Description/Abstract:
PROBLEMS RELATED TO THE COLONIZATION OF CORAL ATOLL BEACHES, FROM SEED DISPERSAL TO THE ESTABLISHMENT OF THE SEEDLINGS, WERE STUDIED IN SIMU LATED ENVIRONMENT. CORAL SAND AND SEA WATER WERE USED IN GERMINATION A ND SALT TOLERANCE TESTS, AND THE NUTRITIONAL REQUIREMENTS WERE INVESTI GATED IN SOLUTIONS APPROXIMATING THE COMPOSITION OF RONGELAP GROUND WA TERS. SALINITY CONDITIONS ON RONGELAP ATOLL WERE STUDIED THROUGH SOIL, GROUND WATER AND RAIN WATER SAMPLES. ACCUMULATION OF SODIUM AND CESIU M IN INTACT PLANTS WAS STUDIED WITH RADIOACTIVE ISOTOPES. M IN INTACT PLANTS WAS STUDIED WITH RADIOACTIVE ISOTOPES. SEED DISPERS AL. ANATOMICAL STRUCTURE OF SCAEVOLA AND MESSERSCHMIDIA FRUITS FACILIT ES THE DISPORSAL OF THE SEEDS BY SEA CURRENTS. FRUITS OF THESE SPECIES FLOATED IN SEA WATER FOR 120 DAYS WITHOUT A LOSS IN GERMINATION CAPAC ITY. SEEDS FLOATED IN SEA WATER GERMINATED ONE TO TWO WEEKS SOONER THA N DRY SEEDS WHEN PLACED IN NON-SALINE SOIL.
