摘要
Ｂａ（ＯＨ）２溶液在０．０００５～０．００４５Ｎ范围内、浓度（Ｎ）和电导率（μΩ－１成直线相关ｒ＝０．９６２１５３＊＊。根据Ｂａ（ＯＨ）２＋ＣＯ２→ＢａＣＯ３↓＋Ｈ２Ｏ这一当量反应，植物组织呼吸释放的ＣＯ２量，可由Ｂａ（ＯＨ）２待测液下降的电导率显示，用此电导率查Ｂａ（ＯＨ）２标准曲线浓度，可计算出呼吸速率ＣＯ２ｍｇ／ｇ·ｈ。
a(OH) 2 solution appeared linear relation with conductivity values, when the solution concentration is within 0 0005_0 0045N (r=0 962153 ** ).According to formula Ba(OH) 2+CO 2BaCO 3↓+H 2O,respiratory rate of plant tissue be expressed with conductivity of Ba(OH) 2 solution reduction. The respiratory rate can be obtained through the change of conductiivity values and standard curve of Ba(OH) 2 solution.
