Abstract
|
|
|
Contents of proline and chloride in halophytes were 80-1700 ㎍/gfw and 0.13-0.45 mM/gfw respectively. The content of proline was inversely proportional to that of chloride.
Rhizomes of Phragmites communis Trin, a halophyte, were grown in non-saline medium and then taken to saline treatment for one or two weeks. Growth of P. communis was inhibited when salinized with 0.25M NaCl. Total nitrogen decreased and alcohol soluble nitrogen and proline increased when growth was retarded. The quantity of Fraction I protein decreased at 0.25M NaCl treatment. The accumulation of proline at high concentration in P. communis suggested that it might play a role in osmotic adjustment.
