Maturity, tobacco leaves reach maturity in the field and after modulation.
Mature, tobacco leaves have just reached maturity in the field, biochemical changes are insufficient or improper modulation, and post-ripening is not enough.
Immature, immature or improper modulation of tobacco leaves in the field, and poor maturity of tobacco leaves.
False maturity means that the leaf foot looks mature, but it has not reached the real maturity in essence.
Overripe refers to the tobacco leaves harvested in the field.
