Summary

THE POSSIBILITY OF USING SEED ADENOSINE TRIPHOSPHATE (ATP) CONTENT AS AN INDICATOR OF SEED VIGOR WAS STUDIED. SEEDS OF CORN (ZEA MAYS L.), CUCUMBER (CUCUMIS SATIVUS L.), ONION (ALLIUM CEPA L.) AND RADISH (RAPHANUS SATIVUS L. ) WITH SEED MOISTURE CONTENTS OF 5, 10, 15, 20 OR 25% WERE STORED AT TEMPERATURES OF 263, 278, 288, 298 OR 308 K (-10, 5, 15, 25 OR 35 C) FOR 0, 2.5, 5, AND 10 MONTHS. VIABILITY WAS LOST IN MOST SEEDS AFTER 2.5 MONTHS AT 298-308 K AND HIGH MOISTURE (20-25%) CONTENTS. SEED AT 278 K AND 5% MOISTURE MAINTAINED THE HIGHEST VIABILITY AND SEEDLING VIGOR. LOW TEMPERATURE (263 K) AND HIGH SEED MOISTURE LEVELS (20-25%) REDUCED GERMINATION AND VIGOR OF RADISH SEED. SEED ATP CONTENT DID NOT CORRELATE WITH REDUCED GERMINATION OR VIGOR IN ANY SPECIES.
