Embodiment 1

[0026] The selection method of the excellent individual plant of 4-terpineol type Melaleuca mellifera comprises three steps:

[0027] (1) Single plant primary selection

[0028] Individual plants with larger crowns and dense branches and leaves were initially selected from the Melaleuca forest that had not been felled for 4 consecutive years, and the individual plants were numbered in sequence. Determining the oil yield and essential oil components of branches and leaves after removing branches larger than 1cm and withered branches and leaves, the selected oil yield is >1.0%, the content of 1,8-cineole in the essential oil is 39.0% The selected plants are regarded as the superior plants in the primary selection, and the number of the superior plants is the same as the serial number compiled during the primary selection, and the superior plants in the primary selection are treated with flat stubble.

[0029] (2) Breeding and planting

[0030] Cut off the germination strips of...

Embodiment 2

[0036] The selection method of the excellent individual plant of 4-terpineol type Melaleuca mellifera comprises three steps:

[0037] (1) Single plant primary selection

[0038] Individual plants with large crowns and dense branches and leaves were initially selected from the Melaleuca forest that had not been felled for 5 consecutive years, and the individual plants were numbered in sequence. Determining the oil yield and essential oil components of branches and leaves after removing branches larger than 1cm and withered branches and leaves, the selected oil yield is >1.0%, the content of 1,8-cineole in the essential oil is 39.0% The selected plants are regarded as the superior plants in the primary selection, and the number of the superior plants is the same as the serial number compiled during the primary selection, and the superior plants in the primary selection are treated with flat stubble.

Embodiment 3

[0046] The selection method of the excellent individual plant of 4-terpineol type Melaleuca mellifera comprises three steps:

[0047] (1) Single plant primary selection

[0048] Individual plants with large crowns and dense branches and leaves were initially selected from the Melaleuca forest that had not been felled for 6 consecutive years, and the individual plants were numbered in sequence. Determining the oil yield and essential oil components of branches and leaves after removing branches larger than 1cm and withered branches and leaves, the selected oil yield is >1.0%, the content of 1,8-cineole in the essential oil is 39.0% The selected plants are regarded as the superior plants in the primary selection, and the number of the superior plants is the same as the serial number compiled during the primary selection, and the superior plants in the primary selection are treated with flat stubble.

Abstract

The invention discloses a selection method for a fine individual plant of 4-terpilenol type cajeput. According to the selection method, a cajeput plant is subjected to individual plant primary selection, breeding and tending and individual plant secondary selection to obtain the fine individual plant of which the content of 1,8-eudesmin is less than 3.0 percent and the content of the 4-terpilenol is more than 39.0 percent in essential oil. The quality of the produced essential oil is superior to the international standard of the like products. The selection method disclosed by the invention is simple and can be used for obtaining high oil yield of branches and leaves.

Description

technical field [0001] The invention belongs to the combined field of biotechnology and chemical utilization, and in particular relates to a method for selecting excellent individual plants of 4-terpineol type Melaleuca mellifera. Background technique [0002] Tea tree oil is the essential oil obtained by steam distillation from the leaves and twigs of the evergreen shrubs to the small trees of the Myrlaceaca genus Melaleuca (Melaleuca) native to eastern Australia. Spectrum bactericidal and antibacterial effects, widely used in pharmaceuticals, daily chemicals, food, spices and other industries. Current plant sources of Melaleuca oil include: Melaleuca alternifolia, Melaleuca bracteata, Melaleuca quinquenervia, Melaleuca ericifolia, green Melaleuca viridiflora (Melaleuca viridiflora), Melaleuca leucadendron (Melaleuca dissiliflora), Melaleuca linariifolia (Melaleuca linariifolia), etc., the main components and output The oil rate and the biomass of branches and leaves were...
