Effect of Ri and Bj on the relative chlorophyll content (RCC) of plant leaves. A Comparison of relative chlorophyll content (RCC) through time in mungbean leaves under four treatments. Color of four treatments, grey: control; green: Ri treatment; blue: Bj treatment; purple: Ri + Bj treatment. B Relationship between RCC and total nodule weight. SPAD: values measured by the Soil Plant Analysis Development (SPAD) chlorophyll meter. Light green: 4 weeks post-inoculation (wpi); green: 5 wpi; dark green: 6 wpi. Lines are the linear regression lines. The shades represent 95% confidence interval (CI) of the line values
