The invention discloses a
detoxification method of lily bulbs, wherein the method comprises the following steps: (1) placing the lily bulbs for 40-50 days at the temperature of 3-8 DEG C; (2) selecting the lily bulbs having the
bud length of 4-8 cm, stripping outer-layer flakes, leaving bulbus discs with 3-5 inner-layer flakes, placing the bulbus discs into an
incubator, and preprocessing, wherein the preprocessing conditions comprise that the illumination intensity is 1500-2000
Lux, the temperature is 35-40 DEG C and the
processing time is 2-5 days; (3) selecting a normally growing bulbus disc, stripping a 0.4-0.7 cm stem tip, transferring into a differentiation culture medium, firstly, carrying out dark culture for 1-2 days at the temperature of 23-25 DEG C, then transferring into an illumination
incubator with the illumination intensity of 1500-2000
Lux and the illumination time of 12-16 h / d, heating up at a speed of 1-5 DEG C / d, rising the temperature to 35-45 DEG C, and then keeping the temperature and culturing for 35-45 days. Lily
bulb viruses are removed by combining heat treatment and
chemical treatment, the induction culture period is shortened, and the method also has the advantages of high detoxification rate, high value-added coefficient and the like, and provides a technical basis for culture of lily
virus-free plants and promotion of
virus-free culture research.
