Embodiment 1-1
[0047] (1) Selection and disinfection of explants: The subterranean bulbs of Amaryllis lycoris, which grow vigorously and have basically the same size, are selected as explants at the stage of withered leaves for primary culture. The brown outermost layer of scales is peeled off, retained when the size of the bulb is stripped to 2cm, rinsed under running water for 60 minutes and then placed on an ultra-clean workbench. Cut off the root and 2 / 3 of the upper part of the bulb, and 1 / 3 of the remaining bulb for subsequent disinfection; wash the bulb twice with 200mg / L cephalosporin water, then wash it with 75wt.% alcohol for 30s, and then wash it with 0.5 Wash with wt.% benzalkonium bromide for 30 minutes, wash with sterile water for 5 times, and keep shaking the bulbs during the washing. Cut into 4 pieces according to the size of the bulb disk, each piece has 6 layers of scales and retains the base disk as explants.
[0048] (2) Induction of adventitious buds: the explants after...
Embodiment 1-2
[0051] Put the rootless tissue cultured seedlings obtained in Example 1-1 into the greenhouse, unscrew the bottle mouth of the tissue cultured seedlings in the greenhouse, inject a small amount of water into the bottle after 3 days, and take out the seedlings after hardening for 3 days. Gently take out the rootless test-tube seedlings of Lycoris after seedling hardening with tweezers. The rootless seedlings are soaked in a solution containing 0.2 mg / L IBA and 1 / 10,000 potassium permanganate for 5 minutes, rinsed with clean water, transplanted to a substrate for cultivation, and rooted Lycoris seedlings are obtained.
[0052] The transplanting medium contains peat: vermiculite: perlite, mixed according to the volume ratio of 12:10:1 and placed in a 10cm high square plate; after the square plate substrate is watered, the test tube seedlings are planted into the seedbed according to the row spacing of 5×6cm , when the test-tube seedlings are transplanted, all the small bulbs are ...
Embodiment 2-1
[0054] The proliferation culture cycle of embodiment 2-1 is 2 times, and all the other treatments are the same as embodiment 1-1.
