Abstract

The objectives of this research were to determine growth characteristics of commercial cultivars of strawberry grown in Korea, then to differentiate each cuitivar into cropping system based on degree and duration of domancy and to determine starting date of greenhouse heating as forced culture. The date of floral differentiation on cuitivars such as 'Chodong' 'Shuko' 'Nyoho' was from Sep. 20 to 22. However those of 'Toyonoka', 'Reiko', 'Hokowase' etc. were Sep. 26 to 30 and that of 'Morioka(No. 16)' was Oct. 19. It indicated that the cultivars with short dormancy period 'Nyoho', 'Reiko', 'Toyonoka' etc. were suitable for forcing culture, cultivar with ordinary dormancy period such as 'Suhong' was for nearly forcing culture, cultivar with long dormancy period such as 'Hokowase' was for semi-forcing culture, and cultivar with extreamly long dormancy period such as 'Morioka (No. 16)' was for retarding culture.

본 연구는 현재 재배되고 있는 주요 품종들에 대한 생육특성을 조사하고 휴면정도에 따른 보온개화기를 파악함으로써 딸기의 작형분화 양상과 이에 알맞은 품종을 제시하고자 실시하였다. 품종별 화아분화기는 "초동" "슈꼬" "여봉"이 9월 20일 ~ 9월 22일, "풍향" "여홍" "보교조생"등이 9월 26일 ~ 9월 30일, "모리오까"는 10월 19일이었고 휴면정도가 짧은 "여봉" "여홍" "풍향"등은 촉성작형, 휴면정도가 보통인 "수홍"은 준촉성, 휴면정도가 긴 "보교조생"은 반촉성 및 조숙작형, 그리고 아주 긴 "모리오까"는 노지 또는 억제작물에 적합한 것으로 사료되었다 .
