Abstract

The objective of this study was to determine the effect of calcium concentrations in fertilizer solution on growth and cut flower quality of chrysanthemum 'Biarritz' To achieve this, deficiency symptom and growth characteristics as influenced by controlled Ca concentrations in fertilizer solution were investigated. The analysis of plant tissue and soil solution of root media were also conducted to secure optimum concentration for plant growth. Calcium deficiency developed on the very youngest leaves and the young leaves developed 'cupped' shape as they expand. The cut flower length of 0, 3.0 and 6.0 mM treatments were 105.8, 106.5, and 107.3cm, respectively. Elevated Ca concentration within the range from 0 to 6.0mM in fertilizer solution increased cut flower weight. The cut flower weight of control and 6.0mM treatment were 51.6 and 59.4 g, respectively. The tissue Ca content of 6.0mM treatment in which crops showed the highest growth among treatments was $3.09\%$ based on the dry weight of the youngest fully expanded leaves. From the results, it seems necessary to maintaining tissue Ca content higher than $2.8\%$. Soil Ca concentrations increased as K concentrations in fertilizer solution were elevated. Ca concentration in 0.0, 1.5, 3.0, 4.5 and 6.0mM treatments were 5.0, 7.4, 12.1, 16.5 and $28.2mg{\cdot}L^{-1}$, respectively, at harvesting stage. It is suggested that Ca concentration higher than $25.4mg{\cdot}L^{-1}$ in soil solution of root media is required to maintain normal growth.

본 연구는 칼슘의 시비농도를 인위적으로 조절한 후 국화를 재배하면서 각 원소의 시비수준이 생육과 절화 품질에 미치는 영향을 구명하고 생육을 우수하게 유지할 수 있는 식물체 및 토양의 한계농도를 밝히기 위하여 수행하였다. Ca결핍 증상은 신엽에서 발생하였고, 신엽이 cup 형태로 구부러지는 기형증상이 나타났다. 정식 109일 후에 조사한 절화장은 무시비구, 3.0mM 그리고 4.5mM Ca처리에서 각각 105.8cm, 106.5cm, 107.3cm로 조사되었다. Ca시비농도가 증가할수록 절화중이 무거워져 무처리구가 51.6g이었고 6.0mM 시비구에서 59.4g으로 측정되었다. 건물중이 가장 무거웠던 6.0mM Ca시비구에서 $3.09\%$의 식물체내 Ca함량을 갖는 것으로 분석되어 국화 'Biarritz'의 정상 생육을 위해서는 $2.8\%$ 이상의 식물체내 Ca 함량을 갖도록 시비하여야 할 것으로 판단되었다. Ca 시비농도가 증가할수록 토양 농도도 뚜렷하게 높아져 무처리구, 1.5, 3.0, 4.5 및 6.0mM 시비구가 각각 5.0, 7.3, 12.1, 16.5 및 $28.2mg{\cdot}L^{-1}$로 분석되었다. 건물 생산량을 고려하여 정상 생육을 위한 최저한계점은 $25.4mg{\cdot}L^{-1}$이라고 판단되었다.
