Embodiment 1
[0027] Example 1: A method for tissue culture and rapid propagation of Acer quinquefolia includes the following steps:
[0028] (1) Sterilization of explants: Collect the young stems of Acer platyphylla without diseases and insect pests, remove the leaves, cut the stems into 2cm shoots with buds, and sterilize them with alcohol for 30s on a clean bench. Sterilize with mercury for 5 minutes, rinse with sterile water 4 times;
[0029] (2) Start-up culture: inoculate the sterilized stem with buds into the start-up medium, cultivate in the culture room for 2 weeks, and the axillary buds will extend 2cm;
[0030] (3) Primary culture: Cut off the axillary buds, inoculate them into the primary culture medium, and cultivate them in the culture room for 3 weeks to obtain robust rooted Acer platyphylla aseptic tissue culture seedlings. After 3 weeks of culture, the plants grow 6 cm. And rooting, the root system is developed, the number of roots is 2, the root length is 3cm, and the axillary ...
Embodiment 2
[0036] Example 2: A method for tissue culture and rapid propagation of Acer quinquefolia includes the following steps:
[0037] (1) Sterilization of explants: Collect the young stems of Acer platyphylla free of diseases and insect pests, remove the leaves, cut the stems into 3cm stems with buds, and sterilize them with alcohol for 60s on a clean bench. Sterilize with mercury for 8 minutes, rinse with sterile water 6 times;
[0038] (2) Start-up culture: Inoculate the sterilized stem with buds into the start-up medium, cultivate in the culture room for 3 weeks, and the axillary buds will extend 4cm;
[0039] (3) Primary culture: Cut off the axillary buds, inoculate them into the primary culture medium, and cultivate them in a culture room for 2 weeks to obtain robust rooted Acer spp. aseptic tissue culture seedlings. After 4 weeks of culture, the plants grow 7 cm. And rooting, the root system is well-developed, the number of roots is 12, the root length is 5cm, and the axillary buds...
Embodiment 3
[0045] Example 3: A method for tissue culture and rapid propagation of Acer quinquefolia includes the following steps:
[0046] (1) Sterilization of explants: collect the young stems of Acer platyphylla without pests and diseases, remove the leaves, cut the stems into 2.3cm stems with buds, and sterilize them with alcohol for 40s on a clean bench , Sterilized with mercury for 6min, rinsed with sterile water 5 times;
[0047] (2) Start-up culture: inoculate the sterilized stem with buds into the start-up medium, cultivate in the culture room for 16 days, and the axillary buds will extend 2.8cm;
[0048] (3) Primary culture: Cut off the axillary buds, inoculate them into the primary culture medium, and cultivate them in the culture room for 16 days to obtain robust rooted Acer palmatus aseptic tissue culture seedlings. After 23 days of culture, the plants grow 6.3 cm. And rooting, the root system is well-developed, the number of roots is 6, the root length is 3.5cm, and the axillary ...
