摘要
将山丹鳞茎在4℃分别冷藏处理15、30、45、60d和冷藏处理45d+赤霉素200mg/L,研究低温处理时间和赤霉素对鳞茎解除休眠与花期调控的影响。结果表明:冷藏时间越长,鳞茎解除休眠需要的时间越短。赤霉素处理相比于未施用赤霉素处理,鳞茎解除休眠需要的时间缩短3d,发芽到现蕾的时间缩短5d。赤霉素处理有助于山丹鳞茎快速解除休眠,提前开花。
Effects of chilling and gibberellin on release dormancy and flowering regulation of Lilium pumilum were studied by bulbs of Liliurn pumilurn which were refrigerated for 15,30,45,60 days at 4℃ and for 45 days at 4℃ combined treatment with 200 mg/L gibbereUin. The results showed that the longer refrigerating, the shorter times of the bulb dormancy required. Treatment with 200 mg/L gibberellin compared to the control, 3 days could be shorten for the time of release dormancy,5 days could be shorten from building stage to squaring stage. The bulbs of Lilium purnilum treated with gibberellin could accelerate the bulbs to release dormancy,bloom earlier.
