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.
