Embodiment 1

[0034] Embodiment 1 takes blue fir breeding as an example

[0035] S1: Seed selection: Select high-quality blue fir seeds with good maturity and full grains.

[0036] S2: High-voltage electrostatic field treatment: the intensity is 600KV / m, and the time is 24h.

[0037]1) Upper threshold for experimental determination: Under the same electric field strength of 600KV / m, set the following 10 time periods for electric field treatment: 0.1, 0.5, 1, 2, 4, 8, 12, 24, 48, 96 hours . 100 seeds are selected for each period of time and placed in a germination vessel, and then placed in a high-voltage electrostatic field processor for processing. After the treatment, soak the seeds, sow the seeds, observe and record according to the following steps S3-S5.

[0038] Experimental results: in the 7 stages before 24 hours, the blue fir seeds did not respond significantly to the electric field, and the germination rate did not change much; in the 24 hours stage, the germination rate was sup...

Abstract

The invention discloses a colored-leaf forest seed mutagenesis method based on a high-voltage electrostatic field. The method includes: utilizing physical mutagenesis performance of the high-voltage electrostatic field to perform high-dosage radiation on colored-leaf forest seeds and specifically includes: selecting seeds, treating through the high-voltage electrostatic field, soaking the seeds toaccelerate germination, recording germination rate, sowing, managing colored-leaf forest seed cultivation records, and transplanting for cultivation. The method is simple and easy in operation; a high-voltage electrostatic power source is simple in structure and low in cost. The colored-leaf forest seeds obtained by the method can have leaf color phenotype mutagenesis rate of 0.5-1%, a new technical scheme is provided for forest mutation breeding, and superiority of the method is about to emerge as high-voltage electrostatic field technology becomes mature.

Description

technical field [0001] The invention belongs to the technical field of plant cultivation, and in particular relates to a method for mutagenesis of colorful-leaved forest tree seeds based on a high-voltage electrostatic field. Background technique [0002] There is a natural electric field on the surface of the earth on which humans and creatures live. This natural electric field is generated by the ionosphere with a potential of 360KV and the earth with a potential of zero. The electric field strength near the earth's surface is about 130V / m. At the same time, about 1800C of positive charges flow into the ground through various channels in the atmosphere every second, and the various plants protruding from the ground are the important channels of this 1800C atmospheric current. . Various organisms living on the surface of the earth have been accustomed to this rich and complex electric field physical environment. Scientific research shows that atmospheric electric field and...
