[0020] Establishment of Aseptic Culture System of Peony
[0021] Peony 'Fengdan'(Paenoia ostti T.Hong et J.X.Zhang var.Lishizhenii B.A.Shenin Acta Phytota.Sin.1997,35(4):360-361),'Star'(Paenoia suffruticosa Andr.'Mingxing'),' For Wengonghong' (Paenoia suffruticosa Andr.'Wengonghong') etc., select robust plants, and collect healthy and plump scale buds free from diseases and insect pests as explants from October of that year to March of the next year, and dip them in baby bath soap with a soft brush Clean the surface, soak in an aqueous solution of chloro-m-xylenol (trade name: Dettol) (35-50ml per liter of chlorinated-m-xylenol) for 5-10min (during gentle shaking), rinse with running water for 20min, add 28 Mixture of % hydrogen peroxide and 70% ethanol (3:1, volume ratio), drop into Tween-80 (0.2ml per 50ml of mixture is 1 drop), sterilize for 8-15min, rinse with sterile water 3-4 times, 3 minutes each time. Put the scale buds on sterilized filter paper to drain the surface...

[0023] Tissue Culture Propagation of Peony Test-tube Seedlings (Adventitious Buds)
[0024] The preferred plants of peony 'Fengdan' (Paeonia ostii T.Hong et J.X.Zhang var.lishizheniiB.A.Shen) and 'Star' (Paenoia suffruticosa Andr.'Mingxing') were collected in January with healthy and full scale buds according to the implementation The method described in Example 1 establishes an aseptic culture system; axillary buds are cultivated in a tissue culture room on WPL value-added medium (medium formula and preparation method are the same), and the conditions of the tissue culture room are temperature 23-25 ° C, light 36 μmol / m 2 / s, the daylight rhythm is 16h / 8h (light / dark), and the air is ventilated by cellulose acetate membrane filtration. The cultures were grown under these conditions for 28 days, and each culture differentiated 2-5 adventitious buds. The theoretical reproductive quantity is calculated according to the formula y=x n (y is the reproduction quantity, x is the ...

[0027] Peony tissue culture container seedlings
[0028] Peony 'Fengdan' (Paenoia ostti T.Hong et J.X.Zhang var.LishizheniiB.A.Shen) obtained test-tube plantlets according to the above-mentioned embodiment one and two. The test-tube seedlings are cultivated into tissue culture container seedlings adapted to the field environment through the following three stages. (1) Container seedling culture, test-tube seedlings take root to form container seedlings through the following cultivation process: rooting mixed substrate [charcoal (particle size ≤ 5mm) or perlite and peat (2:1, v:v), activated carbon 1g / L] Put into a black polyethylene nutrition bowl (3-4.5cm×3-4.5cm, diameter×height), put the nutrition bowl into a transparent tissue culture bottle (about 7.5cm×10cm, diameter×height); add rooting culture solution into the culture bottle 40ml [each liter contains 1 / 3-1 / 2WPL inorganic substances, indole butyric acid 1-3mg, and the rest is water]; high-temperature sterilization (te...
