Abstract

This study was carried out to investigate effects of stock plant management and foliar spray of GA on the flower quality in hydroponically grown chrysanthemum 'Shinma'. In the growth and development as affected by stock plant management, cut flower length, petal number and cut flower weight were the best in the plot of long day and chilling treatment showed 114 cm, 298 and 102 g, respectively. Chlorophyll content(SPAD-value) was the highest in the plot of foliar spray of diluted Molbia(1 : 500). Flower quality according to concentration and spray time of gibberellin showed a different pattern. Cut flower length was the longest in the plot of solution diluted to 1 : 1,000 spraying before flowering at 60 days, petal number was the most in 1 : 500 at 60 days, and cut flower weight was the heaviest in 1 : 2,000 at 60 days, respectively. However, peduncle length was tended to be elongated with foliar spray of gibberellin solution diluted to 1 : 500 or 1 : 1,000 before flowering at 45 days.

본 연구는 직삽 양액재배에 의한 '신마'품종의 절화품질 향상시키고자 양액 pH조정 비료종류와 모수포 관리 및 지베렐린처리 효과를 알아보기 위해 실시하였다. 모수포 관리에 따른 절화장은 무처리(관행) 103 cm에 비해 모수포관리(온도,일장) 처리가 114 cm로 가장 컸고, 꽃잎수도 무처리(관행) 259개/송이에 비해 모수포관리(온도, 일장) 처리가 298개로 가장 많았고, 절화중은 모수포관리(온도,일장) 처리가 102g/본 가장 무겁게 나타났다. 엽록소(SPAD-value)는 영양관리(몰비아 500배)처리가 57.2로 가장 높게 나타났다. 지베렐린처리 농도와 살포시기에 따른 절화장은 무처리(관행) 103 cm에 비해 지베렐린 1,000배 개화 60일전 처리가 121 cm로 가장 컸고, 꽃잎수도 무처리(관행) 259개/송이에 비해 지베렐린 500배로 개화60일전 처리가 308개로 가장 많았고, 절화중은 2,000배 개화60일전 처리가 110.7 g/본 가장 무겁게 나타났다. 하지만 꽃목길이는 관행(무처리) 3.5 cm에 비해 500배 개화45일전 처리 10.4 cm와 1,000배 개화45일전 처리가 9.7 cm로 도장하는 경향이었다.
