본 실험은 ABA유도체와 GA₃의 혼합처리가 프리뮬러 ‘Scarlet’과 시네라리아 ‘Early Perfection Red’의 생장 및 개화에 미치는 효과에 대해서 조사하였다. 프리뮬러‘Scarlet’의 화아출현일과 개화일은 대조구에 비해 ABA유도체 0.5㎎ㆍℓ⁻¹+GA3 10.0㎎ㆍℓ⁻¹ 2회 처리에 의해서 각각 9일, 11.3일 촉진되었다. 화수는 모든 처리구가 대조구에 비해서 3배정도 증가하였다. 시네라리아 ‘Early Perfection Red’의 경우 화아출현일과 개화일은 ABA유도체 0.5㎎ㆍℓ⁻¹+GA₃ 10.0㎎ㆍℓ⁻¹ 1회 처리에 의해서 대조구에 비해 각각 4.9일, 8.3일 촉진되었다. 화서수는 동일 처리에 의해서 12개 증가하였다. 이상의 결과로부터 ABA유도체와 GA₃ 혼합 처리는 본 실험에서 공시한 추파일년초의 개화를 촉진하는 효과가 있는 것으로 나타났다.

This study was conducted to determine the effect of ABA derivative and GA₃ mixing treatment on growth and flowering of Primula polyantha ‘Scarlet’and Senecio cruentus ‘Early Perfection Red’. The number of days to flower bud emergence and flowering of P. polyantha ‘Scarlet’ were accelerated 9 and 11.3 days, respectively, by two times application of 0.5 ㎎ㆍℓ⁻¹ ABA derivative + 10.0 ㎎ㆍℓ⁻¹ GA₃ compared to control. Application of chemicals in all treatment increased number of flowers per plant about three times. The number of days to flower bud emergence and flowering of S. cruentus ‘Early Perfection Red’ were accelerated 4.9 and 8.3 days, respectively, by one time application of 0.5 ㎎ㆍℓ⁻¹ ABA derivative + 10.0 ㎎ㆍℓ⁻¹ GA₃. This treatment also increased inflorescences about 12. As the result, ABA derivative and GA₃ mixing treatment was demonstrated to accelerate the flowering and increase flower number of winter annuals in this experiment.
