 note = {We investigated the effects of night temperature and day length on the flowering of eight Alstroemeria species. When Alstroemeria plants were grown with a night temperature of 15℃ and a natural day length, the date of the first flower significantly varied ; i.e., the first flower appeared in March for A. pelegrina and A. magenta, April for A. pulchra, A. magnifica and A. aurea，May for A. ligtu and A. versicolor，and June for A. hookeri. The floweringperiod was 70 to 110 days for A. pelegrina, A. magenta and A. aurea and about 30 days for A. ligtu, A. pulchra, A. versicolor and A. hookeri. When the plants were grown with night temperatures of 5, 10 and 15℃ and a natural day length, the number of flowering shoots increased with the low night temperature conditions. Low night temperatures delayed flowering conspicuously for A. pelegrina，A. magenta，and A. aurea. On the other hand, night temperature had no effect on flowering time for A. ligtu，A. versicolor, or A. hookeri. Flower stem length was shorter under low night temperature conditions for A. ligtu，A. magenta，A. pelegrina，A. pulchra and A. magnifica. A long day length (16 hours) promoted flowering in all species. This tendency was more noticeable in A. ligtu, A. magenta, A. versicolor, A. hookeri and A. magnifica than in A. aurea, A. pelegrina and A. pulchra. Long days also increased flower production in A. ligtu，A. pulchra，A. versicolor, A. aurea and A. hookeri, and increased flower stem length in A. magenta，A. pulchra，A. versicolor, A. hookeri and A. magnifica.},
