Abstract

The invention discloses a virus-free tissue culture and rapid propagation method for OT type hybrid lily, and belongs to the technical field of plant tissue culture and rapid propagation. The method comprises: preparation of a culture medium, taking lily provenance bulb shoot tips as explants, and rapidly obtaining a large amount of virus-free tissue-cultured seedlings through steps such as induction, proliferation, bulb expansion culture, cold storage, transplanting, and virus detection. The present invention adjusts the formula of the culture medium, and adopts technologies such as secondary stem tip heat treatment for detoxification and induction culture, so as to directly induce bulb buds and / or rootless tissue cultured seedlings without going through the callus growth stage, thereby preventing the growth of seedlings. Sexual variation, shortening the induction culture period, has the characteristics of complete detoxification, high multiplication coefficient, low production cost, strong practicability, etc., and can be popularized and applied in the detoxification tissue culture production of lilies and other plants.

Description

technical field [0001] The invention relates to the technical field of plant tissue culture and rapid propagation, in particular to a method for virus-free tissue culture and rapid propagation of OT hybrid lilies. Background technique [0002] OT-type hybrid lily (Oriental×Trumpet Hybrid) is a hybrid series of Oriental Lily and Trumpet Lily / Aurelianos hybrid line. It is a perennial ornamental plant of Liliaceae, mainly used for cut flower cultivation. Its plant stem strength, disease resistance, heat resistance, salt and alkali resistance and other traits are obviously better than oriental lily, so it has a good market development prospect. In recent years, the production of cut lily flowers in my country has increased by more than 20% annually, but lily bulbs have always been dependent on imports from abroad. However, viral disease infection has caused serious degradation of lily species, which has brought huge economic losses to lily bulb producers around the world. There...
