Abstract

The invention discloses root tip detoxification and rapid propagation technology for purple potatoes and belongs to the technical field of plant detoxification and tissue culture rapid propagation. The method comprises the following steps of: (1) preparing a culture medium; (2) performing root tip detoxification and rapid propagation; and (3) performing multi-reverse transcription-polymerase chain reaction (RT-PCR) synchronous and rapid detection on complex virus infection of a purple potato test tube plantlet or a test tube mini-tuber and the like. In the technology, each level of culture medium is adjusted according to the characteristic of the purple potato and conventional stem tip detoxification is changed into root tip detoxification so as to simplify operation process, avoid high pollution rate and improve working efficiency. Moreover, the technology has the advantages of good inoculant differentiation, high test tube plantlet propagation speed, complete detoxification, high mini-tuber growth vigor, monthly mini-tuber reproduction rate of 4 to 6 times and mini-tuber rooting rate and transplanting survival rate of over 98 percent. The technology can be popularized in regions which are suitable for the growth of purple potatoes.

Description

technical field [0001] The invention relates to the technical field of plant detoxification and tissue culture rapid propagation, in particular to a purple potato root tip detoxification and tissue culture rapid propagation technology. Background technique [0002] Purple potato is an annual crop of Solanaceae, native to Australia. Potato-shaped long oval, smooth skin, purple-black potato flesh, rich in anthocyanins, Vc, carotene, etc., with edible and medicinal functions. Anthocyanins are water-soluble pigments that exist in plants and belong to flavonoid compounds. They are the most direct, effective and safe free radical scavenger found in the scientific community to prevent and treat diseases and maintain human health. Its ability to scavenge free radicals It is 20 times of VC and 50 times of VE. Anthocyanins have a small molecular structure, and are the only substances that can clear free radicals and protect brain cells through the blood-brain barrier, and at the sam...
