Abstract

This study was conducted to investigate the effects of crown numbers on growth and yield of ever-bearing strawberry (Fragaria × ananassa Duch.) 'Goha' cultivar. Strawberry seedlings were planted with 55 × 30 cm distance on April 29, and the randomized block experimental was designed by putting the crown numbers by 1, 3, 5 and crown-unremoved as the control. At the early growth stage, as the numbers of crown decreased, the size of leaf became larger and inflorescence diameter became thicker. Plant height became higher as the number of crown increased at the final harvesting time. Fresh weight of crown-unremoved plants was 118 g, showing 77.2 g higher than that of plants with one crown. Numbers of the developed inflorescence of plants with five crowns and crown-unremoved was 20.1, whereas 6.8 of plants with one crown, resulted in 13.3 more crowns. However, crown number did not significantly affect the fruit quality. As the crown number increased, the average fruit weight was lighter and the marketable fruit rate was shown to decrease significantly. The marketable yield of crown-unremoved plants was 17,372 kg･ha-1, showing 68% higher than plants with one crown. Therefore, crown management without thinning crowns was recommended and inflorescence thickness less than 3 mm should be removed for successful production of ever-bearing strawberry ‘Goha’ cultivar during summer season.

본 실험은 고랭지에서 신품종 사계성 딸기 ‘고하’ 품종의 생육 및 수량에 영향을 미치는 관부수를 구명하고자 실시하였다. 정식은 4월 29일에 재식거리를 55 × 30cm로 실시하였으며, 시험구 처리는 관부수를 1, 3, 5개로 하고 대조구로 방임을 두었다. 생육초기에 관부수가 적을수록 잎은 커졌고, 화방경은 굵어졌다. 최종수확 시 초장은 크라운수가 많을수록 길어졌다. 생체중은 관부수 방임구가 118g으로 관부수 1개구의 40.8g보다 77.2g이 더 무거웠다. 발생된 화방수는 관부수 5개구와 방임구가 20.1개로 관부수 1개구의 6.8개에 비해 13.3개가 더 많았다. 그러나 관부수에 따른 과실품질의 유의적인 차이는 보이지 않았다. 관부수가 많을수록 평균과중은 가벼웠으며, 상품과율은 감소하였다. 상품수량은 관부수 방임구가 17,372kg･ha-1로 가장 많았으며, 관부수 1개구에 비해 68% 증수되었다. 따라서 고랭지 사계성딸기 ‘고하’의 여름재배 시 안정생산을 위해서는 관부는 방임하며, 화방굵기가 3mm 이하인 화방은 제거하는 것이 가장 적당하였다.
