Parts used
Hygrophila polysperma is a versatile ornamental aquatic plant that is recognized for its ability to change leaf color to a pinkish hue under high light conditions. Beyond its aesthetic appeal, this species serves as a valuable medicinal plant and a bioindicator for detecting algae and toxicity. Scientific research has demonstrated that the leaf of this plant can function as a potent explant for in vitro regeneration. By utilizing specific hormone combinations like Kin, TDZ, and IBA, researchers can successfully induce adventitious shoot regeneration from these leaf tissues. This process ultimately allows for the mass production of healthy plantlets that can be effectively acclimatized for aquarium use.
