PROBLEM TO BE SOLVED: To provide a carbon dioxide absorption amount acquisition device, a carbon dioxide absorption amount acquisition method, and a program which acquire the carbon dioxide absorption amount of a plant with high-precision without inhibiting growth of the plant.SOLUTION: A weight measuring part 103 measures the weight of a plant at a plurality of time point over a plurality of days within a period of time. A weight acquisition part 105 acquires the weight measured at the time point when the weight of the plant is maximum in each one of a day different from each other among the weights measured at a plurality of the time point by the weight measuring part 103. A carbon dioxide absorption amount acquisition part 106 acquires the carbon dioxide absorption amount of the plant on the basis of the difference of the weight acquired by the weight acquisition part 105.SELECTED DRAWING: Figure 2COPYRIGHT: (C)2016,JPO&INPIT【課題】植物の生育を阻害することなく、高精度の植物の二酸化炭素吸収量を取得する二酸化炭素吸収量取得装置、二酸化炭素吸収量取得方法及びプログラムを提供する。【解決手段】重量測定部103が、複数の日に亘る期間内の複数の時点における植物の重量を測定する。重量取得部105は、重量測定部103が複数の時点において測定した重量の中から、互いに異なる日のそれぞれにおいて、植物の重量が極大となる時点で測定された重量を取得する。二酸化炭素吸収量取得部106は、重量取得部105が取得した重量の差分に基づいて、植物の二酸化炭素吸収量を取得する。【選択図】図2
