Large-scale breeding method of Borneol Cinnamomum camphora

Abstract

The invention relates to a large- scale breeding method of Borneol Cinnamomum camphora. The method comprises the following steps of: breeding a plantlet obtained through unique cuttage treatment by utilizing a current-growth lignified branch of strongly disease-resistant, no pest and disease damage and grown-up seed tree for about one year, acclimatizing, subculturing and propagating a sterile material after obtaining the sterile material with the current germinal sprout as an explant, secondly carrying out strong seeding rootage cultivation, and finally cultivating seeding in a greenhouse. According to the method disclosed by the invention, induced, propagated, strengthened and rooting culture mediums are optimized and improved, the stable growth of the sterile material can be effectively ensured, the sizes of sprouts are uniform, vitrification or defoliation of a tissue culture seedling can be avoided, the strong tissue culture seedlings can be obtained for sure, the repeatability is strong, an acclimation period and a subculture period are stable, a browning situation is reduced, a propagation coefficient is improved, the survival rate of planting in a greenhouse is improved, asubculture block mass cutting method determines the growth and the propagation coefficient of later-stage materials and can meet requirements of large-scale production.

Description

technical field [0001] The invention relates to the technical field of plant propagation, in particular to a production method for large-scale propagation of Cinnamomum camphora (L.) Sie. Background technique [0002] Borneo camphor is a plant of the genus Lauraceae, an evergreen tree. Originating in the Sumatra Islands of Indonesia, it is a precious medicinal spice tree species and landscaping tree species rich in aromatic oils, and is also an important chemical raw material and natural plant resource of borneol (D-borneol) (natural borneol is a natural plant resource) It is also an effective transdermal accelerator, which has anti-inflammatory, anti-myocardial ischemia, antibacterial, analgesic, and antiseptic effects) (Cheng Biqiang et al., 1997). For a long time, the development and utilization of borneol camphor has been mainly based on the extraction of essential oils. Over-harvesting has caused serious damage to its resources, especially the excellent tree resources ...
