Embodiment 1

[0018] (1) Prepare substances and materials for promoting seed germination: light incubator, seeds of Dracaena saponifera, petri dish, fine sand, distilled water.

[0019] (2) Remove the seed coat from the Dracaena glabra seeds in step (1), wash them with an aqueous solution of detergent, rinse them with running water for 5 minutes in a beaker, and then put them in a refrigerator at 4°C for 5 days.

[0020] (3) Soak the seeds in step (2) with 1000-fold carbendazim solution for 12 hours, and rinse with distilled water twice.

[0021] (4) Soak the seeds in step (3) with different concentrations of naphthaleneacetic acid (NAA) for 6h, 12h, and 24h respectively, then rinse the soaked seeds twice with distilled water, and dry the surface of the seeds with clean filter paper Moisture, placed in a petri dish with a diameter of 12cm, with sterilized fine sand as a germination bed, and 30 seeds were placed in each petri dish. The concentrations of the naphthaleneacetic acid (NAA) are ...

Embodiment 2

[0024] (1) Prepare substances and materials for promoting seed germination: light incubator, seeds of Dracaena saponifera, petri dish, fine sand, distilled water.

[0025] (2) Remove the seed coat from the Dracaena glabra seeds in step (1), wash them with an aqueous solution of detergent, rinse them with running water for 5 minutes in a beaker, and then put them in a refrigerator at 4°C for 5 days.

[0026] (3) Soak the seeds in step (2) with 1000-fold carbendazim solution for 12 hours, and rinse with distilled water twice.

[0027] (4) The seeds in step (3) were treated with different concentrations of gibberellin (GA 3 ) soaking for 6 hours, 12 hours and 24 hours respectively, then rinse the soaked seeds twice with distilled water, blot the water on the surface of the seeds with clean filter paper, place them in a petri dish with a diameter of 12 cm, and use the sterilized fine sand For germination beds, place 30 seeds per dish. The gibberellin (GA 3 ) concentrations are ...

Embodiment 3

[0030] (1) Prepare substances and materials for promoting seed germination: light incubator, seeds of Dracaena saponifera, petri dish, fine sand, distilled water.

[0031] (2) Remove the seed coat from the Dracaena glabra seeds in step (1), wash them with an aqueous solution of detergent, rinse them with running water for 5 minutes in a beaker, and then put them in a refrigerator at 4°C for 5 days.

[0032] (3) Soak the seeds in step (2) with 1000-fold carbendazim solution for 12 hours, and rinse with distilled water twice.

[0033] (4) The seeds in step (3) were treated with the same concentration of naphthaleneacetic acid (NAA), gibberellin (GA 3 ) soaking for 6 hours, 12 hours and 24 hours respectively, then rinse the soaked seeds twice with distilled water, blot the water on the surface of the seeds with clean filter paper, place them in a petri dish with a diameter of 12 cm, and use the sterilized fine sand For germination beds, place 30 seeds per dish.

Abstract

A method for promoting the germination of Dracaena phoenix-leaves seeds, comprising the steps of: (1) getting mature and plump Dracaena phophyllum seeds, removing the seed coat, and successively using carbendazim, naphthaleneacetic acid (NAA), gibberellin (GA3) Soaking treatment at different times and different concentrations; (2) Place the treated seeds in the sterile fine sand in the petri dish, and put 30 seeds in each dish; (3) Set the temperature of the light incubator at 15 °C, 20 °C, 25 °C, and set different light time, the standard for seed germination is that the radicle breaks through the seed coat by 1mm and is considered as germination. A method for promoting seed germination of Dracaena phoenix leaf obtained by adopting the method of the invention has simple operation method and high seed germination rate. This method breaks the dormancy of Dracaena seeds and promotes their germination, provides technical support for accelerating the breeding of D. In order to provide more high-quality materials for the medical extraction of "dragon's blood" and further meet market demand.

Description

technical field [0001] The invention relates to a plant seed germination method, in particular to a method for germination of Dracaena glabrata seeds. Background technique [0002] Dracaena cochinchinensis (Lour) S.C.Chen is an evergreen tree of Liliaceae, distributed in Jingxi, Longzhou, Pingxiang, Daxin, Ningming and Zhenkang, Yulian, Puer in southwestern Guangxi. Counties such as Vietnam and Laos are also distributed. It has a beautiful tree shape and can adapt to the habitat of rock crevices. It can be used as an excellent foliage plant for rocky mountain greening plants and modern interior decoration. The resin obtained by extracting the fat-containing wood of the sword-leaf dracaena is called "Dragon's Blood", which has the functions of promoting blood circulation, dispersing blood stasis, relieving pain, hemostasis, promoting muscle regeneration and curbing sores, etc. It was included in the "Yunnan Provincial Drug Standards" in 1974. "In 1999, the Ministry of Healt...
