Problems solved by technology

[0005] There are few reports on the in vitro cultivation of Pulsatillae, mainly focusing on explants such as seeds and leaves for in vitro culture. There is no report on how to use Pulsatilla pollen as explants to successfully cultivate Pulsatilla regenerated plants in vitro

Embodiment 1

[0078] The basal medium used for Pulsatilla anther-induced regeneration plants is MS modified medium, which consists of:

[0079] Macroelements: ammonium nitrate 1300mg / L, potassium nitrate 1500mg / L, potassium dihydrogen phosphate 210mg / L, magnesium sulfate 370mg / L and calcium chloride 400mg / L;

[0080] Trace elements: potassium iodide 0.86mg / L, boric acid 6.2mg / L, manganese sulfate (MnSO 4 4H 2 O) 22.3mg / L, zinc sulfate (ZnSO 4 ·7H 2 O) 8.6mg / L, sodium molybdate (Na 2 MoO 4 2H 2 O) 0.25mg / L, copper sulfate (CuSO 4 ·5H 2 O) 0.025mg / L and cobalt chloride (CoCl 2 ·6H 2 O) 0.025mg / L;

[0081] Iron salt: disodium edetate (Na 2 EDTA) 37.3mg / L and ferrous sulfate (FeSO 4 ·7H 2 O) 27.8mg / L;

[0082] Organic Matter: Inositol (C 6 h 12 o 6 2H 2 0) 100mg / L, Niacin (NC 5 h 4 COOH) 0.5mg / L, thiamine hydrochloride (C 12 h 17 ClN 4 OS·HCl) 0.1mg / L, pyridoxine hydrochloride (C 8 h 11 o 3 N·HCl) 0.5mg / L and glycine (NH 2 ·CN 2 · COOH) 2mg / L.

Embodiment 2

[0083] Example 2 Pulsatilla pollen induced culture regeneration plant

[0084] 1. Material collection and processing

[0085] From April to May, the fine wild varieties of Pulsatilla pulsatillae in Maoer Mountain, Harbin City, Heilongjiang Province were selected. At this time, the pollen is in the vigorous growth period, and the collection time is selected from 9 to 10 am in sunny weather. During the period from budding (emergence of flower buds) to flowering, flower buds were collected every 2 days. The collected flower buds were placed in a refrigerator at 4°C for 48 hours at low temperature and set aside.

[0086] Before inoculation, the stage of pollen development was identified by microscopic examination, and the pollen of Pulsatilla grandis in the middle stage of mononuclei was selected.

[0087] The microscopic examination method for determining the pollen development period is as follows: tear off the corolla with tweezers and take out the anthers, place the anthers ...

Embodiment 3

[0093] The culture medium and steps for inducing callus were the same as in Example 2, except that the developmental stage of the anthers was selected as the uninucleate marginal stage.

Abstract

The invention provides a basal medium for inducing and cultivating regenerated plants of Pulsatilla chinensis anthers, which belongs to the technical field of plant tissue culture, and improves the dosage of macroelements and some trace elements on the basis of MS medium. The Pulsatilla anther is induced and cultured on the basis of the basal medium provided by the invention, and the regenerated plant of the Pulsatilla anther is successfully induced. The present invention also provides a method for inducing and cultivating regenerated plants of Pulsatilla pulsatillae anthers. The anthers of Pulsatilla pulsatillae in the mononucleate stage are selected and inoculated in the induction medium, cultured in dark until green and bright buds are formed on the surface of the callus, and then transferred to the proliferation culture. Proliferate and cultivate in medium to induce the formation of clustered seedlings; transfer the clustered seedlings to rooting medium for culture, and obtain regenerated plants of Pulsatilla pulsatillae. By adopting the method provided by the invention to cultivate Pulsatilla anthers, the induction rate, multiplication rate and rooting rate are high, the culture time is short, and the efficiency of cultivating Pulsatilla regenerated plants is effectively improved.

Description

technical field [0001] The invention relates to the technical field of plant tissue culture, in particular to a basal medium, an induction medium, a proliferation medium and a rooting medium for inducing and cultivating regenerated plants of Pulsatilla pulsatillae anthers, and a method for inducing and cultivating regenerated plants of Pulsatilla chinensis anthers. Background technique [0002] Pulsatilla chinensis (Bunge) Regel, also known as sheep's beard flower, old crown flower, general grass, big bowl flower, husband flower, old sister-in-law flower and Maoguduo flower, is a plant of the genus Pulsatilla in the family Ranunculaceae. Plant height 15-35 cm, rhizome 0.8-1.5 cm thick, basal leaves 4-5, leaves broadly ovate, 3-lobed, middle segment stalked or nearly sessile, scape 1(-2), Plumber, erect flowers, sepals blue-purple, oblong-ovate, aggregate fruit 9-12 cm in diameter, achenes spindle-shaped, flat, flowering from April to May. Pulsatilla mostly grows in areas wi...
