Method for quickly inducing bulblet by lily bulb scale slice

Abstract

The invention provides a method for quickly inducing bulblet by lily bulb slice, which comprises the steps of seed ball low-temperature dormancy breaking treatment and scale disinfection treatment. The method is characterized in that the scale disinfection comprises the following treatments: scale pre-culture, scale slicing, bulblet inducing culture, bulblet culture, treatment before bulblet bottle-out and field setting. Each scale can produce 20 to 30 bulblets, each seed ball can produces more than 300 bulblets, the method not only can produce bulb-let with high yield and high efficiency rapidly, but also can form single bulblet directly and does not have the multi-pistil problem that the bulb-let is induced from adventitious bud; and the bulblet can be formed by direct inducing culture, thus reducing the process and the time for the callus tissues and the adventitious bud which require at least two times of secondary change over to form bulblet in the prior art, and simultaneously avoiding the mutation of the bulblet induced from bulblet. The bulblet induction and culture are performed in darkness, thereby effectively saving the energy source.

Description

technical field [0001] The invention relates to a method for efficiently producing lily bulblets, belonging to the technical field of plant cultivation. Background technique [0002] Lily (Lilium spp.) is a plant of the genus Lilium (Lilium) in the family Liliaceae. It is an important bulbous flower in the world. It has the characteristics of beautiful flower shape, bright color and pleasant fragrance, and is deeply loved by people. However, the bulbs used in my country's current production mainly rely on imports, and 150 million bulbs are needed every year. In recent years, the state and various provinces have supported the localization of lily bulbs, and a small amount of domestic bulbs have been put on the market. According to statistics, there were about 25 million domestic bulbs in 2008, which is less than the annual demand for lily bulbs in my country. There is a considerable gap. Due to the immature bulb breeding technology in our country, and the long breeding cycle...

AI Technical Summary

Problems solved by technology

[0004] In view of the low propagation efficiency of scale cuttings in the prior art, the tissue culture rapid propagation technology not only has a low seed rate, but also produces small bulbs with limited parts, mainly callus and adventitious buds, and there are many processes for forming small bulbs. It takes a long time and is prone to problems such as variation. The present invention provides a method for quickly inducing small bulbs by using lily scale slices to quickly and mass-produce lily bulblets with high quality and low cost to meet market demand.
