Embodiment 1

[0034] The present embodiment is a kind of ginger flower breeding method based on leaf-stem cryptobud promotion provided by the present invention, comprising the steps:

[0035] (1) material selection: choose the top that has pumped out inflorescences, the ginger flower leaf stem that the flowering period has passed, and the diameter of the ginger flower leaf stem is 10mm;

[0036] (2) Aseptic treatment of materials: the leaf sheath of the ginger flower leaf stem described in step (1) is peeled off layer by layer to the last layer, cut to a segment in a sterile environment, and the length is 4cm, and then put into mass concentration Soak in 75% alcohol solution for 1min, take out and dry, and peel off the last layer of leaf sheath to obtain the segment exposing the hidden bud;

[0037](3) Hormone treatment: put the section of exposed cryptobud described in step (2) into the aseptic solution that the benzylaminoadenine of 50mg / L and the plant growth regulator of 10mg / L are mixe...

Embodiment 2

[0041] The present embodiment is a kind of ginger flower breeding method based on leaf-stem cryptobud promotion provided by the present invention, comprising the steps:

[0042] (1) material selection: choose the top that has pumped out inflorescences, the ginger flower leaf stem that the florescence has passed, and the diameter of the ginger flower leaf stem is 11mm;

[0043] (2) Aseptic treatment of materials: the leaf sheath of the ginger flower leaf stem described in step (1) is peeled off layer by layer to the last layer, cut to a segment in a sterile environment, and the length is 6cm, and then put into mass concentration Soak in 75% alcohol solution for 1min, take out and dry, and peel off the last layer of leaf sheath to obtain the segment exposing the hidden bud;

[0044] (3) Hormone treatment: putting the section of exposing cryptobuds described in step (2) into a sterile solution mixed with benzylaminoadenine at a concentration of 50 mg / L and a plant growth regulato...

Abstract

The invention relates to a hedychium coronarium breeding method based on leaf stem resting bud germination promotion, belonging to the technical field of seedling breeding in the gardening field. According to the hedychium coronarium breeding method based on leaf stem resting bud germination promotion, leaf sheaths are peeled off to expose resting buds so as to facilitate germination of the resting buds; temperature and humidity are further controlled; the resting buds are promoted to germinate into small rhizomes under a high-density condition by means of segment nutrition under sterile and matrix-free conditions; and the small rhizomes are sown into a seedbed. The method provided by the invention defines the maturity and the thickness (the diameter of a leaf stem) of an optimal materialand the required ranges of the temperature, humidity and hormone ratio for promoting germination of the resting buds of leaf stems, so the propagation manner with the resting buds of the leaf stems ofhedychium coronarium with a variety of Hanyue as a material source is high and stable in seedling rate, simple and convenient in operation, low in labor cost and applicable to large-scale propagation.

Description

technical field [0001] The invention relates to a ginger flower breeding method based on leaf-stem cryptobud promotion, and belongs to the technical field of seedling breeding in the field of horticulture. Background technique [0002] The propagation methods of Gingeria plants mainly include seed propagation, rhizome propagation and tissue culture propagation. Due to the fact that the seedlings propagated by seeds are often characterized by segregation and the cost of tissue culture propagation is relatively high, at present the production is mainly propagated by rhizome ramets. Due to the limited number of rhizomes, it is urgent to find a propagation method with a wider source of material. Gingeria plants have two types of stems, leaf stems in addition to rhizomes. Most people, including some authoritative chronicles, think that the leaf stems of Gingeria plants are pseudostems. For example, the English version of Flora of China translates the leaf stems of Gingeria plan...
