Seeds of two cultivars or water convolvulus, 'Pingtung Green Stem' (pointed leaf) and 'White Stem' (broad leaf), were classified into four fractions, which were 41.0, 4.0, 4.5 and 4.5 mm, by standard round sieves, Unsorted seeds were served as control Vigour of different fraction seeds were tested by topographical tetrazolium test. Emergence and seedling growth of different fraction seeds were tested at constant temperature of 300C in a growth cabinet and in the field with different sowing dates respectively. The results indicated that the time to seed emergence, emergence percentage and seedling growth were not significantly influenced by seed size. Similar results were obtained in the field experiment. Seed size did not affect time to seed emergence, emergence percentage and seedling growth of these two cultivars under field condition.
