For identification the dynamics of alterations in the chlorophyll content, the selection was carried out in three periods - the period before flowering, during the mass flowering phase and in the fruiting phase. Results showed that the total chlorophyll content in soy leaves is high during the flowering and fruiting phases, and then decreases in the ripening phase.

Merrill is one of the components of the chloroplast, which directly limit the most common crops in the world.
