우수한 자생식물자원인 산국의 수량과 유효성분을 높이기 위해 식물생장조절제 ABA와 SA를 처리한 결과를 요약하면 다음과 같다. 1. 꽃의 건물수량은 ABA, SA과 ABA+SA 처리구에서 무처리구보다 증가되었으며, ABA 처리구보다는 SA 처리구가 증수되었다. 2. 무기성분의 함량변화는 SA 처리구가 다른 처리구들에 비하여 질소, 인산, 마그네슘의 함량이 증가하였으나 칼륨의 흡수는 오히려 감소하였다. 3. 아미노산함량은 SA 처리구와 ABA+SA 처리구는 ABA 처리구보다 높았다. 4. 생장조절제처리는 정유함량을 증가시켰으며, 그 반응은 monoterpenoid계 화합물보다는 sesquiterpennoid계 화합물에서 더 민감하였다. 5. Cumambrin A의 함량은 ABA 처리구에서 증가하였고, SA 처리구에서는 차이가 없었다.

Chrysanthemum boreale M. is an important medicinal plant that has been historically used in herbal medicine and in the health food throughout East Asia. This study was conducted to investigate the influence of abscisic acid (ABA) and salicylic acid (SA) on plant growth, mineral content and effective components, such as essential oil, amino acid and cumambrin A, by means in order to increase the productivity and the quality of flowerheads in the plant. Yields of flowerheads were increased by 12.7%, 21.7% and 15.5% by ABA, SA and both treatments, respectively, as compared with the control. Inorganic nutrient content was changed by PGRs; SA treatment was increased by nitrogen, phosphorus and magnesium content but decreased by potassium of C. boreale M. flowerheads. Total content of amino acid was increased by SA but decreased by ABA treatment. Essential oil content and yields were increased to 9.7% and 33.8% by SA treatment. Moreover, the content of terpene, monoterpenoids and sesquiterpenoids, were improved by ABA treatment, especially, germacrene-D content was increased by 39.1%, as compared to control. In addition, yields of cumambrin A, sesquiterpene compound exhibiting blood-pressure activity, increased in all PGRs treatments, but its concentration in the C. boreale M. flowerheads only increased by ABA and both treatment. The experiment suggests that PGRs using ABA and SA could increase the yields and quality of C. boreale M. flowerheads.
