 보이지 않았다. This experiment was conducted to analysis the fruit quality according to training method under low plastic film greenhouse cultivation on sweet pepper (Capsicum annuum cv Special) during summer culture. Training treatments were upright training and inclination training, the fruits were examined and analysed with a month interval from June to November on productivity, fruit weight, flesh thickness, contents of soluble solids, hardness, shape, and locules. Productivity per month was the highest on June, upright training harvested more than inclination training. Fruit weight of inclination training on June was 232 g which was higher than 26 g of upright training, but upright training was heavier than inclination training after July. Flesh thickness of upright training was thicker than inclination training. Soluble solids content increased with the decrease of temperature, upright training was higher than inclination training. The fruit shape of upright training was not significant according to harvesting date. The number of locules of upright training was 3.27~3.34, and it was not significant according to harvesting date.
