Abstract
본 연구는 착색단고추 수경재배 시 배양액 내 Ca과 길항하는 세 가지 양이온(K, Mg 및 $NH_4$)의 이온비율에 따른 착색단고추의 생육과 배꼽썩음과 발생에 미치는 영향을 밝히고자 수행하였다. 배양액 내 K, Mg 및 Ca과 같은 세가지 양이온의 종류와 비율은 착색단고추의 생육에 영향을 미치기는 하나 줄기와 잎의 생육보다는 착색단고추 과실의 생육과 품질에 더 큰 영향을 미치는 것으로 나타났다. 특히 배꼽 썩음과 발생과 이로 인한 상품과율은 양이온의 종류와 비율에 따라 큰 영향을 받는 것으로 나타났다. Ca:K = 1:2 처리와 Ca:(K + Mg + $NH_4$) = 1:2 처리에서 각각 70.3%와 86.3%의 가장 높은 배꼽썩음과 발생률이 관찰되었고, 상품과율도 각각 19%와 13.7%로 가장 낮았다. 배꼽썩음과 발생과 배양액 내 K이온의 상관성(r = $0.82^{**}$)이 가장 높았고 그 다음이 $NH_4$-N(r = $0.65^{**}$)이었으며, Mg은 본 실험에서 배꼽썩음과 발생에 영향을 미치지 않는 것으로 나타났다. 두가지 이상의 양이온을 혼합하여 처리한 경우 K + Mg은 r = $0.46^*$이었고 K + Mg + $NH_4$는 r = $0.92^{**}$로 배꼽썩음과 발생에 가장 큰 영향을 미쳤다. This study aimed to investigate the responses of plant growth and blossom-end rot (BER) incidence to calcium (Ca) and its three kinds of antagonistic cations (K, Mg, and $NH_4$-N) with various ratios in nutrient solution for sweet paper (Capsicum annuum L. 'RZ208'). Both Ca to each cation and Ca to a series of cation combinations, such as potassium (K), ammonium nitrate ($NH_4$), or magnesium (Mg) were more influential to the fruit growth and quality than plant growth. Especially, the BER incidence was significantly influenced by the ratio treatments. For examples, when Ca:(K + Mg) or Ca:(K + Mg + $NH_4$) ratio was 1:2 the highest incident rate of BER about 70.3 or 86.3% was observed, lowering the marketable yield to 19 or 13.7% of the total yield, respectively. The correlation coefficiencies (= r) to relationships between the BER and K as well as BER and $NH_4$ were 0.82 (P < 0.05) and 0.65 (P < 0.05), respectively. Combination only with the Mg element was not correlated with the BER incidence. However, when both of the K and Mg concentrations were 0.65 (P < 0.05). The highest correlation coefficiency, 0.92 (P < 0.05), was found to a relationship between the BER and the tree elemental combination.
