What are halophytes give one example?
halophyte A plant that can tolerate a high concentration of salt in the soil. Such conditions occur in salt marshes and mudflats. Examples of halophytes are mangrove trees (see mangrove swamp), thrift (Armeria), sea lavender (Limonium), and rice grass (Spartina).
What are halophytes also called?
A halophyte 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 spray, such as in saline semi-deserts, mangrove swamps, marshes and sloughs and seashores.
How did halophytes evolve?
Halophytes (and other edaphic endemics) generally arose through colonization of habitats in severe disequilibrium by pre-adapted individuals, rather than by gradual adaptation from populations of ‘glycophytes’.
Which of the following plants are examples of halophytes?
Examples of halophytes are mangrove trees (see mangrove swamp), thrift (Armeria), sea lavender (Limonium), and rice grass (Spartina). Compare hydrophyte; mesophyte.
Is mangrove a Halophytic?
(2) Mangroves are obligate halophytes, i.e. salt is necessary for their growth. Mangroves cannot survive in freshwater permanently and salt water is a physiological requirement. Mangroves have the ability to absorb Na + and Cl – rapidly and preferentially under low-salinity conditions.
Which germination is a unique feature of Halophytic plant?
However halophytes exhibit an interesting mechanism to cope with salt stress. Many halophytes produce heteromorphic seeds, which have different dormancy and germination behavior under saline conditions. This characteristic is related to the structural and physiological differences among heteromorphic seeds.
What is a Halophytic plant?
Halophytes are plants which naturally survive in salt-contaminated environments and can tolerate salinity concentrations as high as 1 M NaCl (Flowers and Colmer, 2008; Kumari et al., 2015). About 1% of the total flora of the world (both dicots and monocots) are halophytic plants.
Which of the following plant is the best example of halophytes?
What can halophytes be used for in the future?
Beside their potential to become cash crops, halophytes can be used in future also as model plants for the development of salt resistant crops from current non-salt tolerant conventional crops. Investigations of salt tolerant mechanisms of halophytes could provide critical clue to improve salt tolerance.
How are halophytes and glycophytes related to each other?
Plants are classified into glycophytes (salt-sensitive plants) and halophytes (salt-loving plants) based on their tolerance to salinity. Halophytes are plants which naturally survive in salt-contaminated environments and can tolerate salinity concentrations as high as 1 M NaCl ( Flowers and Colmer, 2008; Kumari et al.]
How many species of halophytes are there in the world?
The number of halophyte species is estimated to range from 2000 to 3000 ( Sabovljevic and Sabovljevic, 2007) and majority of them belong to angiosperms. During 1980s, James Aronson compiled a comprehensive database of 1554 halophyte species, termed as HALOPH ( Aronson and Whitehead, 1989 ).
How is the rhizosphere of a halophytic plant used?
The rhizosphere of halophytic plants serves as a reservoir for various groups of salt-tolerant rhizobacteria that could enhance the growth of crops under salinity stress ( Jha et al., 2012, 2015; Shukla et al., 2012; Bharti et al., 2013; Ramadoss et al., 2013; Goswami et al., 2014; Sharma et al., 2016; Yuan et al., 2016 ).
