The question is in another way.

What is the relationship between SPAD chlorophyll value and Chlorophyll a, b and total Chl?

For example, if the lettuce plant has high SAPD content value that means the Chlorophyll must be high?? or any relationship with other chlorophyll components??

SPAD index and chlorophyll content are directly related.
