Pro Experimentis


A method of estimating the photosynthetic rate of soybean leaves using an oxygen electrode is presented. The procedure is rapid, requires small samples and compares favourably with estimates by other techniques. Light saturation occurs at 1200 μE·m−2·sec−1. The apparent Km for HCO 3 is 3.2 mM at pH 7.6.
