Abstract
|
|
|
This experiment were conducted to investigate the bolting response of radish (cv. Jinjudaipyung) and Chinese cabbage (cv. Bombaechu) as influenced by the bolting habit of mother plants and the seed size and maturity. The seeds harvested in various ways were vernalized for 0, 5, and 10 days at 5℃ and plants were grown under continuous illumination (6,500 lux) at 25℃.
The results are summarized as follows.
1. The progenies from late bolting mother plants showed late bolting habit (more leaves per plant). It appears that this late bolting habit is associated with the lower photosensitivity in this population.
2. The progenies from unscreened population showed wider range of leaf number per plant, indicating greater variation in bolting habit.
3. The radish seeds harvested at immature stages exhibited late bolting habit indicating the presence of lower photosensitivity in immature seeds.
