example 1

[0012] Adopt above-mentioned method to soak Eustoma kind in the magnetized water that contains salicylic acid 0.2mmol / L and carry out seed soaking; Magnetized water is to take clear water as water source, with 1m / h flow rate through the magnetic water device that magnetic induction intensity is 0.6T and obtains; The total soaking time is 12 hours.

example 2

[0014] Adopt above-mentioned method to soak Eustoma kind in the magnetized water that contains salicylic acid 0.5mmol / L and carry out seed soaking; Magnetized water is to take clear water as water source, with 1m / h flow velocity through the magnetic water device that magnetic induction intensity is 0.4T and obtains; The total soaking time is 14 hours.

example 3

[0016] Adopt above-mentioned method to soak Eustoma kind in the magnetized water that contains salicylic acid 0.05mmol / L and carry out seed soaking; Magnetized water is to take clear water as water source, with 1m / h flow velocity through the magnetic water device that magnetic induction intensity is 0.2T and obtains; The total soaking time is 16 hours.

[0017] Experimental method for the control group: 5 g of eustoma seeds (about 5000 grains) were soaked in water at 30° C. for 16 hours as a control. The seed selection, seed soaking method and seed soaking conditions were the same as those of the experimental group.

[0018] Evaluation indicators:

[0019] After 7 days, count the germination potential of seeds Germination potential (%)=germinated seeds number in 7 days ÷ total number of seeds × 100%

[0020] After 10 days, count the germination rate of seeds Germination rate (%)=10 days germinated seed number ÷ total number of seeds × 100%

[0021] After 30 days the dry wei...

Abstract

The invention belongs to the technical field of flower culturing, especially the technical field of eustoma grandiflorum propagation. A method for accelerating germination of eustoma grandiflorum seeds is characterized by comprising the following steps of: placing the eustoma grandiflorum seeds in magnetic water containing 0.05-0.5 mmol / L of salicylic acid to soak for 2-3 hours, fetching out the seeds, drying, then placing the seeds in the magnetic water to soak for 2-3 hours, repeating the above operation 3-5 times, wherein the total soaking time is 12-16 hours; the seed soaking conditions are as follows: the temperature is 23-27 DEG C; and the illumination is 2000-2500 Lx. The method in the invention obviously accelerates germination trend and germination ratio of the eustoma grandiflorum seeds; and the complete fresh weight of the seedling is obviously larger than that of the control group. The magnetic water is added with the salicylic acid so as to accelerate the growth of the adventitious roots so that the root system is relatively developed, and the survival rate of the seedling after being transplanted is largely improved.

Description

technical field [0001] The invention belongs to the technical field of flower cultivation, in particular to the technical field of eustoma propagation. Background technique [0002] Eustoma grandiflorum (Eustoma grandiflorum), also known as prairie gentian, is a taproot herb of one or two years, with erect stems and opposite leaves, which are ovate or oblong. Flowers solitary or in panicles. Eustoma seeds are very small, about 20,000 grains per gram, and about 1,000 grains per gram of coated seeds. There are specific requirements for temperature, humidity, moisture and light during the seedling raising period, so the germination rate and germination potential are low, and the seedling growth is weak, which affects the survival rate after transplanting. Contents of the invention [0003] The object of the present invention is to provide a method for accelerating germination of eustoma seeds, so as to improve the germination rate of eustoma seeds and the quality of seedlin...
