1. In this experiment the author studied the relation between the Plant sue and occurrence of fasciated flower sta1k in connection With the seed production of Jpanese ever-season radish.
2. As the seed production of Japanese ever-season radish was
impossible in the area Where the annual mean temperature exceeds 18。C, the experiment was carried out at the Fu Show-Shan Farm ( 2,250 meter altitude, annual mean temperature 12.5。 C ), Taichung
prefecture during the period of January 1964 to June 1965. The radish seeds were sown on the first day of each month in 1964. The plants which were sown in January, February, and March bolted and flowered in the same year, others bolted and flowered in the next year.
3. It is note worthy that the occurrence of fasciated flower stalk were closely related with plant size, other words, the plants which were sown from April to September had large plant size at flowering season, and all of these plants bolted fasciated flower stalks. No seed was obtained from these plants. On the other hand the plants which were sown in January' February' March, October November, and December bolted flowered, and produced seeds normally in spite Of they were small in plant Size. The author also observed that early seeding resulted in higher production of seeds.
