表１に示されるように、本発明の肥料成分吸収促進剤を散布することにより植物中のオーキシン含有量が増大することが見出された。したがって、肥料成分吸収促進剤が施用された植物では、オーキシンによる細胞膜プロトンポンプの活性化を介して、カリウム等の肥料成分の吸収が促進され、植物の伸長生長が誘導されると考えられる。一方、水のみが散布された比較例１および直鎖飽和脂肪酸であるステアリン酸を含む比較液が散布された比較例２では、施用された植物におけるオーキシンの含有量の増加は認められなかった。市販の肥料成分と共に本発明の肥料成分吸収促進剤が施用された実施例２では、植物中のオーキシン含有量がさらに増大された。したがって、本発明の肥料成分吸収促進剤を植物の肥料成分と共に用いることで、肥料成分の吸収効率が高められた優れた植物生長促進効果を有する植物用肥料が提供され得る。 As shown in Table 1, it was found that the auxin content in plants increased by spraying the fertilizer component absorption enhancer of the present invention. Therefore, in plants to which the fertilizer component absorption enhancer is applied, it is thought that the absorption of fertilizer components such as potassium is promoted through the activation of the cell membrane proton pump by auxin, and the elongation growth of the plant is induced. On the other hand, in Comparative Example 1, in which only water was sprayed, and in Comparative Example 2, in which the comparative liquid containing stearic acid, which is a linear saturated fatty acid, was sprayed, no increase in the auxin content in the applied plants was observed. In Example 2, in which the fertilizer component absorption enhancer of the present invention was applied together with commercially available fertilizer components, the auxin content in the plant was further increased. Therefore, by using the fertilizer component absorption enhancer of the present invention together with plant fertilizer components, it is possible to provide a plant fertilizer having an excellent plant growth-promoting effect with enhanced absorption efficiency of the fertilizer components.
