A kind of rice anther dividing device

Abstract

The invention discloses a rice anther segmentation apparatus, which includes a housing (1); the housing (1) is internally provided with a paddle plate (13) with a paddle plate shaft (12); a link mechanism below the paddle plate (13) can drive the paddle plate (13) to reciprocate; the top of the housing (1) is provided with a sterilization mechanism; the sidewall of the housing (1) is provided with a discharge outlet (17) capable of cooperating with the paddle plate (13); the lower side of the discharge outlet (17) is provided with a transmission mechanism (18); the end of a transfer mechanism (18) is provided with a cutting board (19); a blade group (20) is above the cutting board (19); the end of the cutting board (19) is provided with a discharge port (21) and a storage bin (22) cooperating with the discharge port (21); the bottom of the cutting board (19) is provided with a drain pipe (16) with a liquid outlet valve (15) at the end. The device has simple structure, and is easy to use, applicable to cutting of rice anther, and improves anther culture efficiency.

Description

technical field [0001] The invention relates to a rice anther dividing device, which belongs to the field of rice flower cultivating equipment. Background technique [0002] Rice anther culture is the use of plant tissue culture technology to inoculate rice anthers that have developed to a certain stage on an artificial medium through aseptic techniques, change the developmental program of pollen grains in the anthers, induce their differentiation, and continuously undergo mitosis. The process of forming a cell mass, and then forming a group of undifferentiated parenchyma-callus, and then differentiating into a complete rice plant. [0003] Somatic cells (diploid) of rice have 24 chromosomes, and sex cells (pollen cells and egg cells, haploid) have 12 chromosomes. Haploid rice plants grown from pollen have only one set of chromosomes, that is, 12 chromosomes, and each homologous chromosome has only one member, so each allele has only one member. Rice is a self-pollinated p...

Problems solved by technology

Years of practical experience have found that the most important reason for the low efficiency of flower cultivation is the limitation of the operation method of flower cultivation

The method of cutting glumes and shaking herbs is currently the most common operation method for rice anther separation. However, the process of glume cutting and shaking herbs requires professional tissue culture operations and consumes a lot of labor, which has become the speed-limiting step of rice flower cultivation operations.

How to quickly separate rice anthers, and ensure that the rice anthers after separation maintain vigor and pollution-free and suitable for in vitro culture is the key to solving the low efficiency of flower culture operations
