Hint: It is a salt-tolerant plant that grows in soil or waters of high salinity, coming into contact with saline water through its roots or by salt sprays, such as in saline semi-deserts, marshes, sloughs, mangrove swamps, and seashores.
Complete answer
Viviparous germination may be a special sort of germination found in mangrove plants, which are salt-loving and are halophytes. Mangrove plants are found in marshy areas on the sea coast. The developed seeds still remain attached to the parent plant in viviparous germination.
The embryo grows out of the seed then out of the fruit and projects from it within the sort of a green seedling displaying the basis and therefore the hypocotyl.
Additional information
Major habitats where halophytes flourish include mangrove swamps, sand and cliff shorelines within the tropics, salt deserts and semi-deserts, the Sargasso Sea, mudflats and salt marshes, kelp forests and beds, salt lakes and salt steppes of the Pannonian region, wash fringes, isolated inland saline grasslands, and in places where people have caused salination.
One quantitative measure of salt tolerance (halotolerance) is the total dissolved solids in irrigation water that a plant can tolerate. Seawater typically contains 40 grams per liter (g/l) of dissolved salts (mostly sodium chloride).
At the opposite extreme, Salicornia bigelovii (dwarf glasswort) grows well at 70 g/l of dissolved solids and may be a promising halophyte to be used as a crop.
So the correct answer is ‘Viviparous germination’.
Note:
Adaptation to saline environments by halophytes may take the form of salt tolerance or salt avoidance. Plants that avoid the consequences of high salt albeit they sleep in a saline environment could also be mentioned as facultative halophytes instead of 'true', or obligatory, halophytes.
For example, a short-lived plant species that completes its reproductive life cycle during times (such as a rainy season) when the salt concentration is low would be avoiding salt rather than tolerating it.
