Embodiment 1

[0030] The present embodiment provides a kind of method for promoting the germination of the seeds of Rhizoma chinensis, comprising the steps of:

[0031] 1) Collection of seeds: Harvest the naturally cracked and mature water chestnut fruit from April to June of the year, rub to remove the peel, and dry naturally.

[0032] 2) Seed screening and disinfection: Put the water chestnut seeds dried naturally in step 1) into 0.1% potassium permanganate solution for 20-25 minutes for disinfection, rinse with distilled water after disinfection to remove residual high Potassium manganate solution.

[0033] 3) Seed sand storage treatment: Put the sterilized water chestnut seeds in step 2) into a plastic gauze bag (can be replaced by gauze bag or gauze bag made of other materials) from July to August of that year, tie the bag tightly, and put it directly After immersing in water for 24 hours, take it out; dig an 8-12cm deep pit outdoors, pour a layer of wet sand (hold it into a ball, and...

Embodiment 2

[0038] The present embodiment provides a kind of method for promoting the germination of the seeds of Rhizoma chinensis, comprising the steps of:

[0039] 1) Collection of seeds: Harvest the mature water chestnut fruit in June of that year, remove the peel, and dry naturally.

[0040] 2) Seed screening and disinfection: put the dried water chestnut seeds in step 1) into a 0.1% potassium permanganate solution for disinfection by soaking, and rinse with distilled water after disinfection to remove the remaining potassium permanganate on the surface of the seeds solution.

[0041] 3) Sand storage treatment of seeds: In mid-July of that year, the sterilized seeds of the chrysanthemum in step 2) were wrapped with plastic gauze, soaked in water for 24 hours, and placed outdoors at a depth of 10 cm from the ground surface for sand storage treatment.

[0042] 4) Seed high-temperature variable-temperature stratification treatment: The seeds treated in step 3) continue to be deeply burie...

Embodiment 3

[0046] The present embodiment is the test object with the chrysanthemum seeds collected in the same period, adopts different methods to carry out germination experiment, to compare the germination rate of different processing methods.

[0047] Control treatment 1: The naturally dried seeds of C. chinensis were stored under indoor conditions until the end of February. After soaking the seeds of C. chinensis in clean water for 24 hours, they were placed in a petri dish with a diameter of 9 cm and filter paper, and kept at a constant temperature of 23.5°C. Germinated in an incubator and cultured for 30 days. Open the constant temperature incubator for 2-4 minutes within a day, so that oxygen can fully enter the incubator to ensure the oxygen needed for seed germination. The cultivation experiments were all carried out under dark conditions, the germination of the seeds was observed every day, and proper water was added to the seeds.

[0048] Control treatment 2: use 20×10 -6 , ...

Abstract

The invention belongs to the technical field of sexual propagation of plants and discloses a method for promoting germination of seeds of rare and endangered plant saruma henryi. Harvested mature saruma henryi seeds are sequentially subjected to sand storage treatment in the same year, high-temperature temperature-accelerated stratification treatment under the natural conditions of summer and autumn and low-temperature stratification treatment under the natural condition in winter; the treated saruma henryi seeds are subjected to germination culture in a constant-temperature incubator next year. The saruma henryi seeds are sequentially subjected to sand storage treatment in the same year, high-temperature temperature-accelerated stratification treatment and low-temperature stratification treatment, the ideal germination rate can be obtained, the universal knowledge ofsaruma henryi seed germination difficulty is broken through, and the method has broad application prospects.

Description

technical field [0001] The invention belongs to the technical field of plant sexual reproduction, and relates to plant seed germination, in particular to a method for promoting the germination of rare and endangered plant chrysanthemum seeds. Background technique [0002] Horseshoe incense ( Saruma henryi Oliv.) is a perennial erect herb of the genus Saruma in the family Aristolochiaceae. It is a unique single-species plant in my country and occupies an important position in the phylogeny of Aristolochiaceae. Horseshoe incense is also a medicinal plant, and its roots and rhizomes can be used as medicine. At present, the horseshoe incense is in an endangered state, and there are many reasons for its endangerment, including its own reasons, as well as external and human factors. The main summary is: long-term artificial over-excavation and serious damage; in addition, it has strict requirements on habitats; Furthermore, C. chinensis has few flowers and few fruits, and its s...
