Synthetic Seeds of Two Aquatic Plants

Aquatic ornamentals are generally used for aquarium decorations because of their colored foliage and attractive appearance. Cryptocoryne species are popular due to their easy growth and capacity to thrive for a long time. Cryptocoryne lutea is an excellent mid-ground plant with bright green or bronzy oblong leaves. Rotala rotundifolia is characterized by a rapid growing stem and beautiful growth pattern; for these features it is considered the ideal aquarium plant for beginners. These aquatic plants are usually easily propagated by cutting, but previous studies allowed to develop a suitable protocol of micropropagation. A renewed interest is due to the possibility to obtain synthetic seeds by in vitro-derived propagules to be used in aseptic or in ex vitro conditions for propagation system.
