Bulb storage temperature and duration influence flower quality and timing of Lycoris aurea.

摘要

The effects of bulb storage duration and temperature on the flowering of greenhouse-grown Lycoris aurea were assessed in two experiments. In 2004/05 lifted bulbs were stored at 22, 25 or 28 degrees C for 92 days, or non-lifted bulbs were stored at 25 degrees C for 0, 40, 60, 80 or 100 days. Increasing storage temperatures of lifted bulbs delayed flowering by up to seven days and increased stem length by greater than 150 mm. Storage durations of non-lifted bulbs of 40-60 days advanced the flowering date by up to 10 days, and had no effect on cut stem length and yield.
