In the early stages of growth, the sporophyte grows out of the prothallus, depending on it for water supply and nutrition, but develops into a new independent fern, which will produce new spores that will grow into new prothallia etc., thus completing the life cycle of the organism.
The prothallia of this species (or possibly a closely related species) are commonly cultivated as an aquarium plant, where it is known to aquarists as süsswassertang (German spelling: Süßwassertang). [3] It is often incorrectly spelled "subwassertang" due to the German eszett's similarity to the Latin 'B'. It is also called Loma fern or ...
The synthesis routes and their use as plant growth regulating agent were patented in the early 1980s by the German company Schering AG. Thidiazuron is taken up by the leaves and has a cytokinin-like behavior. [2] It causes leaves to lose weight in a controlled manner prior to harvesting, without affecting the growth and maturation of the plant.
The ratio of different plant growth regulators required to induce callus or embryo formation varies with the type of plant. [2] Somatic embryos are mainly produced in vitro and for laboratory purposes, using either solid or liquid nutrient media which contain plant growth regulators (PGR’s).
They are used to regulate the growth of cultivated plants, weeds, and in vitro-grown plants and plant cells; these manmade compounds are called plant growth regulators (PGRs). Early in the study of plant hormones, "phytohormone" was the commonly used term, but its use is less widely applied now.
Paclobutrazol (PBZ) is the ISO common name for an organic compound that is used as a plant growth retardant and triazole fungicide. [2] [3] It is a known antagonist of the plant hormone gibberellin, acting by inhibiting gibberellin biosynthesis, reducing internodal growth to give stouter stems, increasing root growth, causing early fruitset and increasing seedset in plants such as tomato and ...
