A method for propagating golden iron locks by cuttings

Abstract

The invention discloses a cutting propagation process of psammosilene. The process comprises the following steps: firstly carrying out re-cultivation on the tender stems of the psammosilene female parent; taking a pair of stems with axillary buds and leaves as a cutting propagation unit when the tender stems grow to 3-8cm and cutting all cutting slips; inserting the cut materials on a barbed wire in sequence to ensure that the stem parts at the lower ends of the cutting slips are soaked in culture solution; taking out the cutting slips when the soaked stems are expanded and inserting the cutting slips on a preconfigured and disinfected seedbed; timely removing the flower buds when lateral buds sprout and flower buds appear. The cutting propagation process of psammosilene is capable of remarkably accelerating the propagation speed of the psammosilene, shortening the seedling growing period, improving the germchit quality, providing technical guarantee for accelerating the germchit production of the psammosilene and bringing significance to the biodiversity protection.

Description

technical field [0001] The invention relates to a method for propagating golden iron locks by cuttings, and belongs to the field of biotechnology. Background technique [0002] Jintiesuo is a plant of the genus Jintiesuo in the caryophyllaceae family, Jintiesuo ( Psammosilene tunicoides W. C. Wu et C. Y. Wu), also known as Dudingzi, Kunming Adenophora, Centipede Seven, Duyeqi, etc., are mainly distributed in Yunnan, Sichuan, Guizhou and parts of Tibet. It is a single-species genus unique to China, and it is an important material for studying the taxonomy and evolution of Caryophyllaceae plants. Folk medicine has a long history. It was first recorded in "Southern Yunnan Materia Medica", and then included in the 1977 edition of "The Pharmacopoeia of the People's Republic of China". It has the functions of dispelling blood stasis, reducing swelling, draining pus, and stopping bleeding. Wound bleeding, swelling and pus drainage, etc., are now common raw materials for ph...

Problems solved by technology

After reviewing the literature, relevant scientific researchers have used Agrobacterium rhizogenes to induce hairy roots in Jintiesuo and achieved certain results; they have carried out corresponding research on the organic components of Jintiesuo, blood components, and rapid propagation of tissue culture and achieved corresponding results. Jintiesuo uses cuttings with leaves and tender stems, which has not been reported yet. In order to improve the construction of the rapid propagation system of Jintiesuo cuttings, this study proposes for the first time that under the condition of artificial intervention, the cuttings of young stems of Jintiesuo can be used for rapid formation of new plants. So as to solve the problem that Jin Tiesuo uses seeds to propagate slowly and is greatly affected by environmental factors
