Problems solved by technology

[0004] At present, there are also a small number of methods to quickly promote the formation of A. sinensis in production, such as mechanical trauma and smearing of chemical reagents on the trunk, etc., but the efficiency of these methods in the past is generally not high, and the effect is limited to a small area of ​​the treated part of the trunk. The output of Agarwood is small, and it is impossible to realize large-scale standardized and commercial production. There is no report on the method of quickly promoting the whole body of Agarwood.

Embodiment 1

[0027] In June, 5-year-old saplings were selected as the material, and 4 holes with a diameter of 1.00 cm and a horizontal depth of about 1 / 2 of the trunk were drilled with an electric drill at an angle of 90° at 1.00m of the trunk of each tree at a 35° downward angle. The vertical distance between the four holes is 30.00cm to form a "four-hole helical structure", and then a 5.00mL syringe is used to inject methyl jasmonate (MeJA) with a concentration of 0.10% into the holes to inject 2.00% ethylene Lithium (ETH), salicylic acid (SA) and abscisic acid (ABA) were used as the control group, and about 100.00 mL was injected into each tree for each treatment. At this time, the leaves of the tree body showed a severe wilting state. After the injection is complete, seal the hole with plasticine. After 6 months of treatment, the tree body was harvested and dissected to measure the size of the discoloration range. The reddish-brown xylem is Agarwood. After being treated with methyl j...

Embodiment 2

[0032] Taking the injection in June as the test group, and taking the injection in January, March and September as the control group, select 5-year-old Akiras saplings as materials, and use an electric drill to incline at 1.00m of the trunk of each tree at an angle of 90°. Drill 4 holes with a diameter of 1.00cm and a horizontal depth of about 1 / 2 of the trunk at a downward angle of 35°. The vertical distance between the four holes is 30.00cm to form a "four-hole helical structure". The injection concentration is 0.10% methyl jasmonate (MeJA), and each tree is injected with a total of about 100.00 mL. After the injection is complete, seal the hole with plasticine. After 6 months of treatment, the tree body was harvested and dissected, and the reddish-brown xylem was Agarwood. The results showed that the average longitudinal discoloration area injected in June was 692.60cm 2 , while the longitudinal discoloration areas of the control group injected in January, March and Septe...

Embodiment 3

[0034]Select a 6-year-old young tree as a material, and use an electric drill to drill 4 holes with a diameter of 1.00 cm and a horizontal depth of about 1 / 2 of the trunk at an angle of 90° at every 90° angle of the trunk of each tree. The vertical height distance of each hole is 30.00cm, forming a "four-hole helical structure". Another part of the sample is only injected into one hole, and the single-hole injection is used as the control group, and then injected into the hole with a 5.00mL syringe at a concentration of 0.10%. A total of about 100.00 mL of methyl jasmonate (MeJA) was injected per tree for each treatment. At this time, the leaves of the tree body showed a severe wilting state. After the injection is complete, seal the hole with plasticine. After 6 months of treatment, the tree body was harvested and dissected, and the reddish-brown xylem was Agarwood. The results showed that the horizontal and vertical discoloration areas of the test group injected with the "f...

Abstract

The invention discloses a method for rapidly promoting whole-body agilawood formation of aquilaria sinensis, and belongs to the technical field of wood science. By means of the method, almost whole-body (whole trunks and large-diameter branches) of xylem of a tree body is subjected to reddish brown color change, and that the oil content and composition of the color-changing xylem reach the level of natural agilawood is detected. The method is simple in process and convenient to operate, selected induction reagents are natural and free of pollution, the application method is scientific and novel, the induction effect is remarkable, whole-body agilawood formation of the tree body is basically achieved, consumed time is short, whole-body agilawood formation of the aquilaria sinensis can be rapidly promoted within a short time, the method can be used for large-scale standardized and commercial production, the contradiction between the supply and demand market of the agilawood can be effectively relieved, protection, development and utilization of aquilaria sinensis resources are facilitated, and important economic, social and ecological benefits are achieved.

Description

technical field [0001] The invention belongs to the field of biotechnology, and relates to a method for rapidly promoting the aroma formation of arborina chinensis throughout the body, in particular to a method for rapidly promoting the aroma formation of arborina chinensis throughout the body by using a plant growth regulator. Background technique [0002] Aquilaria sinensis (Lour.) Spreng. (Latin scientific name: Aquilaria sinensis (Lour.) Spreng.) is a kind of tropical and subtropical evergreen tree. It is the main tree species producing agarwood. It is a rare precious medicinal plant in the world. It is a national second-class protected plant and an internationally protected tree. 5-18 meters high, bark dark gray, almost smooth, fibers tough; branchlets cylindrical, wrinkled, sparsely pilose when young, then gradually shedding, glabrous or nearly glabrous, sometimes absent. Baimuxiang is mainly produced in Hainan, Guangdong, Guangxi, Fujian, and Yunnan. Agarwood heartw...
