본 연구는 저온처리 및 생장조절제가 무스카리 "Early Giant"의 생장과 개화에 미치는 영향에 대해서 조사하였다. 8주간 저온처리에 의해서 맹아까지의 소요 일수는 9.9일로 무처리 15.8일에 비해 4.9일 단축되었다. GA₃ 100mg·L^-1와 3주간 저온처리에 의해서 8.8일로 가장 빠른 맹아를 나타내었다. 개화소요일수는 8주 저온처리의 경우 75일로 무처리의 165.1일에 비해 90.1일이나 단축되었다. 그러나 저온처리기간이 길어질수록 화경수가 감소하였다. 개화소요일수는 GA₃ 100mg·L^-1 처리와 3주와 7주 저온처리에 의해서 대조구에 비해 각각 7.6, 5.8일 단축되었다. 그 외의 생장조절제 처리는 저온처리구와 비슷한 경향을 나타내었다. 이상의 결과로부터 무스카리도 다른 추식구근과 마찬가지로 개화촉진을 위해서는 저온처리와 GA처리가 효과적이라는 것을 알 수가 있었다. 그러나 장기저온처리는 화경수를 감소시켜 품질하락의 원인이 되기 때문에 적절한 저온처리는 45일 이내로 판단되었다.

This experiment was conducted to clarify the effect of chilling treatment and growth regulators on the growth and flowering of Muscari armeniacum "Early Giant". The days to sprouting under the 8-week chilling treatment was 9.9 days, which was shortened by 4.9 days compared to 15.8 days of control. The earliest sprouting appeared on 8.8 days by GA₃ 100㎎mg·L-1 with 3-week chilling treatment. The days to flowering was 75days under 8week chilling treatment, shortening 90.1 days compared to 165.1 days of control. But the number of stalks was decreased with the long period of chilling treatment. The days to flowering were shortened by 7.6days, 5.8days under GA₃ 100㎎·L-1 with 3-week, 7-week chilling treatments respectively compared to the control. Other growth regulators showed similar results of chilling treatment. From the above results, GA with chilling treatment was effective for the forcing of flowering of M. armeniacum "Early Giant" like other fall planting bulbs. But because the long chilling treatment decreased the number of flower stalks causing the quality decrease, the most appropriate days of chilling treatment was considered 45 days.
