Abstract

The invention discloses a chemical mutagenesis processing device for plant material, wherein the chemical mutagenesis processing device for plant material comprises a frame (1), at least one mutagenesis processing chamber (5) and at least one continuous dosing chamber (4), wherein the at least one mutagenesis processing chamber (5) is used for placing plant material for mutagenesis, arranged on the frame (1) and provided with a medicine liquid inlet (15) and a discharge hole (19); the inside of the mutagenesis processing chamber (5) is provided with a temperature control heating device (16) which is used for heating the medicine liquid and detecting the temperature; at least one continuous dosing chamber (4) is used for holding the medicine liquid, arranged on the frame (1) to be corresponding to the mutagenesis processing chamber (5) and provided with the medicine liquid outlet (12); the height of the medicine liquid outlet (12) is greater than the height of the corresponding medicine liquid inlet (15); the medicine liquid outlet (12) is connected to the corresponding medicine liquid inlet (15) through the liquid inlet pipe (32); the liquid inlet pipe (32) is provided with a liquid inlet valve (31). Through the device, the best reaction temperature can be kept for the whole mutagenesis process; the activity of the mutagenic agent is guaranteed; the device is high in mutagenesis efficiency and good in effect.

Description

technical field [0001] The invention relates to the technical field of chemical mutagenesis of plant materials, in particular to a device for chemical mutagenesis treatment of plant materials. Background technique [0002] Chemical mutagenesis is carried out by using some chemical mutagens with unstable molecular structures, which cause biological damage and error repair through chemical reagents, and produce mutants. These mutations are mainly point mutations, and have some relatively high frequency and relatively stable mutation spectrum due to different reagents. Point mutations caused by single base pair changes are the main form of chemical mutagenesis. [0003] The traditional phytochemical mutagenesis treatment is to put the plant material directly into the triangular flask or culture bottle, then pour the mutagenic treatment solution into the bottle, after a period of treatment, pour out the treatment solution to take out the plant material, and then need to The en...

AI Technical Summary

Problems solved by technology

[0004] 1) The control of the influencing factors of chemical mutagenesis in the existing device is only the mutagen concentration and treatment time in the traditional operation, and other influencing factors such as the treatment temperature and the half-life of the mutagen are not included in the device within the controllable range;

[0005] 2) Existing devices can only process multiple materials under the same mutagenic condition, but for complex tests that require different conditions to be carried out at the same time, they can only be completed by dividing multiple times or using multiple devices at the same time, which not only increases the test input cost but also Affected the mutagenic effect;

[0006] 3) The existing plant material chemical mutagenesis device "forest chemical mutagen" can only conduct mutagenesis treatment for living tree buds, and has strict requirements on materials. Materials such as stem segments cannot be processed with this device;

[0007] 4) Although the existing device has achieved a certain degree of automatic control in the treatment process, the preparatory work needs to manually fix the instrument on the tree, which will not only cause certain damage to the plants to be treated but also be dangerous
