*4.10. Chlorophyll Content of Cassava Leaves*

The chlorophyll content of the cassava leaves was quantified as previously described [54]. The harvested leaves were ground in 80% acetone. After centrifugation, the absorbance of OD<sup>647</sup> and OD<sup>665</sup> of the supernatant solution was detected by a microplate system (Infinite M200 Pro, TECAN, Hombrechtikon, Switzerland). The total chlorophyll content was 17.90 × OD<sup>647</sup> + 8.08 × OD665.
