Abstract

This study was conducted to evaluate the influence of fruit setting order by flower cluster on the fruit weight and the soluble solids content for the strawberry of 'Seolhyang' cultivar. The first flower cluster had higher fruit number, fruit weight, soluble solids content and ratio of large fruit compared to the second and third flower cluster. The fruit set on the upper position fruit in the same flower cluster had higher fruit weight and the soluble solids compared to the fruit set on the lower position fruit in the flower cluster. The fruit weight was highly positive correlated with the soluble solids content. The result indicated that the number of fruit set for marketable yield seemed to be 9-10 per the first flower cluster, 6 per the second flower cluster, 4 per the third flower cluster and 3 per the fourth flower cluster in 'Seolhyang' cultivar.

본 연구는 딸기 '설향' 품종의 화방별 착과순서에 따른 과중 및 당도의 변화를 조사하여 각 화방별로 착과량 조절 기준의 타당성을 검정하고자 하였다. 1화방은 2, 3화방에 비하여 착과수, 과중, 당도, 대과성 과실의 비율이 높았다. 동일 화방 내에서도 상위 과실은 하위에 착과된 과실보다 과중이 증가하였고, 당도도 높았다. 과실의 과중이 증가할수록 당도가 증가하여 과중과 당도는 높은 정의 상관관계를 보였다. 설향 품종의 각 화방별 적정 착과수는 1화방 9~10개, 2화방 6개, 3화방 4개, 4화방 3개 정도 착과시키는 것이 상품수량을 증가시킬 수 있을 것으로 생각된다.
