Abstract:
Owing to climate influence, mean daily temperature in north China differs greatly from that of the southern regions during the same season. The introduction of Fritillaria thunbergii to Beijing for cultivation was hampered by delayed emergence of seedling and a shortened period for their growth, resulting in degeneration with the underground bulb becoming smaller year after year. With forcing culture as described in this paper, the emergence of seedling came earlier and growth period prolonged. The blossom and fruit became normal.By combining the method with formalin treated seed, diseases and pest index of the bulb were reduced distinctly and the yield increased with increased proportion of larger bulb year after year.
