Technical Field
[0001] This utility model relates to the field of plant explant culture technology, and in particular to a liquid tissue culture device for plant explants. Background Technology
[0002] Explants refer to various inoculation materials used in plant tissue culture. Theoretically, plant cells are totipotent and capable of regenerating new plants; any organ, any tissue, single cell, and protoplast can serve as an explant. Liquid tissue culture of plant explants uses liquid culture media, which, unlike traditional solid media, do not contain solidifying agents such as agar. Explants grow in a liquid environment, resulting in faster growth.
[0003] Existing liquid tissue culture devices for plant explants lack protective measures during the explant culture process, and explants are often infected by external bacteria, resulting in low culture survival rates. Utility Model Content
[0004] The purpose of this invention is to provide a liquid tissue culture device for plant explants. Large sterile cotton pads are placed inside the box, and small sterile cotton pads are also placed inside each culture box. This sterilizes the air entering the culture box, thereby reducing external bacterial infection and improving the survival rate of explants. The culture boxes are placed inside a limiting frame, and suction cups are used to adhere to the bottom of the culture boxes, thus stabilizing them. The sterile cotton pads adhere to the inner wall of the culture boxes, allowing the explants to attach to the sterile cotton pads and grow, thus providing more growth space for the explants.
[0005] To achieve the above objectives, a liquid tissue culture device for plant explants is provided, comprising: a box body, an inner ring fixedly connected to the inner wall of the box body, a large sterile cotton pad placed on the top of the inner ring, a suction cup and a limiting frame fixedly connected to the inner bottom surface of the box body, the suction cup being located inside the limiting frame, a culture component disposed inside the limiting frame, the culture component including a culture box, a placement ring, a sterile cotton pad and a small sterile cotton pad, a placement ring fixedly connected to the inner wall of the culture box, a sterile cotton pad fixedly connected to the bottom of the placement ring, a small sterile cotton pad placed on the top of the placement ring, a top cover snapped onto the top of the box body, an air inlet pipe fixedly connected to the top of the top cover, and a filter screen fixedly connected inside the air inlet pipe.
[0006] According to the aforementioned liquid tissue culture device for plant explants, the culture box is located above the suction cup.
[0007] According to the aforementioned liquid tissue culture device for plant explants, the cross-section of the sterile cotton pad is "L" shaped.
[0008] According to the liquid tissue culture device for plant explants, there are seven limiting frames and seven suction cups, which are evenly distributed inside the box.
[0009] According to the aforementioned liquid tissue culture device for plant explants, the number of culture components is set to seven, and they are evenly distributed inside the box.
[0010] According to the aforementioned liquid tissue culture device for plant explants, the sterile cotton pad is attached to the inner wall of the culture box.
[0011] According to the aforementioned liquid tissue culture device for plant explants, the box, culture container, and top cover are all made of tempered glass.
[0012] According to the liquid tissue culture device for plant explants, the bottom of the box is fixedly connected with a support column, and the number of the support columns is three, which are evenly distributed at the bottom of the box.
[0013] The above-mentioned solution has the following beneficial effects:
[0014] 1. By setting up a box, inner ring, large sterile cotton pads, culture box, placement ring, sterile cotton pads and small sterile cotton pads, the large sterile cotton pads are placed inside the box, and the small sterile cotton pads are also placed inside each culture box, which can sterilize the air entering the culture box, thereby reducing external bacterial infection and improving the survival rate of explants.
[0015] 2. By setting suction cups and a limiting frame, the culture box is placed inside the limiting frame, and the suction cups are used to adhere to the bottom of the culture box, thereby stabilizing the culture box.
[0016] 3. By setting up placement rings and sterile cotton pads, the sterile cotton pads fit snugly against the inner wall of the culture box, allowing explants to attach to the sterile cotton pads and grow, thus providing more growth space for the explants.
